WEEN SEMICONDUCTORS BT134 Series D Triac, 600V, 4A, SOT-82, Through Hole

The WEEN SEMICONDUCTORS BT134 Series D Triac is a planar passivated, very sensitive gate four-quadrant triac in a compact SOT-82 plastic package. Designed for general-purpose bidirectional switching and phase control, this triac is ideal for applications where high sensitivity is required across all four quadrants. Its very sensitive gate allows direct interfacing to microcontrollers, logic integrated circuits, and other low-power gate trigger circuits, simplifying your design and reducing component count.

This 'Series D' triac offers a high blocking voltage capability of 600V and a low holding current, making it suitable for low-current loads and ensuring the lowest EMI at commutation. The planar passivated construction provides voltage ruggedness and reliability, while triggering in all four quadrants offers design flexibility. The through-hole mounting (SOT-82 package) is easy to handle and solder, suitable for a wide range of PCB layouts.

With an on-state RMS current of 4A and a peak non-repetitive surge current of 27A, this triac is a robust choice for controlling AC loads. The maximum gate trigger voltage is 1V, and the maximum holding current is 10mA. It operates at temperatures up to 125°C and features a peak on-state voltage of 1.7V.
