SanRex Semi-PAK — SBAU-33C (SUM11P055) Thyristor Module 1600 V • 70 A ITAV • Dual phase-control thyristors (anti-parallel) • Isolated baseplate
What it is

Semi-PAK dual SCR module used for single-phase AC control/rectifiers. The ratings below follow the common SanRex PK-series 70 A / 1.6 kV class used in this package style for drop-in service.

At-a-Glance
  • Voltage / Current: 1600 V / 70 A ITAV (≈ 110 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; soft-starts; static switches
  • Package: Semi-PAK / PK70-class footprint with stud power terminals
Features
  • High surge capability — ITSM ≈ 1.5–1.6 kA (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=210 A, 25 °C (max).
  • Isolated base — 2.5 kVRMS/1 min hi-pot simplifies heatsinking/grounding.
