What it is

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

At-a-Glance
  • Voltage / Current: 1600ย V / 70ย A ITAV (โ‰ˆย 110ย 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 โ€” ITSM โ‰ˆ 1.5โ€“1.6ย kA (1-cycle, 50/60ย Hz, non-rep.).
  • Rugged dynamics โ€” (di/dt)cr โ‰ˆ 100ย A/ยตs; (dv/dt)cr โ‰ˆ 500ย V/ยตs.
  • Low on-state drop โ€” VTM โ‰ˆ 1.35ย V @ IT=210ย A, 25ย ยฐC (max).
  • Isolated base โ€” 2.5ย kVRMS/1ย min hi-pot simplifies heatsinking/grounding.
