Overview
The BT134W-600E,115 is a planar passivated sensitive gate four-quadrant triac manufactured by WeEn Semiconductors. It operates in a SOT-223 (SC-73) surface-mount package with four pins. Key electrical parameters include a rated repetitive peak off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 1 A. The device supports a non-repetitive peak on-state current of 11 A and maintains a maximum holding current of 15 mA. Gate triggering requirements specify a maximum voltage of 700 mV and current of 30 mA across all quadrants. The component functions within a junction temperature range of -40 °C to +125 °C.
Feature Summary
- Sensitive gate architecture designed for direct interfacing with low-power drivers such as microcontrollers.
- Planar passivation technology ensures robust performance and reliability under industrial conditions.
- Four-quadrant operation capability allows reliable triggering regardless of the polarity of the main terminal voltage or gate signal.
Applications
- Lighting control systems requiring low-power interface compatibility.
- Solid-state relays utilizing surface-mount assembly processes.
- General-purpose AC power switching applications in consumer electronics.

Selection Notes
Select this component when a surface-mount TRIAC with sensitive gate characteristics is required for low-current AC switching. The 1 A RMS rating suits light loads, while the 600 V blocking voltage provides adequate margin for standard single-phase mains applications. Ensure the PCB layout accommodates the SOT-223 thermal dissipation needs.
Part Context
This part belongs to the BT134W series of sensitive gate triacs from WeEn Semiconductors. The series is characterized by its integration into compact surface-mount packages, facilitating automated assembly. The BT134W-600E variant specifically denotes the 600 V blocking voltage class within this family, distinguishing it from higher voltage counterparts like the 800 V versions.
Replacement Considerations
Direct pin-compatible replacements within the same package and electrical class should be verified against official substitution lists. Cross-reference with other manufacturers' SOT-223 sensitive gate triacs only if datasheet parameters for VDRM, IT(RMS), and IGT are strictly matched.
