Semikron Danfoss SKKH570/16E SEMIPACK 5 Thyristor-Diode Rectifier Module
A 570 A, 1600 V SEMIPACK 5 rectifier module combining thyristor and diode technology on an isolated metal baseplate.
Product Overview
SKKH570/16E corresponds to the Semikron Danfoss designation SKKH 570/16 E and product number 230B1784. It is a thyristor-diode rectifier module in the SEMIPACK 5 housing.
The module is rated in the 570 A current and 1600 V voltage classes. Heat is transferred through an aluminium-nitride ceramic isolated metal baseplate, and the internal pressure-contact construction supports the documented high-reliability assembly.
Mechanical fit, heatsink design, clamping, gate-drive arrangement and thermal interface remain part of the application. A same-housing module with a different voltage or topology must not be treated as interchangeable from outline dimensions alone.
Performance
Control a high-current rectifier path
The thyristor-diode topology supports controlled rectification in matched industrial power-conversion circuits.
Transfer heat through an isolated base
The aluminium-nitride ceramic base provides the documented thermal path to the heatsink while maintaining the isolated module construction.
Use pressure-contact assembly
Internal pressure contacts form part of the SEMIPACK 5 reliability design.

FAQ
What mechanical information should accompany an SKKH570/16E enquiry?
Provide the heatsink drawing, module position, clamp or fastener arrangement, busbar geometry and available clearance.
Can SKKH 570/18 E replace SKKH570/16E?
No direct substitution should be assumed: the /18 module has a different voltage class and must be reviewed against the complete converter design.
What thermal evidence matters before installing SKKH570/16E?
Record heatsink condition, interface material, mounting pressure and the prior module temperature history or failure evidence.
Which circuit details help confirm SKKH570/16E compatibility?
Send the rectifier schematic, gate-drive data, snubber values, semiconductor fuses and normal current profile.
How should SKKH570/16E be accepted after replacement?
Complete isolation and gate checks, then verify controlled firing, current, temperature rise and protection operation under the approved load test.
