L0107DTRP

Triacs Overview

The Littelfuse L0107DTRP is a sensitive gate bidirectional triac in the L01 series, designed for AC power control applications. It features a 400 V rated repetitive off-state voltage (VDRM) and conducts an RMS on-state current (It RMS) of 1 A. The device exhibits a low on-state voltage of 1.6 V and a maximum holding current of 10 mA. Gate triggering requirements are specified with a voltage (Vgt) of 1.3 V and a current (Igt) ranging from 5 mA to 7 mA. Non-repetitive peak on-state currents reach 10 A or 12 A depending on conditions. Leakage current is limited to 5 uA at VDRM. It operates within a temperature range of -40 C to +125 C and is housed in an SOT-223-4 surface-mount package.

Triacs Feature Summary

• Sensitive gate architecture enables reliable triggering with low gate drive power requirements.
• Robust thermal performance supports operation across extended industrial temperature ranges.
• Compact surface-mount packaging facilitates automated assembly and space-constrained PCB layouts.

Triacs Applications

• AC motor speed control circuits
• Solid-state relay output stages
• Lighting dimmer switches

Triacs Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Littelfuse or authorized distributors before integration. Confirm that the SOT-223-4 footprint matches your PCB design guidelines. Ensure supply chain sources are authorized to guarantee component authenticity and traceability for critical power control designs.

Triacs Selection Notes

Select this part when a 400 V blocking voltage and 1 A continuous current rating are sufficient for the load. Compare against the L0107MEAP if through-hole TO-92 packaging is preferred instead of surface mount. Verify that the sensitive gate characteristics align with the available gate drive circuitry in the target application design.

Triacs Part Context

This component belongs to the Littelfuse L01 series of thyristors, which focuses on general-purpose AC switching solutions. The DTRP suffix indicates the specific surface-mount SOT-223-4 package configuration and reel packaging format, distinguishing it from leaded variants within the same electrical family.

Triacs Replacement Considerations

The L0107MEAP serves as a functional equivalent with identical electrical specifications but utilizes a TO-92 through-hole package. Substitution requires verifying mechanical fit and soldering process compatibility. No other direct cross-model substitutes are confirmed in public documentation.
