NEC 3P4M Thyristor 3A 400V TO-202AA
NEC 3P4M Thyristor 3A 400V TO‑202AA is a silicon controlled rectifier (SCR) designed for controlled rectification and switching applications in power electronics. This three‑terminal semiconductor device utilizes a P‑gate fully diffused SCR structure to provide reliable turn‑on control of AC or DC power circuits with an average on‑state current of up to 3 A and a repetitive peak off‑state voltage of 400 V. It is housed in a compact TO‑202AA through‑hole package, suitable for traditional PCB assembly and rugged enough for various industrial environments.
Features
- P-gate fully diffused construction for high sensitivity.
- 400 V repetitive peak off-state voltage rating.
- 3 A average on-state current with 4.7 A RMS capability.
- Extremely low gate trigger current of maximum 0.2 mA.
