Features:
- Module identity: SEMIPACK 5 thyristor/diode rectifier assembly.
- Electrical class: 570 A average current with 1600 V repetitive blocking.
- Thermal path: Aluminium-nitride isolation transfers heat to the metal baseplate.
SKKH570/16E is identified by both the SKKH circuit family and the complete 570/16 E rating code.
The pressure-contact construction and isolated baseplate define how the module carries current while coupling thermally to a heatsink.
Before fitting, compare the circuit symbol, terminal hardware and SEMIPACK 5 footprint with the installed assembly.
Apter Power can help verify the SEMIKRON DANFOSS SKKH570/16E voltage class, housing and terminal arrangement before quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Controlled path: The thyristor portion provides the gated conduction element within the rectifier topology.
- Diode path: The companion diode completes the SKKH circuit arrangement rather than the dual-thyristor layout used by SKKT variants.
- Voltage boundary: Repetitive off-state and reverse ratings are both 1600 V.
- Current boundary: Continuous RMS operation is limited to 1000 A even though surge values are higher and time-limited.
- Baseplate interface: The isolated aluminium-nitride ceramic layer carries heat toward the mounting surface.
- Heatsink hardware: M6 mounting screws use a 4.25–5.75 Nm tightening range.
- Main terminals: M10 connections use 10.2–13.8 Nm.
- Temperature ceiling: Junction temperature is limited to 135 °C and storage to 125 °C.
- Gate threshold: Maximum trigger voltage is 3 V at 25 °C.
- Trigger current: Maximum gate trigger current is 200 mA at 25 °C.
- Commutation interval: Maximum turn-off time is 200 µs at 135 °C.
- Voltage rise: The critical dv/dt rating is 1000 V/µs at the specified junction temperature.
- Motor-drive rectifiers: The module is listed for rectifier stages feeding motor-drive power converters.
- Process control: Controlled power conversion is included among the documented operating contexts.
- Power supplies: High-current rectification for power-supply equipment is an identified role.
- Selection check: Each use still requires coordination of heatsink, gate drive, voltage class and current duty.
