The S21MD4V Optocoupler is a high-performance phototriac coupler designed for reliable and efficient switching in medium to high-power applications. It integrates a gallium arsenide infrared LED with a silicon phototriac driver and a built-in zero-crossing circuit to minimize electrical noise during operation. Encased in a compact DIP-6 package, the S21MD4V is optimized for driving AC loads, making it ideal for motor controls, industrial automation, and temperature regulation systems.

The device supports a wide operating temperature range and a high isolation voltage of 5000 Vrms, ensuring safe and durable performance in demanding environments. Its zero-crossing functionality further enhances its suitability for inductive and resistive loads, offering a versatile solution for a range of industrial and consumer applications.

Key Features :
  • Zero-Crossing Circuitry: Built-in zero-crossing feature ensures smooth and noise-free switching.
  • High Blocking Voltage: Rated at a repetitive peak off-state voltage of 600V, suitable for high-voltage applications.
  • Enhanced Isolation: Provides 5000 Vrms isolation voltage for safe and reliable operation.
  • Compact DIP-6 Package: Easy integration into PCB designs with through-hole mounting.
  • Wide Operating Temperature Range: Reliable performance from -30C to +100C.
  • High Surge Current Capability: Handles up to 1.2A peak surge current for robust operation.
