International Rectifier has expanded its family of highly integrated, ultra-compact, patent pending µIPM power modules with the introduction of the IRSM808-105MH and IRSM807-105MH, optimized for high efficiency appliance and light industrial applications with motor power up to 300 W.
Available in an ultra-compact 8 x 9 x 0.9 mm PQFN package, the IRSM808-105MH and IRSM807-105MH half-bridge power modules offer up to a 60 percent smaller footprint than existing 3-phase motor control power ICs to provide a highly compact heatsink-free solution for applications including compressor drives for refrigeration, pumps for heating and water circulation, air-conditioning fans, dishwashers, and automation systems.
IR's patent pending µIPM product family offers a scalable power solution with common pin-out and package size. Featuring the most rugged and efficient high-voltage FredFET MOSFET switches optimized for variable frequency drives and IR's most advanced high-voltage driver ICs, the µIPM product family offers DC current ratings ranging from 2 A to 10 A and voltages of 250 V and 500 V. The new approach pioneered by IR for this market segment utilizes PCB copper traces to dissipate heat from the module, providing cost savings through a smaller package design and eliminating the need for an external heat sink. By using standard packaging QFN technology, assembly is simplified by eliminating through-hole second pass assembly and improving thermal performance compared to traditional dual-in-line module solutions.
Pricing begins at $1.44 each for both the IRSM808-105MH and IRSM807-105MH in 10,000-unit quantities. Production quantities are available immediately. The devices are RoHS compliant and prices are subject to change.
