BT131-600,412

Overview

The BT131-600,412 is a four-quadrant logic level Triac manufactured by WeEn Semiconductors. It features a rated repetitive peak off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 1 A. The device supports a non-repetitive peak on-state current of 13.7 A and maintains a maximum holding current (IH) of 5 mA. Gate triggering specifications include a gate trigger voltage (VGT) of 700 mV and a gate trigger current (IGT) of 3.8 mA. The component operates within a junction temperature range up to +125 °C and utilizes a TO-92-3 through-hole package.

Feature Summary

• Four-quadrant logic level operation for reliable triggering across all gate polarities
• High thermal stability with a maximum operating junction temperature of +125 °C
• Sensitive gate design enabling direct interface with standard logic circuits

Applications

• Lighting control systems including dimmers and switches
• Solid-state relays requiring low gate drive power
• General-purpose AC load switching applications

Procurement Notes

Verify the specific suffix '412' against official manufacturer documentation to confirm tape-and-reel packaging requirements. Ensure compatibility with RoHS directives if environmental compliance is mandatory for the target assembly. Cross-reference datasheet revisions to validate electrical parameters before finalizing procurement orders.

Selection Notes

Select this component when a 1 A RMS current rating and 600 V blocking voltage are sufficient for the application. The TO-92-3 package is suitable for through-hole mounting processes. Consider the 3.8 mA gate trigger current to ensure the driving circuit can provide adequate gate current under all operating conditions.
