BT1308W-600D,135

Overview

The BT1308W-600D,135 is a bidirectional thyristor (TRIAC) manufactured by WeEn Semiconductors. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (It RMS) of 800 mA. The device supports a non-repetitive peak on-state current of 10 A. Key electrical parameters include a maximum holding current of 10 mA, a gate trigger voltage of 900 mV, and a gate trigger current of 4 mA. The component operates within a temperature range of -40°C to +125°C and utilizes an SOT-223-4 surface-mount package.

Feature Summary

• Sensitive gate design enabling direct interfacing with logic level integrated circuits
• Four-quadrant gate triggering capability for reliable switching in AC applications
• Passivated structure housed in a surface-mountable plastic package

Applications

• General purpose switching and phase control
• Low-power AC fan speed controllers

Procurement Notes

Verify the specific suffix '135' against official manufacturer documentation to confirm packaging details, as standard listings often reference '115'. Ensure compliance with RoHS and REACH requirements by checking the latest product data sheet. Confirm that the ordering information matches the required tape and reel specifications for automated assembly processes.

Selection Notes

Select this component for low-power AC load control where sensitive gate drive compatibility is required. The 600 V rating suits general mains voltage applications. Verify that the 800 mA RMS current capacity meets the continuous load requirements. Consider the SOT-223-4 package dimensions for PCB layout constraints and thermal management needs during operation.

Part Context

This part belongs to the BT1308W series of logic-level TRIACs from WeEn Semiconductors. The series includes variants with different voltage ratings, such as the 400 V version. These devices are designed for applications requiring direct interface with microcontrollers or low-power drivers, offering a balance between commutation performance and gate sensitivity in a compact surface-mount form factor.

Replacement Considerations

Check for cross-reference availability with other manufacturers offering similar 600 V, 800 mA TRIACs in SOT-223 packages. Verify pinout compatibility and electrical parameter equivalence before substitution.
