Sensitive Gate Thyristor, 100 V, 8 A, TO-220AB Package
Stock Quantity: 0
The MCR72-3G is a sensitive gate thyristor manufactured by LITTELFUSE. This silicon controlled rectifier (SCR) is designed for applications requiring moderate current control with low gate trigger current. It features a repetitive peak off-state voltage of 100V and a continuous on-state current rating of 8A. The MCR72-3G is packaged in a TO-220AB through-hole mounting configuration.
The MCR72-3G thyristor is commonly used in circuits that require switching and phase control of AC power. Its sensitive gate characteristic makes it suitable for applications where low-current control signals are present. Typical deployments include:
