BT139B-600F,118

Triacs Overview

The BT139B-600F,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 non-repetitive peak surge current rating of 170 A. It features a rated repetitive peak off-state voltage of 600 V and a maximum gate trigger current of 50 mA across quadrants Q1, Q2, and Q3. The component operates within a junction temperature range up to 125 °C and includes a dV/dt rating of 200 V/µs.

Triacs Feature Summary

• Planar passivated construction for enhanced reliability
• Four-quadrant logic level triggering capability
• Surface-mountable D2PAK package design

Triacs Applications

• Motor control systems
• Industrial static switching
• Domestic lighting regulation
• Heating element control

Triacs Procurement Notes

Verify the specific suffix 'F' against official manufacturer documentation to confirm pinout and electrical tolerances, as variations exist within the BT139 series. Ensure the ordering part number matches the required packing configuration, typically reel format for this package type. Cross-reference the 12NC code for accurate supply chain tracking and compliance verification.

Triacs Selection Notes

Select this component when a surface-mount TRIAC with 16 A continuous current handling is required. The 600 V blocking voltage suits standard AC line applications. Verify that the D2PAK thermal performance meets the system's heat dissipation requirements. Confirm compatibility with the driving circuit's gate trigger current limits, which max at 50 mA for this variant.

Triacs Part Context

This part belongs to the BT139 series of glass or planar passivated triacs from WeEn Semiconductors. The series offers various voltage ratings and packages. The BT139B-600F specifically denotes the 600 V rating and D2PAK surface-mount form factor. It serves as a solid-state alternative to mechanical relays in AC power control circuits.

Triacs Replacement Considerations

Compatible substitutes include the BT139B-600G,118, which shares the same electrical specifications and package but may differ in packaging details. Other variants like BT139X-600 offer similar performance in different packages. Always verify pinout compatibility before substitution.
