Overview
The SCA240DA160 is a thyristor module from SanRex Corporation featuring a 1600 V repetitive peak off-state voltage and an average on-state current rating of 240 A at Tc=86°C. It supports a non-repetitive surge current of 6000/6500 A (50/60Hz) and offers a critical di/dt of 500 A/µs. The device utilizes a compact package with unique heat dissipation technology, providing low thermal resistance (0.105 °C/W junction-to-case). It includes isolation breakdown voltage of 3000 V AC and operates within a junction temperature range of -40°C to 125°C.
Feature Summary
- Unique heat dissipation technology enables high current capacity in a standard package size.
