BT131W-600,135

Overview

The BT131W-600,135 is a planar passivated sensitive gate four-quadrant triac manufactured by WeEn Semiconductors. It is housed in an SOT-223 (SC-73) surface-mount package designed for direct interfacing with logic-level ICs and low-power gate drivers. Key electrical parameters include a rated repetitive 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 13.8 A. Gate trigger specifications feature a maximum gate trigger voltage (VGT) of 700 mV and a maximum gate trigger current (IGT) of 3.8 mA. The component operates at a maximum junction temperature of +125°C.

Feature Summary

• Sensitive gate design enabling direct connection to microcontrollers and low-power logic circuits
• Four-quadrant triggering capability for reliable AC switching across all phase angles
• Planar passivation technology ensuring high voltage ruggedness and long-term reliability

Applications

Selection Notes

Select this component when a surface-mount TRIAC with sensitive gate characteristics is required for low-power AC control. Ensure the circuit design accommodates the 600 V blocking voltage and 1 A RMS current limits. Verify that the PCB footprint matches the SOT-223 package dimensions and that thermal management supports operation up to 125°C junction temperature.

Part Context

This part belongs to the BT131 series of four-quadrant TRIACs originally developed by NXP Semiconductors. Following the spin-off of NXP's standard products division, manufacturing and sales rights were transferred to WeEn Semiconductors. The BT131W variant specifically denotes the surface-mountable SOT-223 package configuration within this established product family.
