This document provides technical specifications for the Semikron SKKT 41/56 and SKKH 41/56 Thyristor/Diode Modules. It covers maximum continuous operating values under various ambient temperatures and outlines key features such as heat transfer through a ceramic isolated metal baseplate.
| Maximum continuous current (SKKT 41) | 7A |
|---|---|
| Maximum continuous current (SKKH 56) | 9A |
| Maximum continuous current (SKKT 56) | 48A |
| Maximum continuous current (SKKH 41) | 60A |
| Maximum surge current (SKKT) | 1000 A |
The modules are rated for operation up to an ambient temperature of 125°C.
The SKKT and SKKH series modules have a maximum continuous current of 48A or 60A depending on the specific model, measured with a conduction angle of sin(180)°.
The specified tightening torque for busbars to terminals is 3 Nm, which is approximately 26 Ib. in.
