IR Presents MTP Switch Family of IGBT Modules
International Rectifier Corp. (El Segundo, CA) introduced the MTP Switch family of IGBT modules insulated with a ceramic aluminum-nitride layer for improved junction-to-case thermal resistance, which enables as much as seven times better thermal conductivity (cooling capability) than alumina substrates. The new 600V and 1,200V modules combine high-speed IGBTs with optimized diodes to form single-package, space-and-assembly, cost-saving alternatives to discrete solutions. The new modules are designed for high-current industrial power supplies used in high-frequency arc welding machines and uninterruptible power supplies.
The 50MT060ULS is a fully insulated, low-side chopper module, made with an ultra-fast IGBT and a HEXFRED® diode with UltraSoft reverse-recovery current. The 50MT060WH is a fully insulated, half-bridge module built with a pair of WARP Speed™ IGBTs in parallel and a HEXFRED free-wheeling diode with UltraSoft reverse-recovery current characteristics. The double-IGBT layout enables efficient power dissipation and current sharing.
Two additional MTP Switch modules are available, with 1,200V ratings. The fully insulated 20MT120UF full-bridge and the 40MT120UH half-bridge modules host 1,200V-rated IGBTs. The 1,200V devices can be directly connected to the dc bus in the majority of three-phase systems. The half-bridge module is available with on-board temperature monitoring.
Samples are available now. Pricing for the 50MT060ULS is $40 each, $52 each for the 50MT060WH, and $42 each for the 20MT120UF and 40MT120UH in 1,000-unit quantities.
