BT152-800R,127 Thyristor, 800V, 32mA, 13A, 20A, TO-220AB

The BT152-800R,127 from WEEN SEMICONDUCTORS is a high-performance planar passivated silicon controlled rectifier (SCR) designed for demanding electronic applications. Housed in a robust 3-pin TO-220AB through-hole package, this thyristor is engineered to deliver exceptional reliability and ruggedness in circuits that experience high inrush currents and significant thermal stress.

A key feature of this component is its very high current surge capability, peaking at 220A, making it exceptionally robust against transient overloads. It boasts an 800V repetitive peak off-state voltage and an 800V repetitive peak reverse voltage, providing a high voltage capability essential for protection and regulation circuits. With a 20A RMS on-state current and a 13A average on-state current, it is built to handle substantial power loads efficiently.

The planar passivated construction enhances voltage ruggedness and long-term reliability, while its high thermal cycling performance ensures stable operation in environments with fluctuating temperatures, up to a maximum of 125°C. The device requires a maximum gate trigger voltage of 1.5V and a maximum gate trigger current of 32mA for switching, with a holding current of up to 60mA.

Typical Applications

This thyristor is ideally suited for a variety of power control and protection scenarios, including:

• Ignition circuits in automotive or industrial systems.
