The T435-800B-TR is a high-performance triac from STMicroelectronics, designed for AC power control applications. This triac is a part of the T435 series and is well-suited for a wide range of medium power AC switching applications where high surge capability is required. It is commonly used in applications such as motor control, industrial and domestic lighting, heating, and static switching.

Key Features

• High Blocking Voltage: With an 800V maximum repetitive peak off-state voltage (V_DRM/V_RRM), this triac is capable of handling high voltage applications with ease.
• Current Handling: The T435-800B-TR can conduct up to 4A of continuous on-state current (I_T(RMS)), making it suitable for controlling moderately high power loads.
• High Surge Current: It has a non-repetitive surge peak on-state current (I_TSM) of 40A, which is beneficial for applications requiring high inrush currents.
• Gate Trigger Current: A low gate trigger current (I_GT) makes the triac easy to drive with simple gate circuits.
• Package: Housed in a TO-252 (DPAK) surface-mount package, the T435-800B-TR is suitable for compact designs and ensures efficient thermal management.
