STMicroelectronics Surface Mount 3-Pin TRIAC 600V Rated Average On-State Current 12A T1250-600G-TR

STMicroelectronics T1250-600G-TR is a robust surface mount TRIAC with a 3-pin configuration, designed for efficient control of AC power in industrial, consumer electronics, and automation applications. This device features a rated average on-state current (Irms) of 12 A and a repetitive peak reverse voltage (VDRM) rating of 600 V, making it suitable for medium power switching tasks.

The TRIAC operates reliably in temperatures ranging from -40°C to 125°C, supporting long-term durability in demanding electrical environments. It is housed in a TO-263 package with a compact footprint measuring 10.28 mm in length and 4.6 mm in height, facilitating integration into high-density circuit assemblies.

Advantages include a low gate trigger voltage of 1.3 V and gate trigger current of 50 mA, allowing for low power control signal requirements. The high surge current rating of 126 A enables the device to handle transient overloads effectively.

This TRIAC’s maximum holding current of 50 mA and minimal repetitive peak off-state current of 5 μA reduce power dissipation and enhance efficiency. The peak on-state voltage of 1.55 V limits conduction losses under load.

STMicroelectronics implements strict quality measures to ensure compliance with semiconductor performance standards, though this model does not carry specific industrial certifications or automotive standards.

Ideal use cases include industrial machinery control, HVAC equipment switching, lighting controls, and other AC power modulation applications requiring reliable, compact, and efficient TRIAC solutions.
