LX807DTRP

Triacs Overview

The Littelfuse LX807DTRP is a bidirectional triac from the LX8 series, designed for surface-mount applications in the SOT-223-4 package. It features an RMS on-state current of 800 mA and a rated repetitive off-state voltage of 400 V. The device supports a non-repetitive peak on-state current of 9.5 A with a maximum holding current of 5 mA. Gate triggering parameters include a voltage of 1.3 V and currents ranging from 5 mA to 7 mA. It operates within a temperature range of -40°C to +110°C junction temperature, with an on-state voltage of 1.6 V and a leakage current of 5 µA at VDRM.

Triacs Feature Summary

• Sensitive gate logic enables reliable triggering with low gate current requirements.
• Surface-mount SOT-223-4 packaging facilitates automated assembly and compact board design.
• High thermal stability supports operation up to 110°C junction temperature.

Triacs Applications

• Lighting control circuits
• Solid-state relays
• Motor speed control

Triacs Procurement Notes

Verify the specific suffix DTRP confirms the SOT-223-4 surface-mount package and 400V rating against the official Littelfuse datasheet. Confirm RoHS compliance status as indicated in manufacturer documentation. Ensure ordering quantities align with reel or cut-tape availability constraints specified by authorized distributors.

Triacs Selection Notes

Select this component when a 400V rated triac is required for surface-mount designs. Compare the 800mA RMS current capability against load requirements. Verify that the sensitive gate characteristics match the driving circuit's output capabilities. Consider the SOT-223-4 thermal dissipation limits for the intended application environment.

Triacs Part Context

This part belongs to the Littelfuse LX8 series of thyristors. It shares core electrical specifications with other LX8 variants but differs in packaging and voltage ratings. The DTRP suffix specifically denotes the surface-mount configuration, distinguishing it from through-hole equivalents like the LX807DE or LX807MEAP which utilize TO-92 packages.

Triacs Replacement Considerations

Direct substitutes include other LX8 series triacs with identical 400V and 800mA ratings if pin compatibility allows. Cross-reference package dimensions for SOT-223-4 alternatives from other manufacturers only if electrical parameters match exactly.
