BT131-600EQP

Overview

The BT131-600EQP is a four-quadrant logic level triac manufactured by WeEn Semiconductors, designed for AC power switching applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 1 A. The device operates with a maximum junction temperature of +125°C and includes a gate trigger voltage (VGT) of up to 700 mV and a gate trigger current (IGT) of 3.8 mA. It utilizes a TO-92 plastic package and exhibits a holding current (IH) of 5 mA maximum.

Feature Summary

• Four-quadrant sensitivity enables reliable triggering across all gate polarities and main terminal voltages.
• Logic-level gate design allows direct interfacing with low-power microcontrollers and digital logic circuits.
• High thermal stability supports operation at junction temperatures up to +125°C.

Applications

• AC motor speed control
• Lighting dimmer circuits
• Solid-state relays

Procurement Notes

Verify the specific suffix EQP against official WeSem datasheets to confirm packaging and environmental compliance details. Ensure the component matches the required pinout and thermal characteristics for the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when a 600 V blocking voltage and 1 A continuous current are sufficient for the load. The logic-level gate sensitivity makes it suitable for systems driven by 3.3 V or 5 V microcontrollers without additional driver stages.

Part Context

This part belongs to the BT131 series of four-quadrant triacs, originally developed by NXP Semiconductors and now produced by WeEn Semiconductors. The series is widely used in consumer electronics for phase control applications requiring robust AC switching capabilities.

Replacement Considerations

Direct replacements include BT131-600, BT131-600/DG, and BT131-600E variants from WeEn or NXP. Cross-brand alternatives such as L601E3 from Littelfuse may be considered if pin compatibility and electrical ratings align.
