MOC3021 Description

Short technical summary and product information.

The ON Semiconductor MOC3021 is a single-channel optocoupler featuring a Triac driver output. It provides a high isolation voltage of 5000Vrms, making it suitable for applications requiring electrical isolation between control and load circuits.

 

Key electrical specifications include a repetitive peak off-state voltage (VDRM) of 400V and a forward current of 50mA. The device has a high critical rate of rise of off-state voltage (dV/dt) of 1000V/µs. It operates without a zero-crossing circuit.

 

This optocoupler is housed in a standard 6-DIP package and is designed for Through Hole mounting. The operating temperature range is from -40°C to +100°C. It is compliant with RoHS3 standards and has an MSL rating of 1 Unlimited.
