BT138X-800F,127

Triacs Overview

The BT138X-800F,127 is a glass passivated 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 repetitive peak off-state voltage of 800 V with a maximum off-state leakage current of 100 uA at VDRM. Key electrical parameters include a gate trigger voltage of 700 mV and a gate trigger current of 22 mA. The component operates within a temperature range of -40 C to +125 C and utilizes a TO-220FP-3 package for through-hole mounting.

Triacs Feature Summary

• Glass passivation provides high bidirectional transient and blocking voltage capability.
• Full pack plastic envelope design ensures high thermal cycling performance.
• Sensitive gate architecture allows direct interfacing with logic level ICs.

Triacs Applications

• Motor control systems
• Industrial static switching
• Domestic lighting applications

Triacs Procurement Notes

Verify the specific suffix 'F' against official manufacturer documentation to confirm the exact voltage rating and parameter set, as datasheets may vary between series variants. Ensure the ordering part number matches the required package type and compliance standards before finalizing procurement orders.

Triacs Selection Notes

Select this component when high bidirectional blocking voltage and thermal stability are required. The 800 V rating suits higher voltage AC applications compared to lower-rated variants. Verify that the 12 A RMS current capacity meets the load requirements and that the TO-220FP-3 package fits the available PCB space and thermal management strategy.

Triacs Part Context

This device belongs to the BT138X series of glass passivated triacs designed for robust industrial and domestic applications. The series offers various voltage ratings, with the 800 F variant providing enhanced blocking capabilities. It serves as a reliable solution for phase control and switching tasks requiring high reliability under thermal stress.

Triacs Replacement Considerations

Compatible substitutes include the BT138Y-800E,127 and other BT138 series variants from NXP or WeEn Semiconductors. Verify that replacement parts match the 12 A current rating, 800 V blocking voltage, and TO-220FP-3 package dimensions to ensure mechanical and electrical compatibility.
