This handbook provides detailed specifications for the Microsemi silicon‑controlled rectifiers (SCRs) part numbers 2N1794‑1804 and 2N4371‑4377. It lists electrical characteristics such as on‑state current, voltage ratings, and surge capabilities, as well as thermal and mechanical data needed for design and application.
The document also includes switching, triggering and blocking parameters, typical forward characteristics graphs, and thermal impedance curves to aid engineers in selecting the appropriate device for phase‑control and power‑conversion circuits.
| Max peak on‑state voltage | 1.6 V |
|---|---|
| Mounting torque | 100‑130 in·lb |
| Weight (typical) | 3.24 oz (91.8 g) |
A torque of 100‑130 inch‑pounds is recommended.
