2P4M SCR THYRISTOR

🔹 2P4M SCR Thyristor – 2A Sensitive Gate, TO-202 / TO-126 Package

The 2P4M is a sensitive-gate silicon-controlled rectifier (SCR) designed for low-power AC switching applications. It is commonly used in motor speed controls, lamp dimmers, temperature regulators, and battery chargers .

✅ Specifications:

Repetitive Peak Off-State Voltage (VDRM): 400V – 600V (varies by manufacturer)

RMS On-State Current (IT(RMS)): 2A – 4A (varies by package)

Surge Current (ITSM): 20A

Gate Trigger Current (IGT): 200µA max

Gate Trigger Voltage (VGT): 0.8V max

Holding Current (IH): 5mA max

Package: TO-202 / TO-126 (through-hole) or SOT-89 (SMD)

Pinout: Pin 1 = Cathode (K), Pin 2 = Anode (A), Pin 3 = Gate (G)
