WEEN SEMICONDUCTORS 4Q Triac 800V 8A TO-220AB

The WEEN SEMICONDUCTORS 4Q Triac is a planar passivated sensitive gate four quadrant triac housed in a SOT78 plastic package (TO-220AB). It is specifically designed for general purpose bidirectional switching and phase control applications. This sensitive gate "series E" triac is intended to be interfaced directly to microcontrollers, logic integrated circuits, and other low power gate trigger circuits.

Key Features

• Direct triggering from low power drivers and logic ICs
• High blocking voltage capability
• Low holding current for low current loads and lowest EMI at commutation
• Planar passivated for voltage ruggedness and reliability
• Sensitive gate
• Triggering in all four quadrants

With a peak repetitive off-state voltage of 800V and an on-state RMS current of 8A, this triac provides robust performance for demanding applications. It features a maximum gate trigger voltage of 1V and a peak non-repetitive surge current of 71A, ensuring reliable operation under various conditions. The through-hole mounting style and 3-pin configuration facilitate straightforward installation. The component operates at temperatures up to 125°C and has compact dimensions of 43 mm x 33 mm x 15 mm, weighing just 3.175 grams, making it suitable for space-constrained designs within the BT137 product range.
