Mitsubishi Electric to Launch MOSFET-type Super-mini DIPIPM

Mitsubishi Electric Corporation (TOKYO:6503) announced today it will launch a transfer-mold-type, super-mini dual inline package intelligent power module (DIPIPM) primarily used for inverter drive systems of small-capacity motors in refrigerators and other consumer appliances. The module uses a metal oxide semiconductor field effect transistor (MOSFET) switching device featuring low power-on voltage in low current regions. 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.

Product Features

1) Reduced power consumption in small-capacity inverter systems

  • Power-on voltage in low current regions is reduced by about 60% compared to Mitsubishi Electric's existing "PS219B2" DIPIPM at 0.5A and 25 degrees Celsius, by employing a MOSFET switching device.
  • Reduction of recovered-power loss by optimizing the MOSFET process.
  • Reduction of IC power loss by optimizing the control IC.

2) High reliability through high-heat dissipation structure

  • Suppression of channel temperature rise by reducing power loss of switching device and applying a high-heat dissipation insulation sheet.

3) Cost reduction and miniaturization of final product

  • Facilitation of thermal radiation via the high-heat dissipation design.
  • Reduction of external components thanks to built-in bootstrap diode (BSD) with current limiting resistor.

In 1997, Mitsubishi Electric first commercialized its DIPIPM transfer-mold-type intelligent power module, which has contributed greatly to miniaturization and energy-savings in inverter systems. The technology has gained increased importance because annual power consumption has become an important index of energy-saving performance in consumer appliances, such as refrigerators. Needs are increasing for reducing loss in rated power, and also in low current regions where a high percentage of power use is concentrated.

DIPIPM is a registered trademark of Mitsubishi Electric.
