SanRex — SQD400A60S Dual Darlington Transistor Module 600 V • 400 A • Dual Darlington transistors with reverse-parallel fast-recovery diodes • Isolated baseplate
What it is

600 V, 400 A dual Darlington power transistor module (SanRex SQD series) for high-current converters, VVVF motor control, UPS front ends, and industrial power supplies. Each transistor includes a reverse-parallel fast-recovery diode; the mounting base is electrically insulated for straightforward heatsink design.

At-a-Glance
  • Voltage / Current: 600 V / 400 A
  • Topology: Dual Darlington transistors with reverse-parallel FRDs
  • Mounting: Screw-mount, isolated baseplate
  • Use Cases: VVVF/AC motor drives; UPS/inverters; high-current DC supplies
  • Condition Options: New old stock or tested reclaimed pulls
Features
  • Low VCE(sat) — Darlington structure optimized for high current conduction.
  • High gain — large hFE for reduced base-drive requirements at high current.
  • Fast-recovery diodes — reverse-parallel FRDs for clean commutation.
  • Isolated baseplate — simplifies heatsink and grounding strategy.
