SM2LZ47,Bi-Directional Triode Thyristor,TO-220F-3

The SM2LZ47 is a bi-directional triode thyristor (Triac) developed by Toshiba for AC power control applications. With an 800V repetitive peak off-state voltage (VDRM) and a continuous on-state current rating of 2A, it is designed for reliable and efficient operation in industrial automation, motor control, and lighting dimmer circuits.

Featuring a low gate trigger voltage (Vgt) of 1.5V and a trigger current (Igt) of 10mA, the SM2LZ47 is optimized for sensitive gate triggering, allowing easy control via low-power logic circuits. Its ability to handle high surge currents (ITSM of 8.8A at 60Hz) ensures stable operation under varying load conditions.

The TO-220F-3 package provides excellent thermal management and electrical insulation, making it suitable for applications requiring compact yet powerful switching components. With a high dv/dt capability (5V/µs min), the SM2LZ47 offers superior noise immunity and high-speed switching characteristics.
