BT134W-800EF

Overview

The WeEn Semiconductors BT134W-800EF is a four-quadrant triac designed for AC power control applications. It features an RMS on-state current of 1A and supports repetitive peak off-state voltages up to 800V. The device utilizes a glass passivation process for enhanced reliability and is housed in a DPAK surface-mount package, designated by the 'W' suffix. This component provides robust switching capabilities for low-power AC loads.

Feature Summary

• Four-quadrant triggering capability for reliable gate control across all voltage polarities
• Glass-passivated junction construction for improved environmental stability
• Surface-mount DPAK packaging optimized for automated assembly processes

Applications

• Lighting dimmer circuits
• Small motor speed control systems
• Solid-state relay output stages

Procurement Notes

Verify the specific suffix EF against official WeSem datasheets to confirm exact binning or tape-and-reel specifications. Ensure compatibility with standard DPAK footprint requirements during PCB layout. Confirm RoHS compliance status through current manufacturer declarations before final procurement approval.

Selection Notes

Select this component when a 1A RMS current rating and 800V blocking voltage are sufficient for the load. The DPAK package is suitable for applications requiring compact surface-mount solutions. Evaluate thermal management needs based on the expected duty cycle and ambient operating conditions.

Part Context

This part belongs to the BT134 series of four-quadrant triacs from WeEn Semiconductors. The series offers various voltage ratings and package options. The BT134W variant specifically denotes the DPAK surface-mount form factor, distinguishing it from through-hole equivalents like the BT134-600E.

Replacement Considerations

Compatible substitutes include the BT134-800 and BT134W-800 from NXP Semiconductors. Verify pinout compatibility and thermal characteristics when replacing components from different manufacturers.
