What is the maximum continuous current rating of the AMKT 26-16E?

The module is rated for 26A average forward current at 85°C case temperature, or 32A at 68°C case temperature. Peak surge on-state current reaches 480A. These ratings determine the maximum load current your system can safely handle in continuous operation.

What cooling requirements does this thyristor module have?

With 0.95°C/W junction-to-case thermal resistance and 125°C maximum junction temperature, heatsink requirements depend on application power dissipation. Calculate required heatsink capacity using: Rth(heatsink) = (125°C - ambient) / power loss - 0.95°C/W. Proper thermal management ensures reliable long-term operation.

Is the AMKT 26-16E compatible with existing SKKT 26/16E equipment?

Yes, the AMKT 26-16E is a direct replacement for the Semikron SKKT 26/16E. Both modules share identical electrical specifications, 1600V voltage rating, 26A current rating, and standard SEMIPACK 1 package dimensions (93×20×30mm), enabling seamless substitution.

What applications is this module designed for?

The AMKT 26-16E suits DC motor control, AC soft starters, power conversion, industrial AC regulators, and welding equipment. Its dual thyristor topology with independent gate control supports phase-control and converter applications requiring precise switching and high reliability.

What is the turn-off time and why does it matter?

Maximum turn-off time is 80µs. This parameter determines the module's switching speed and maximum operating frequency. Faster turn-off enables higher switching frequencies and better control resolution, critical for applications requiring rapid response to control signals.

How are the control terminals configured?

The module features four control terminals: K1, G1, K2, G2. These enable independent gate triggering of each thyristor in the dual-component design. Power terminals are marked 1 (common anode-cathode), 2 (cathode), and 3 (anode) on the module top.

What protection does the I²t rating provide?

The 1.15kA²·s I²t safety factor indicates short-circuit energy withstand capability. This rating helps determine appropriate fuse and protection device selection to prevent device damage during fault conditions while maintaining system safety.
