BT139B-600G,118

Triacs Overview

The BT139B-600G,118 is a planar passivated four-quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO263 (D2PAK) surface-mountable plastic package designed for high bidirectional transient and blocking voltage capability. The device supports an RMS on-state current of 16 A with a rated repetitive peak off-state voltage of 600 V. Maximum gate trigger currents are specified at 50 mA for quadrants Q1, Q2, and Q3, and 100 mA for quadrant Q4. The component operates within a junction temperature range up to 125°C and features a critical rate of rise of off-state voltage of 200 V/us.

Triacs Feature Summary

• Four-quadron logic level triggering capability for versatile gate drive compatibility
• Planar passivation technology ensuring robust performance under high thermal cycling conditions
• Surface-mount D2PAK package optimized for industrial and domestic static switching applications

Triacs Applications

• Motor control systems
• Industrial lighting regulation
• Domestic heating controls
• Static switching circuits

Triacs Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and packing configuration. Ensure that the selected variant matches the required surface-mount footprint and reel specifications for automated assembly processes. Cross-reference the part number with current RoHS compliance records to meet regulatory standards.

Triacs Selection Notes

Select this component when a surface-mount TRIAC with 16 A continuous current handling is required. The 600 V blocking voltage rating suits standard AC line applications. Verify that the gate drive circuit can supply the maximum 100 mA trigger current needed for quadrant 4 operation to ensure reliable turn-on across all voltage polarities.

Triacs Part Context

This part belongs to the BT139 series of glass or planar passivated triacs originally developed by Philips Semiconductors. WeEn Semiconductors continues production of these legacy devices. The BT139B-600G variant specifically denotes the 600 V version in the D2PAK package, distinguishing it from higher voltage ratings or through-hole packages within the same family.

Triacs Replacement Considerations

Compatible substitutes include the BT139B-600E,127 in a TO-220 package for through-hole designs. For direct surface-mount replacement, verify pinout compatibility with other D2PAK TRIACs offering identical 16 A and 600 V ratings.
