Line Thyristor (SKT 40)

Features

- Hermetic metal case with glass insulator
- Threaded stud ISO M8
- International standard case

Typical Applications

- DC motor control (e.g. for machine tools)
- Controlled rectifiers ( e.g. for battery charging)
- AC controllers (e.g. for temperature control)
- Recommended snubber network e.g. for V_VRMS≤400V: R=68Ω/11W, C=0.22μF
