BT134W-600,135

Overview

The BT134W-600,135 is a sensitive gate four-quadrant triac manufactured by WeEn Semiconductors. It features 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 surge current of 11 A with a maximum on-state voltage of 1.2 V. Gate triggering requirements include a maximum voltage of 700 mV and current of 30 mA across all quadrants. It operates within a junction temperature range of -40°C to +125°C and is housed in a SOT-223-4 surface-mount package.

Feature Summary

• Sensitive gate architecture designed for direct interfacing with low-power logic drivers and microcontrollers.
• Four-quadrant operation capability ensuring reliable triggering regardless of MT2 polarity or gate signal polarity.
• Planar passivated construction provides robust protection against mechanical stress and environmental factors.

Applications

• Lighting control circuits for residential and commercial LED dimmers
• Solid-state relay inputs requiring low drive power
• General-purpose AC load switching in consumer appliances

Procurement Notes

Verify the specific suffix '135' against official manufacturer documentation, as standard listings often utilize suffixes like '115' or 'E'. Confirm RoHS compliance status and lead-free conversion dates directly from the supplier's certificate of conformity. Ensure the ordering part number matches the exact tape-and-reel specifications required for automated assembly processes.

Selection Notes

Select this component when a surface-mount solution is required for low-current AC switching applications. The 1 A RMS rating suits light loads, while the 600 V blocking voltage handles standard mains voltages. Consider the SOT-223-4 package for space-constrained PCB designs where thermal dissipation needs are moderate. Verify that the gate trigger current aligns with the driving circuit's output capabilities.

Part Context

This triac belongs to the BT134 series of sensitive gate thyristors. It shares functional similarities with through-hole variants but offers a surface-mount footprint for modern manufacturing. The device is part of WeEn Semiconductors' portfolio of general-purpose power control components derived from legacy NXP designs.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific model variant are not available in the provided reference data. Engineers should consult official cross-reference guides for equivalent devices such as the BT134W-600,115 or BT134-600G,127, verifying pinout and electrical parameter compatibility before substitution.
