STMicroelectronics T835H-8T Triac

The T835H-8T is a high-performance triac manufactured by STMicroelectronics, designed to cater to a wide range of AC power control applications. This triac is part of the STMicroelectronics snubberless high-temperature series, which is known for its robust performance in challenging environments.

The T835H-8T is capable of handling up to 8A RMS with a maximum peak repetitive off-state voltage (VDRM/VRRM) of 800V, making it suitable for the on/off or phase angle control in applications such as motor control, lighting control, and static relays. Its high commutation capabilities allow it to be used in circuits where high surge currents are prevalent, ensuring reliability and longevity of the device.

One of the key features of the T835H-8T is its high junction temperature capability, rated at 150°C. This allows for a stable performance even at elevated temperatures, reducing the need for additional cooling systems and simplifying the design of thermal management. The package is also insulated to a voltage of 2500V RMS, providing excellent isolation from the AC line.

The triac comes in a D2PAK package, which is suitable for surface mount technology (SMT). This package type is beneficial for compact designs, offering a space-saving solution without compromising on power handling. It is also characterized by low gate triggering current (IGT), which can improve the efficiency of the control circuitry.

Additionally, the T835H-8T features high noise immunity and dV/dt capability, ensuring that the device is less susceptible to unintended turn-ons due to voltage transients on the AC line. This makes the T835H-8T a reliable choice for applications that are sensitive to electrical noise.

Overall, the STMicroelectronics T835H-8T triac is an excellent choice for designers looking for a high-performing, durable, and efficient solution for controlling AC power in various industrial and consumer applications.
