Vishay Intertechnology Launches New High-Voltage Thin Film Resistor Divider Network in Compact Surface-Mount 1206 Case Size

Vishay Intertechnology Inc. introduced a new high-voltage thin film resistor divider network that offers a compact, higher-precision alternative to functionally equivalent products built on thick film technology. The new Vishay Dale Electro-Films HVRD features an absolute tolerance to 1 %, ratio tolerance to 0.1 %, absolute TCR as low as +/- 50 ppm/degC, and TCR tracking of +/- 10 ppm/degC. Offered in a surface-mount 1206 format, the HVRD is compatible with high-speed assembly equipment, with edge castellation to allow visual inspection of solder joints. Featuring a high 120 V maximum operating voltage, the HVRD will be used for voltage division in power converters, battery management circuitry, high-voltage test equipment, renewable energy and smart grid systems, and a wide range of industrial applications.

Vishay Intertechnology, Inc. Introduces MOS Barrier Schottky Rectifiers

Vishay Intertechnology Inc. introduced 15 new 200 V Gen-2 TMBS(R) Trench MOS Barrier Schottky rectifiers featuring a wide range of current ratings from 5 A to 30 A in four power package options. With low forward voltage drops down to 0.65 V typical at 15 A, the rectifiers offer high-efficiency operation for telecom power supplies and LED lighting applications. All devices released are available in the power TO-263AB and TO-262AA packages. The 5 A V(B,I)T5202 is also offered in the TO-220AC, while the 10 A V(B,I)T10202C, 20 A V(B,I)20202G and V(B,I)20202C, and 30 A V(B,I)30202C are available in the TO-220AB. The rectifiers feature a high maximum operating junction temperature of +175 degC. The TO-263AB package offers an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of 245 degC. The TO-220AB, TO-220AC, and TO-262AA packages feature solder bath temperatures of 275 degC maximum, 10 s, per JESD 22-B106. The devices are compliant to RoHS Directive 2011/65/EU and halogen-free according to JEDEC JS709A standards.

Vishay Intertechnology, Inc. Announces its 500 V High-Voltage MOSFETs Built on E Series Super Junction Technology

Vishay Intertechnology Inc. announced the first MOSFETs in a new 500 V family that features the same benefits of low conduction and switching losses as the company's 600 V and 650 V E Series devices. The low on-resistance and gate charge of the new devices will play a key role in saving energy in high-power, high-performance consumer products, lighting applications, and ATX/silver box PC switch mode power supplies (SMPS). Built on second-generation Super Junction Technology, the new Vishay Siliconix SiHx25N50E 500 V MOSFETs provide a high-efficiency complement to Vishay's existing 500 V D Series components based on high-performance planar technology. The 25 A devices feature low on-resistance of 145 m in a variety of package options, including the TO-220 (SiHP25N50E), TO-247AC (SiHG25N50E), and the thin leaded TO-220 FULLPAK (SiHA25N50E), which offers a low profile optimized for slim consumer products. The new MOSFETs provide ultra-low gate charge of 57 nC and low gate charge times on-resistance, a key figure of merit (FOM) for MOSFETs used in power conversion applications.

Vishay Intertechnology Inc. Announces New 1 MBd and 10 MBd VOW Widebody High-Isolation, High-Speed Optocoupler Family With 10 mm Creepage

Vishay Intertechnology Inc. announced that the company is expanding its VOW Widebody family of high-isolation optocouplers with a new series of high-speed devices capable of 1 MBd and 10 MBd data rates. Designed to increase reliability in high-voltage alternative energy and industrial applications, the VOW135, VOW136, VOW137, and VOW2611 provide a VIOTM of 8000 V, VIORM of 1414 V, and offer an external creepage distance of greater than 10 mm. The Vishay Semiconductors VOW Widebody optocouplers released consist of a GaAIAs infrared emitting diode, optically coupled with an integrated photo detector. In addition to the increased robustness provided by their high safety isolation, the devices feature an internal Faraday shield to provide the very high input-to-output noise isolation required by high-power switching applications. The VOW135, VOW136, VOW137, and VOW2611 are designed to isolate low- to high-voltage circuits in alternative energy systems such as solar inverters and in industrial applications such as motion and motor control and welding equipment. Eliminating the need for expensive conformal-coated solutions, the VOW Widebody devices allow designers to meet domestic and international safety agency requirements at a low cost and with a small form factor. The VOW135 and VOW136 offer common mode transient immunity of 1000 V/s and high- and low-level propagation delay of less than 2 us at a data rate of 1 MBd. VOW137 and VOW2611 devices provide a data rate of 10 MBd and boost common mode transient immunity up to 40000 V/s while keeping high- and low-level propagation delay at less than 100 ns and high pulse width distortion less than 40 ns. The VOW Widebody optocouplers are offered with a high creepage distance of more than 10 mm in DIP-8 400 mil Widebody through-hole and surface-mount lead-bend packages. The devices are compliant to RoHS Directive 2011/65/EU, conform to Vishay "Green" standards, and are certified to UL, cUL, VDE, and CQC 5000 m reinforced insulation requirements.

Vishay Intertechnology's Wireless Charging Receiving Coil Delivers High Efficiency for 10 W Applications

Vishay Intertechnology Inc. announced a new powdered-iron-based, WPC-compliant (Wireless Power Consortium) wireless charging receiving coil designed for 10 W applications. Offering a durable construction and high permeability shielding, the new Vishay Dale IWAS-4832FE-50 provides high efficiency greater than 70 % for wireless charging up to 10 W for portable electronics, including tablets, notebook computers, and handheld medical equipment. The IWAS-4832FE-50's high-saturation powdered iron is not affected by permanent locating magnets, and the device blocks charging flux from sensitive components and batteries. As an alternative to ferrite-based solutions, which can saturate in the presence of a strong magnetic field, the IWAS-4832FE-50 offers a magnetic saturation of < 50 % at 4000 gauss. The RoHS-compliant device features inductance of 15 uH at 200 kHz with a +/- 5 % inductance tolerance, DCR of 255 m at + 25 degC, and Q of 60 minimum at 200 kHz. The IWAS-4832FE-50's rated current of 2 A enables 10 W of charge at 5 V. The receiving coil features a lead length of 50 mm and tinned length of 10 mm.
