J1-Series Power Modules Enhance Automotive Efficiency & Reliability
PDF
Overview

In 1997, Mitsubishi Electric first began producing power semiconductor modules designed specifically to meet the stringent reliability and safety standards required for electric and hybrid electric vehicle propulsion. Continuous innovation in packaging and power chip technology, combined with almost 20 years of real world on-road experience, has led to the development of the industry’s most advanced automotive power modules, the J1-Series.

Powerex exclusively provides sales, marketing, strategy and logistics support for Mitsubishi Power Semiconductor devices in the Americas.


Benefits and Features of the J1-Series Modules

  • Compact 6-in-1 Package: Lighter (360g) and requires less space than previous solutions (120mm x 115.2mm x 31mm)
  • Direct Cooling Structure: Integrated “Pin-fin” design improves heat radiation while decreasing thermal impedance and inverter weight
  • Specific Automotive Application Design: Meets automotive grade quality and reliability requirements
  • High Performance Carrier Stored Trench-gate Bipolar Transistor (CSTBT™) Chips: Allow for low VCE(sat) and low on-state losses. Chips include built-in current and temperature sensing.
  • High Reliability: Direct lead bonding improves thermal cycle lifetime while reducing parasitic resistance and inductance.
  • High Levels of Traceability: Allow for material and component management throughout the production process
  • RoHS Compliant: Completely lead (Pb)-free, including terminal plating

Components for Module Evaluation (J1-Series Evaluation Kit)

The J1-Series Evaluation Kit includes the driver board, the J1-Series power module, DC-Link Capacitor and cooling jacket.

These components can ONLY be used for bench tests and not for actual vehicle tests.



J1-Series Driver Board (J1RB-3)

Driver board is based on M81603JFP Gate Driver IC that is in production.



Features
J1-Series Driver Board (J1RB-3)
  • Optimized gate driver circuit
  • Magnetic optocoupler isolation
  • Built-in isolated DC-DC power supply (DC15V x 4CH, DC5V x 1CH)
  • Over-current protection (SC, OC) utilizing on-chip current sensor
  • Temperature compensation for SC, OC protection
  • Over-temperature (OT) protection
  • PN over-voltage (OV) protection
  • Switching speed optimization at high temperature, turn-off loss (Eoff) reduction
  • Short-pulse short-circuit protection (soft shutdown)
