BT136B-600E,118

Overview

The BT136B-600E,118 is a bidirectional triac manufactured by WeEn Semiconductors, designed for general-purpose switching and phase control applications. It features an RMS on-state current rating of 4 A and supports a non-repetitive peak on-state current of 27 A. The device withstands a rated repetitive off-state voltage (VDRM) of 600 V with a maximum off-state leakage current of 100 uA at VDRM. Key electrical parameters include an on-state voltage of 1.4 V, a maximum holding current of 15 mA, a gate trigger voltage of 700 mV, and a gate trigger current of 11 mA. It operates within a temperature range of -40 C to +125 C and utilizes a D2PAK-3 surface-mount package.

Feature Summary

• Sensitive gate design enabling direct interface with microcontrollers and logic integrated circuits
• Four-quadrant triggering capability for reliable operation in all gate signal polarities
• Glass passivation provides protection against mechanical stress and chemical corrosion

Applications

• General purpose bidirectional switching
• Lighting dimmer circuits
• Solid state relays
• Motor speed control systems

Procurement Notes

Verify the specific suffix '118' corresponds to the tape and reel packaging format when sourcing from distributors. Confirm RoHS compliance status through official manufacturer documentation or component test reports prior to final procurement decisions. Ensure the supplier source is authorized to guarantee authenticity and traceability of the semiconductor components.

Selection Notes

Select this component for designs requiring a compact surface-mount solution with 4 A current handling capabilities. The D2PAK-3 package offers improved thermal performance compared to standard through-hole options while maintaining low gate trigger requirements. Evaluate thermal management strategies based on the specific PCB layout and ambient operating conditions to ensure junction temperatures remain within the specified limits during continuous operation.

Part Context

This part belongs to the BT136 series of sensitive gate triacs produced by WeEn Semiconductors. The series is widely utilized in consumer electronics and industrial control equipment for AC power regulation. The BT136B variant specifically denotes the surface-mount construction, distinguishing it from the through-hole TO-220 variants within the broader product family.

Replacement Considerations

Compatible substitutes include other 4 A, 600 V sensitive gate triacs in SMD packages such as the BTA16 series or equivalent logic-level triacs from other manufacturers. Verify pinout compatibility and thermal resistance characteristics before implementing any cross-brand replacement in existing circuit designs.
