Overview
The BT131-800EQP is a standard triac manufactured by WeEn Semiconductors, designed for AC power control applications. It features an RMS on-state current (ItRMS) of 1 A and a non-repetitive peak on-state current (Itsm) of 13.8 A. The device supports a rated repetitive peak off-state voltage (VDRM) of 800 V, with a maximum off-state leakage current of 100 uA at VDRM. Key gate parameters include a maximum gate trigger voltage (VGT) of 700 mV and a maximum gate trigger current (IGT) of 3.8 mA. The on-state voltage is specified at 1.2 V, while the holding current (Ih) maximum is 5 mA. Operating temperature ranges from -40°C to +125°C.
Feature Summary
- Standard triac configuration for general-purpose AC switching
- High thermal stability with operation up to +125°C junction temperature
- Robust blocking capability with 800 V repetitive peak off-state voltage rating
Applications
- Lighting dimmers
- Motor speed controls
- Heating element regulation
Procurement Notes
Verify the specific suffix EQP against official manufacturer documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints and reflow profiles. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.
Selection Notes
Select this component when a 1 A RMS current rating and 800 V blocking voltage are required in a compact form factor. Compare gate sensitivity requirements against the 3.8 mA IGT specification. Evaluate thermal management needs given the 125°C maximum operating temperature limit for the intended application environment.
Part Context
This part belongs to the BT131 series of standard triacs from WeEn Semiconductors. The series offers various voltage ratings and packaging options. The BT131-800 variant specifically denotes the 800 V blocking voltage class within this family, providing a balance of current handling and voltage resilience for mid-power AC control tasks.
Replacement Considerations
Consult official substitution guides for equivalent parts with matching ItRMS, VDRM, and package dimensions. Verify that alternative components meet the same gate trigger current and voltage specifications to ensure circuit compatibility without redesign.
