Overview
The BT134W-600,115 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. The device supports an RMS on-state current of 1 A and a non-repetitive peak on-state current of 11 A. It features a rated repetitive peak off-state voltage of 600 V and a maximum off-state leakage current of 100 uA at VDRM. The on-state voltage is specified at 1.2 V. Gate triggering requirements include a maximum voltage of 700 mV and a maximum current of 30 mA across all quadrants. The component maintains a maximum holding current of 15 mA and functions within a 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 passivated construction ensures robust performance and reliability in surface-mount applications.
Applications
- Lighting control systems requiring low-power interface compatibility
- General-purpose AC load switching circuits
- Solid-state relay implementations
Procurement Notes
Verify the specific ordering suffix to confirm packaging configuration, as variants exist with different reel specifications. Confirm RoHS compliance status through official documentation prior to integration. Ensure the selected part number matches the required tape and reel format for automated assembly processes. Cross-reference the manufacturer's latest datasheet to validate any recent process change notifications or material updates affecting the component.
Selection Notes
Select this component when a surface-mount TRIAC with sensitive gate characteristics is required for microcontroller-driven applications. The 1 A RMS rating suits moderate power loads, while the 600 V blocking voltage provides adequate margin for standard AC line voltages. Consider the SOT-223 package constraints for thermal management and PCB layout space compared to through-hole alternatives.
Part Context
This part belongs to the BT134W series of sensitive gate triacs from WeEn Semiconductors. It shares functional similarities with other devices in the family but differs in packaging and specific electrical tolerances. The '115' suffix typically denotes a specific tape and reel packing option for volume manufacturing.
Replacement Considerations
Direct replacements include the BT134W-600E,115, which offers identical electrical characteristics and pinout within the same SOT-223 package. Verify that substitute parts maintain the sensitive gate specification to ensure compatibility with existing low-current drive circuits without modification.
