Mitsubishi to Launch MOSFET-based Super-mini DIPIPM for 3-Phase Inverters

Mitsubishi Electric Corporation will launch a transfer-mold-type, super-mini dual inline package intelligent power module (DIPIPM) primarily designed for use in inverter drive systems of small-capacity motors in refrigerators and other consumer appliances. The modules will incorporate 500V power MOSFETs and sales will begin on March 1. With optimized low-loss-drive ICs and a high-heat dissipation design, the module will help to reduce power consumption, advance miniaturization and lower the cost of inverter systems for small-capacity motor drive applications.

Reduced power consumption in small-capacity inverter systems is improved as a result of a 60% reduction in the on-resistance of the power switches compared to Mitsubishi Electric's existing "PS219B2" DIPIPM at 0.5A and 25 degrees C.; A reduction of recovered-power loss by optimizing the MOSFET process; And a reduction of IC power loss by optimizing the control IC.

Parts count in inverter systems is reduced as a result of the built-in bootstrap diode and current limiting resistor. Both the 3A/500V model PSM03S93E5/-A/-C and the 5A/500V model PSM05S93E5/-A/-C will begin shipping March 1st. Both devices include a full three-phase bridge incorporating 6 power MOSFETs as well as control and drive ICs. Additional features include, protection against short circuits, control power-supply undervoltage and over-heating (LVIC monitoring); and an error output. The DIPIPM package measures 24mm X 38mm X 3.5mm.
