International Rectifier has released a series of 600V intelligent power modules with open emitter pins for advanced appliance motor drive applications including air conditioners, fans, compressors, and washing machines.

The second-generation IRAM series leverages the company's trench IGBTs and three-phase gate driver IC in a fully isolated, thermally-enhanced package. It promises to deliver high level of protection and fail-safe operation with the inclusion of the following: a built-in high precision temperature monitor and over-current protection feature, short-circuit rated IGBTs, and integrated under-voltage lockout function.

The series employs a single-in-line package with full transfer mould structure and CTI>600, minimising PCB space and resolves isolation problems to heatsink.
