SanRex — PK55F-160 Thyristor Module 1600 V • 55 A ITAV • Dual phase-control thyristors (anti-parallel) • Isolated baseplate
What it is

Compact 1.6 kV, 55 A dual SCR module for AC power control and rectifiers. The anti-parallel topology provides bidirectional control for single-phase loads. An electrically isolated base simplifies heatsinking in tight power stacks.

At-a-Glance
  • Voltage / Current: 1600 V / 55 A ITAV (≈ 85–90 A ITRMS)
  • Topology: Dual thyristor (anti-parallel), phase-control
  • Mounting: Screw-mount, isolated baseplate (M6 mounts / M5 terminals)
  • Use Cases: Rectifiers; AC motor/heater control; dimmers; static switches; soft-starts
  • Condition Options: NOS or tested reclaimed pulls
Features
  • High surge capability — ITSM ≈ 1200 A (1-cycle, 50/60 Hz, non-rep.).
  • Rugged dynamics — (di/dt)cr ≈ 100 A/µs; (dv/dt)cr ≈ 500 V/µs.
  • Low on-state drop — VTM ≈ 1.35 V @ IT=165 A, 25 °C (max).
  • Isolated baseplate — 2.5 kVRMS / 1 min base-to-terminals hi-pot.
