More Information

Overview Manuals Circuit Arrangement Mounting Limits Gate Control Documented Uses

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.

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.
Description
SEMIKRON DANFOSS SKKH570/16E is a SEMIPACK 5 thyristor/diode rectifier module. It combines a gate-controlled thyristor path and a diode path in one isolated power-semiconductor assembly.

Inside SKKH570/16E, the semiconductor chips transfer heat through aluminium-nitride ceramic to the isolated metal baseplate, while pressure contacts carry the high-current connection. This construction links electrical loading directly to heatsink contact and mounting quality.

The rating of SKKH570/16E combines a 570 A current class with 1600 V repetitive blocking capability, but usable current remains dependent on case temperature and cooling. Its surge value describes short-duration events and cannot replace the continuous-current limit during selection.

For installation, SKKH570/16E uses the SEMIPACK 5 footprint with separate heatsink fasteners, main power terminals and a thyristor gate connection. Its documented rectifier roles include motor drives, process control and power-supply conversion.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which identifiers should be matched before ordering SKKH570/16E?
Match the complete SKKH 570/16 E marking, SEMIPACK 5 housing and product code 230B1784. The former part number 07898725 can support identification, but the electrical and mechanical identity must still agree.
How can SKKH570/16E be distinguished from the similarly rated SKKT module?
Check the circuit designation, not only the current and voltage class. SKKH570/16E uses a thyristor/diode arrangement, while an SKKT designation refers to a different internal topology.
What mechanical details should be compared before fitting SKKH570/16E?
Compare the SEMIPACK 5 outline, mounting-hole pattern, main-terminal hardware and heatsink interface with the installed assembly. A matching current rating alone does not confirm mechanical fit.
Why does heatsink condition matter when selecting SKKH570/16E?
The rated current is tied to case temperature, and heat leaves the chips through the isolated baseplate. Heatsink contact, mounting pressure and cooling therefore affect the usable current boundary.
What should be checked in the gate circuit before energizing SKKH570/16E?
Confirm that the gate drive matches the documented trigger requirements and that wiring follows the thyristor/diode circuit diagram. Do not infer gate compatibility from the SEMIPACK 5 housing alone.
Can the SKKH570/16E surge-current value be treated as a continuous rating?
No. The surge figure applies to a short specified event and changes with junction temperature. Continuous operation must be based on the average and RMS current limits together with the cooling conditions.
