WEEN SEMICONDUCTORS Thyristor, 500V, 200µA, 2.5A, TO-220AB

The WEEN SEMICONDUCTORS Thyristor is a planar passivated Silicon Controlled Rectifier (SCR) featuring a sensitive gate, housed in a robust SOT78 (TO-220AB) plastic package. This device is specifically engineered for direct interfacing with microcontrollers, logic integrated circuits, and other low-power gate trigger circuits, making it an essential component for modern electronic designs.

Its sensitive gate allows for reliable triggering from minimal current, simplifying circuit design and reducing the need for additional driver stages. The planar passivated construction enhances voltage ruggedness and long-term reliability, ensuring stable performance in demanding switching environments.

Ideal Applications

• General Purpose Switching: Perfect for a wide range of AC power control applications.
• Protection Circuits: Used in crowbar and over-voltage protection systems to safeguard sensitive electronics.
• Low-Power Control: Directly triggered by microcontrollers, logic ICs, and other low-power drivers, streamlining design and reducing component count.

With its through-hole mounting (TO-220AB case style), this thyristor offers ease of installation and excellent thermal management via an optional heatsink. Its compact yet durable package is built to withstand high surge currents, providing a dependable solution for both prototyping and production.
