Littelfuse Sensitive Gate Silicon Controlled Rectifier 600 V, 0.8 A, 8 A Surge Current, 200 μA Gate Trigger Current MCR08BT1G

Littelfuse MCR08BT1G Sensitive Gate Silicon Controlled Rectifier (SCR) is a robust semiconductor device designed for phase control applications requiring precise triggering and reliable conduction characteristics.

Encapsulated in a compact and surface-mount SOT-223 package, this SCR operates with a repetitive peak reverse voltage (VDRM) of 600 V and supports an average on-state current of 0.8 A with surge capability up to 8 A, making it suitable for industrial and electronic control circuits.

The device features a gate trigger current of 200 μA for sensitive gate activation, allowing it to operate efficiently with low power input. It includes a 4-pin design, which facilitates easy mounting on printed circuit boards, enhancing integration in compact designs.

Its operating temperature range from -40°C to 110°C enables dependable performance across diverse industrial environments, including power electronics, motor control, and HVAC systems.

This SCR is used in solid-state power control circuits where bistable switching and forward bias conduction are required. The low peak on-state voltage of 1.7 V ensures reduced power dissipation during operation. Its repetitive peak off-state current of 200 μA guarantees minimal leakage, improving overall circuit efficiency.

The maximum holding current of 5 mA supports stable device turn-off behavior. The surface mount mounting type aligns with modern automated assembly processes.

Whether for industrial equipment, laboratory apparatus, or commercial electronic applications, the Littelfuse MCR08BT1G offers reliable and efficient performance. Ideal for replacing or upgrading existing SCRs in sensitive gate switching applications.
