BT136S-600D,118

Overview

The BT136S-600D,118 is a logic-level sensitive gate triac manufactured by WeEn Semiconductors. It features a 600 V rated repetitive off-state voltage and a 4 A RMS on-state current capability. The device supports non-repetitive surge currents of up to 27 A and maintains an on-state voltage of 1.4 V. Gate triggering requires a maximum voltage of 1.5 V and a current of 5 mA. With a maximum holding current of 10 mA, it operates within a junction temperature range extending to +125 °C. The component is housed in a DPAK (TO-252-3) surface-mount package.

Feature Summary

• Logic-level sensitive gate architecture enabling direct interface with microcontrollers and low-power digital logic circuits.
• Four-quadrant sensitivity ensures reliable triggering across all combinations of main terminal and gate polarities.
• Surface-mount DPAK packaging facilitates automated assembly and compact printed circuit board layouts.

Applications

• Domestic lighting dimmers
• Solid state relays
• Motor speed controllers

Procurement Notes

Verify the specific suffix '118' against the manufacturer's official documentation to confirm tape and reel specifications. Ensure compatibility with standard SMD reflow profiles for the DPAK package. Cross-reference the part number with authorized distributors to validate authenticity and traceability before integration into production designs.

Selection Notes

Select this component when a surface-mount solution is required for AC power control applications. The logic gate specification simplifies driver circuit design compared to standard gate devices. Confirm that the 4 A RMS rating meets the load requirements and that the thermal management strategy accommodates the DPAK package's heat dissipation characteristics at the intended operating temperature.

Part Context

This device belongs to the BT136 series of triacs, widely utilized for general-purpose AC switching. The 'S' designation typically indicates a surface-mount variant, while the 'D' suffix denotes the logic-level gate sensitivity. This specific model represents a modernized version of traditional through-hole triacs, adapted for contemporary high-density electronics manufacturing.

Replacement Considerations

Direct replacements include the BT136S-600E,118 and other BT136S-600 variants from WeEn Semiconductors. Equivalent logic-level triacs in DPAK packages from other manufacturers may serve as alternatives if electrical parameters match exactly.
