BT137S-800E
4Q Triac
12 October 2016 Product data sheet
1. General description
Planar passivated sensitive gate four quadrant triac in a SOT428 (DPAK) surface-mountable
plastic package intended for use in 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.
2. Features and benefits
• 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
• Surface-mountable package
• Triggering in all four quadrants
3. Applications
• General purpose motor controls
• General purpose switching
