BT136X-800E,127

Overview

The BT136X-800E,127 is a four-quadrant sensitive gate 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 peak off-state voltage (VDRM) of 800 V with a maximum off-state leakage current of 100 uA at VDRM. Key electrical parameters include an on-state voltage of 1.5 V, a maximum holding current (Ih) of 15 mA, a gate trigger voltage (Vgt) of 1.5 V, and a gate trigger current (Igt) of 70 mA. It 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 enables direct interface with microcontrollers and logic integrated circuits.
• Four-quadrant triggering ensures reliable operation across all gate polarities.

Applications

• Solid state relays
• Lighting control systems
• Motor speed controllers

Procurement Notes

Verify the specific suffix 'E' against official documentation, as the provided reference data primarily lists the BT136X-800 variant without the E designation. Confirm availability status directly with the manufacturer or authorized distributors, as supply conditions for this specific part number may differ from general family listings. Ensure the ordering code matches the required sensitivity class.

Selection Notes

Select this component when an 800 V blocking voltage is required alongside a 4 A continuous current rating. The sensitive gate characteristic simplifies driver circuit design compared to standard gate devices. Verify that the TO-220FP-3 package dimensions fit the target PCB layout and thermal management requirements for the intended application environment.

Part Context

This device belongs to the BT136 series of triacs, widely used in AC power switching applications. The 'X' prefix typically denotes an insulated or fully encapsulated plastic package variant, while the '800' indicates the 800 V voltage rating. This series is designed for general-purpose phase control and bidirectional switching tasks in consumer and industrial electronics.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent 800 V, 4 A sensitive gate triacs in TO-220FP packages. Verify pinout compatibility and ensure that gate trigger current specifications meet the driving circuit capabilities before substitution.
