BT138X-600D,127

Triacs Overview

The BT138X-600D,127 is a four-quadrant Triac manufactured by WeEn Semiconductors. It features an RMS on-state current of 12 A and a non-repetitive peak on-state current of 105 A. The device supports a rated repetitive peak off-state voltage (VDRM) of 600 V with a maximum off-state leakage current of 100 uA at VDRM. On-state voltage is specified at 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 within a temperature range of -40°C to +125°C and utilizes a TO-220FP-3 through-hole package.

Triacs Feature Summary

• Four-quadrant sensitivity for reliable triggering across all gate polarities
• High thermal stability supporting operation up to +125°C junction temperature
• Robust construction designed for high surge current handling capabilities

Triacs Applications

• General purpose AC power control circuits
• Lighting dimmer applications
• Motor speed control systems

Triacs Procurement Notes

Verify the complete part number including the suffix ,127 to ensure correct packaging configuration. Confirm RoHS compliance status via official documentation prior to integration. Check for any Product Change Notifications that may affect pinout or material composition. Ensure the supplier provides valid traceability data for quality assurance purposes.

Triacs Selection Notes

Select this component when a 12 A RMS current rating and 600 V blocking voltage are required in a TO-220FP-3 package. Compare gate trigger current specifications against driver capabilities to ensure adequate switching margin. Evaluate thermal management requirements based on the 1.4 V on-state voltage drop under load conditions.

Triacs Part Context

This Triac belongs to the BT138X series from WeEn Semiconductors, designed for general-purpose AC switching. It shares functional similarities with other devices in the BT138 family but offers specific electrical characteristics tailored for medium-power applications. The component serves as a solid-state alternative to mechanical relays in AC control scenarios.

Triacs Replacement Considerations

Direct substitutes include the BT138X-600 and BT138-600/DG,127. Verify pin compatibility and thermal resistance values before substitution. Ensure the replacement device meets the same 12 A RMS and 600 V VDRM ratings.
