BT138Y-600E,127

Triacs Overview

The BT138Y-600E,127 is a four-quadrant logic level TRIAC manufactured by WeEn Semiconductors. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (IT(RMS)) of 12 A. The device supports a non-repetitive peak on-state current of 105 A with a maximum on-state voltage of 1.4 V. Gate triggering specifications 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 junction temperature range of -40 °C to +125 °C and utilizes a TO-220-3 through-hole package.

Triacs Feature Summary

• Four-quadrant sensitive gate operation for reliable triggering across all AC line polarities
• Logic-level compatibility allowing direct drive from standard digital logic circuits
• High thermal stability supporting continuous operation up to 125 °C junction temperature

Triacs Applications

• Lighting control systems requiring phase-angle dimming
• Solid-state relay modules for industrial switching
• Motor speed control circuits for small appliances

Triacs Procurement Notes

Verify the specific suffix '127' corresponds to the required tape and reel packaging configuration. Confirm RoHS compliance status against the latest manufacturer declaration. Ensure the ordering part number matches the exact voltage and current ratings required for the target circuit design before finalizing procurement orders.

Triacs Selection Notes

Select this component when a 12 A RMS current rating and 600 V blocking voltage are sufficient for the load. The TO-220-3 package requires appropriate heatsinking for high-power applications. Verify that the gate trigger current of 25 mA aligns with the driving circuit's output capabilities to ensure reliable turn-on under all operating conditions.

Triacs Part Context

This part belongs to the BT138 series of four-quadrant TRIACs from WeEn Semiconductors. The series includes variants with different voltage ratings such as the BT138Y-800E. The BT138Y-600E,127 specifically denotes the 600 V version in the TO-220-3 plastic package, distinguishing it from surface-mount or higher voltage alternatives within the same family.

Triacs Replacement Considerations

The BT138-600E,127 serves as a functional equivalent within the same series. Cross-reference with NXP Semiconductors versions if supply chain diversification is required, ensuring pinout and electrical parameters remain compatible.
