MOC3021 White Optocoupler (ON) DIP-6 Code: 83600590

The MOC3021 is a 6-pin random-phase phototriac optocoupler. It safely isolates low-voltage DC control circuits (like microcontrollers) from high-voltage AC lines (up to 400V), commonly serving as a driver to trigger larger power TRIACs in AC dimmers, motor speed controllers, and solid-state relays.

Key Specifications

• Isolation Voltage:5000 Vrms (input to output)
• Peak Output Voltage :400 V
• Trigger LED Current:15 mA (maximum to latch output)
• Peak Output Current:1 A (pulse width 1 ms)
• Operating Temperature:-40°C to +85°C

Pinout Configuration

1. Anode:LED positive terminal
2. Cathode:LED negative terminal
3. NC:No internal connection
4. Main Terminal 2 (MT2):Triac side (connects to AC load/TRIAC main terminal)
5. Substrate:Do not connect (often left floating)
6. Main Terminal 1 (MT1):Triac side (triggers main TRIAC gate)
