Triacs Overview

The BT138-800G,127 is a sensitive gate triac manufactured by WeEn Semiconductors. It features an RMS on-state current of 12 A and a repetitive peak off-state voltage (VDRM) of 800 V. The device has a maximum non-repetitive on-state current of 105 A and an on-state voltage of 1.4 V. Gate triggering parameters include a maximum holding current of 30 mA, a gate trigger voltage of 700 mV, and a gate trigger current of 22 mA. It operates at a maximum temperature of +125 C and uses a TO-220F-3 through-hole package.

Triacs Feature Summary

Sensitive gate design for direct interfacing with logic level ICs
Four-quadrant gate triggering capability
Direct interfacing to low power gate drive circuits

Triacs Applications

General purpose switching
Phase control applications
230 V lamp dimmers

Triacs Procurement Notes

Verify the specific suffix 'G' against official manufacturer documentation to confirm pinout or thermal characteristics compared to standard variants. Ensure the component matches the required RoHS compliance status for your assembly process. Cross-reference the Mouser number 771-BT138X-800127 if sourcing from distributors, noting that part numbers may vary slightly between manufacturers like NXP and WeEn for equivalent specifications.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 12 A continuous current rating are required in a TO-220F-3 package. The sensitive gate characteristic makes it suitable for low-power drive circuits. Verify that the 1.4 V on-state voltage meets the efficiency requirements of the load. Consider the 125 C maximum operating temperature for high-ambient environments.

Triacs Part Context

This triac belongs to the BT138 family of passivated sensitive gate thyristors. The family includes variants with different voltage ratings such as 600 V and 800 V. These devices are designed for general-purpose AC switching and phase control applications. The TO-220F-3 package provides electrical isolation for the case connection.
