The X02 sensitive gate SCR can be used as the on/off function in applications where topology does not offer high current for gate triggering. This device is optimized in forward voltage drop and inrush current capabilities for reduced power losses and high reliability in harsh environments.
The X02 series of sensitive gate Silicon Controlled Rectifiers (SCRs) is designed for applications requiring low gate triggering current, such as ground fault circuit interrupters and overvoltage crowbar protection. The device is optimized for reduced power losses and high reliability in harsh environments due to its low forward voltage drop and high inrush current capabilities.
| On-state rms current | 1.25 A |
|---|---|
| Repetitive peak off-state voltage | 600 V and 800 V |
| Gate triggering current | 50 and 200 µA |
