BT139B-600E,118

Triacs Overview

The BT139B-600E,118 is a logic level triac manufactured by WeEn Semiconductors. It features an RMS on-state current of 16 A and a rated repetitive off-state voltage (VDRM) of 600 V. The device supports a non-repetitive peak on-state current of 170 A with a maximum on-state voltage of 1.2 V. Gate triggering requirements include a maximum gate trigger voltage (Vgt) of 700 mV and a maximum gate trigger current (Igt) of 25 mA. The component operates within a temperature range of -40°C to +125°C and is housed in a D2PAK-3 surface mount package.

Triacs Feature Summary

• Logic level sensitivity for direct microcontroller interfacing
• High thermal stability across extended industrial temperature ranges
• Robust surge handling capability for inductive loads

Triacs Applications

• Solid state relays
• Industrial motor control circuits
• Lighting dimmer applications

Triacs Procurement Notes

Verify the specific suffix '118' against official manufacturer documentation to confirm tape and reel specifications. Ensure compatibility with standard SMD reflow profiles for the D2PAK-3 package. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Triacs Selection Notes

Select this component when high current switching is required in a compact surface-mount form factor. The logic level gate drive simplifies circuit design by reducing the need for complex driver stages. Verify that the 600 V blocking voltage meets the system's peak line voltage requirements.

Triacs Part Context

This part belongs to the BT139 series of four-quadrant logic level triacs from WeEn Semiconductors. The series is designed for general purpose AC power control applications. The 'B' grade typically indicates specific voltage and current characteristics within the family lineup.

Triacs Replacement Considerations

Compatible replacements include the BT139B-600,127 (TO-220 package) or other BT139 variants with matching 600 V ratings and 16 A current capabilities. Verify pinout and thermal resistance differences when substituting packages.
