Mitsubishi Electric to launch MOSFET-type super-mini DIPIPM

JAPAN: Mitsubishi Electric Corp. 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 geatures
Reduced power consumption in small-capacity inverter systems
* Power-on voltage in low current regions is reduced by about 60 percent 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.

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.

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.
