WEEN SEMICONDUCTORS Thyristor 400V 50µA 500mA TO-92 3 Pins

The WEEN SEMICONDUCTORS Thyristor is a high-performance semiconductor device designed for low power applications requiring reliable switching and voltage ruggedness. Featuring planar passivation, this thyristor ensures excellent reliability and durability, making it a dependable choice for sensitive electronic circuits.

Equipped with a very sensitive gate, this component operates efficiently with a gate trigger current of just 50µA and a gate trigger voltage of 800mV. It supports a peak repetitive off-state voltage of 400V and an average on-state current of 500mA, with an on-state RMS current of 800mA. The device can handle a peak non-repetitive surge current of 8A and has a maximum holding current of 1mA.

This component is specifically suited for use in ignition circuits, low power latching circuits, and various protection or shut-down circuits for lighting ballasts and Switched Mode Power Supplies (SMPS).

Designed for through-hole mounting, this thyristor comes in a compact TO-92 case style with 3 pins, making it highly suitable for dense circuit board layouts. It operates reliably at temperatures up to 125°C. The component measures 43 mm in height, 33 mm in width, and 15 mm in depth, with a lightweight profile of just 0.091 grams.
