Common Applications
Product Precautions
Semikron Danfoss SKKH570/18E, catalog number 230B1785, is an in-production SEMIPACK 5 thyristor/diode rectifier module for high-current controlled rectifier stages.
- 570 A rated current
- 1800 V voltage class
- Thyristor / diode topology
- AlN isolated baseplate
The module combines a controlled thyristor path and a diode path in an electrically isolated SEMIPACK 5 housing. Heat-sink preparation, mounting force, terminal torque and gate-circuit records determine whether the published electrical and thermal capability can be used safely.
Important Notice: Match SKKH570/18E with catalog number 230B1785 and legacy part 07898730; do not substitute an SKKT, SKKH voltage variant or another SEMIPACK size by appearance alone.
