Vishay Intertechnology IGBT Power Modules Increase Efficiency and Reduce Conduction Losses in TIG Welding Machines
Built on Trench PT IGBT Technology, Half-Bridge and Single-Switch Devices Offer Low VCE(ON) and Eoff for High-Current Inverter Stages
MALVERN, Pa. — Jan. 19, 2016 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced four new half-bridge and single-switch IGBT power modules designed specifically for TIG welding machines. Built on Vishay’s proprietary Trench PT IGBT technology, the VS-GP100TS60SFPBF, VS-GP250SA60S, VS-GP300TD60S, and VS-GP400TD60S provide extremely low collector-to-emitter voltages down to 1.10 V and turn-off switching energy down to 11 mJ for output inverter stages.
With their Trench PT IGBT construction, the Vishay Semiconductors devices released today achieve a smaller size than planar IGBTs, providing designers with higher current density and lower thermal resistance (junction-to-case) without compromising on performance. The devices’ low collector-to-emitter voltage enables extremely low conduction losses, while their turn-off switching energy is 50 % lower than previous-generation devices for increased efficiency and long-term reliability.
The half-bridge VS-GP100TS60SFPBF, VS-GP300TD60S, and VS-GP400TD60S combine Trench PT IGBTs with HEXFRED® and FRED Pt® anti-parallel diodes in the INT-A-PAK package and dual INT-A-PAK package with an extremely low profile of 17 mm. The single-switch VS-GP250SA60S features the SOT-227 package, provides very low stray inductance of ≤ 5 nH typical, and is UL-approved file E78996.
The RoHS-compliant modules feature operating frequencies to 1 kHz, 600 V collector-to-emitter voltages, and continuous collector current from 100 A to 400 A. The devices can be directly mounted to heatsinks and offer low EMI to reduce snubbing requirements.
