BT138X-600F,127

Triacs Overview

The BT138X-600F,127 is a glass passivated bidirectional triac manufactured by WeEn Semiconductors. It features an RMS on-state current of 12 A and a non-repetitive peak on-state current of 95 A. The device supports a rated repetitive off-state voltage (VDRM) of 600 V with a maximum leakage current of 100 uA at VDRM. Key electrical parameters include a gate trigger voltage of 1.5 V and a gate trigger current of 70 mA. The holding current maximum is 20 mA, and the on-state voltage is 1.65 V. It operates within a temperature range of -40 C to +125 C and is housed in a TO-220FP-3 through-hole package.

Triacs Feature Summary

• Glass passivation for enhanced reliability under high thermal cycling conditions
• Rail packaging format for efficient automated assembly
• High bidirectional transient and blocking voltage capability

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix '127' corresponds to rail packaging when sourcing. Confirm RoHS compliance status via official documentation. Check for recent Product Change Notifications that may affect pinout or material composition. Ensure the supplier provides valid traceability data for industrial applications.

Triacs Selection Notes

Select this component for applications requiring 12 A continuous current handling in a TO-220FP-3 package. Compare gate trigger requirements against driver capabilities, as the 70 mA gate current is higher than standard logic-level devices. Consider thermal management solutions given the 125 C maximum junction temperature rating.

Triacs Part Context

This part belongs to the BT138X series of four-quadrant triacs from WeEn Semiconductors. It shares core specifications with variants like BT138X-600D but differs in packaging and specific test conditions. The series is designed for general-purpose AC power control applications requiring robust performance.

Triacs Replacement Considerations

Direct substitutes include BT138X-600D,127 and BT138-600/DG,127. Verify package compatibility and gate sensitivity differences before substitution. Cross-reference with BT137S-600F for similar voltage ratings but different current capabilities.
