Product Description
STMicroelectronics T405-600B is a surface mount TRIAC with 3 terminals designed for AC power control and switching applications. It is rated for a repetitive peak reverse voltage of 600 V and an average on-state current of 4 A, making it suitable for medium power industrial and consumer electronic circuits.
This TRIAC package type TO-252 enables low-profile mounting on printed circuit boards (PCBs), ideal for power regulation in motor controls, lighting dimmers, heating elements, and other automation controls.
The gate trigger voltage of 1.3 V and maximum gate trigger current of 5 mA allow precise and sensitive triggering to reduce switching losses. The device withstands surge current spikes up to 31 A and has a peak gate power dissipation rating of 1 W, ensuring reliable operation under transient conditions.
Operating temperature capability from -40°C to 125°C makes the T405-600B suitable for harsh industrial environments and automotive applications where extreme temperatures are encountered.
The TRIAC's low repetitive peak off-state current of 5 microamps minimizes power waste in the off state, contributing to overall system efficiency. With compact dimensions (6.6 mm length and 2.4 mm height), it accommodates high-density PCB layouts.
Rated average on-state current: 4 A. Package type: TO-252 surface mount. Gate trigger voltage: 1.3 V. Maximum gate current: 5 mA. Surge current rating: 31 A. Operating temperature range: -40°C to 125°C. Peak gate power dissipation: 1 W.
Repetitive peak reverse voltage: 600 V. Repetitive peak off-state current: 5 μA. Compact footprint: 6.6 mm length, 2.4 mm height.
This TRIAC is widely used in industrial power control, heating, lighting, motor speed control, home appliances, and HVAC systems. It offers robust electrical performance combined with a versatile surface mount package, enabling efficient and reliable power switching solutions.
