BT136X-800,127

Overview

The BT136X-800,127 is a bidirectional triac manufactured by WeEn Semiconductors. It features an RMS on-state current of 4 A and a non-repetitive peak on-state current of 27 A. The device supports a rated repetitive off-state voltage (VDRM) of 800 V with a maximum off-state leakage current of 100 uA at VDRM. Key electrical parameters include a maximum holding current of 15 mA, a gate trigger voltage of 1.5 V, and a gate trigger current of 70 mA. The component operates within a temperature range of -40 C to +125 C and utilizes a TO-220FP-3 through-hole package.

Feature Summary

• Sensitive gate design for reliable triggering in all four quadrants
• Glass passivation for enhanced environmental protection
• High thermal stability suitable for demanding switching applications

Applications

• General purpose bidirectional switching
• Phase control circuits
• Lighting dimmer applications

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when an 800 V blocking voltage is required alongside a 4 A continuous current rating. Ensure the driving circuit can supply at least 70 mA gate current to guarantee turn-on under worst-case conditions. Verify that the TO-220FP-3 package dimensions fit the available PCB space and thermal management strategy.

Part Context

This part belongs to the BT136X series of sensitive gate triacs from WeEn Semiconductors. It shares the same physical package and general functional architecture as other variants in the family but is distinguished by its specific 800 V voltage rating. The series is designed for robust performance in AC power control environments.

Replacement Considerations

Check datasheets for equivalent parts offering identical 800 V ratings and 4 A current capabilities. Confirm pinout compatibility with the TO-220FP-3 package before substitution.
