Littelfuse Silicon Controlled Rectifier SCR 50 V 12 A TO-220AB Package MCR68-2G

Littelfuse MCR68-2G is a high-performance silicon controlled rectifier (SCR) thyristor designed for power electronics applications requiring robust phase control and switching capability. It supports a repetitive peak reverse voltage of 50 V and a rated average on-state current of 12 A, making it suitable for medium power loads in industrial and commercial electronics.

This component is housed in a TO-220AB package, which provides excellent thermal dissipation in through-hole mounting formats. The device can handle surge currents up to 100 A, enabling it to tolerate sudden overloads or transients without damage.

The gate trigger current of 30 mA and holding current of 50 mA facilitate reliable triggering and stable conduction during operation. Designed to operate in harsh environments, it withstands temperatures from -40°C up to a maximum operating temperature of 125°C.

Other electrical characteristics include a repetitive peak off-state current of 2 mA, ensuring low leakage in off-state, and a peak on-state voltage of 2.2 V for efficient current conduction. While it carries no specific automotive standards, its solid-state construction ensures durable performance in various industrial, manufacturing, and HVAC control circuits.

Phase control thyristor for power regulation applications. High surge current rating supports transient overloads. Standard through-hole mounting with 3-pin configuration. Wide operating temperature range from -40°C to 125°C.
