BT1308W-600D,115

Overview

The BT1308W-600D,115 is a sensitive gate 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 800 mA. The device supports a non-repetitive surge current (ITSM) of 10 A. Key electrical parameters include a maximum holding current (Ih) of 10 mA, a gate trigger voltage (VGT) of 900 mV, and a gate trigger current (IGT) of 4 mA. The on-state voltage is specified at 1.35 V, with a leakage current of 100 uA under VDRM conditions. It operates within a temperature range of -40 C to +125 C and is housed in a SOT-223-4 surface-mount package.

Feature Summary

• Sensitive gate design enabling direct interfacing with logic level ICs and low-power gate drive circuits.
• Four-quadrant gate triggering capability for reliable switching performance across all input polarities.
• Passivated structure housed in a surface-mountable plastic package designed for increased heatsink efficiency.

Applications

• General purpose switching applications
• Phase control circuits
• Low-power AC fan speed controllers

Procurement Notes

Verify the manufacturer part number against official WeEn Semiconductors documentation to ensure authenticity. Confirm that the ordering suffix matches the required packaging configuration. Check for any recent Product Change Notifications regarding material or process updates. Ensure compliance with RoHS and REACH standards as specified in the latest datasheet. Validate component markings against the physical package to prevent counterfeit risks.

Selection Notes

Select this component when a surface-mount TRIAC with high gate sensitivity is required for microcontroller-driven loads. The 600 V rating suits standard AC line voltages. Verify that the 800 mA RMS current meets the load requirements. Consider the thermal management capabilities of the SOT-223 package for the specific application environment. Ensure the gate drive circuit can supply the necessary trigger current without exceeding limits.

Part Context

This device belongs to the BT1308W Series D TRIAC family from WeEn Semiconductors. It shares the same package and general characteristics as the BT1308W-400D variant, differing primarily in the breakdown voltage rating. The series is designed for logic-level interface applications requiring compact surface-mount solutions for AC power control tasks.

Replacement Considerations

The BT1308W-400D is a confirmed substitute within the same series, offering identical package and functional characteristics with a lower voltage rating of 400 V. Verify that the reduced voltage rating is acceptable for the target AC line voltage before substitution.
