L4006D8RP

Triacs Overview

The Littelfuse L4006D8RP is a bidirectional triac designed for power control applications. It features an RMS on-state current (It RMS) of 6 A and a rated repetitive peak off-state voltage (VDRM) of 400 V. The device has a maximum holding current (Ih) of 20 mA and operates within a temperature range of -40°C to +110°C. Key electrical parameters include a gate trigger voltage (Vgt) of 2 V, with gate trigger currents (Igt) specified at 10 mA and 20 mA. Non-repetitive on-state currents are rated at 50 A and 60 A, while the on-state voltage is 1.6 V and leakage current is 20 uA.

Triacs Feature Summary

• Sensitive gate structure allowing direct interfacing with microprocessors
• Surface mount construction in TO-252-3 package for automated assembly
• High surge current capability for robust circuit protection

Triacs Applications

• AC motor speed control circuits
• Solid state relay designs
• Lighting dimmer modules

Triacs Procurement Notes

Verify the specific suffix RP indicates reel packaging when sourcing components. Confirm RoHS compliance status through official Littelfuse documentation prior to integration. Ensure the supplier provides valid traceability data matching the manufacturer part number L4006D8RP to prevent counterfeit substitution.

Triacs Selection Notes

Select this component for applications requiring 400 V blocking voltage and 6 A continuous current handling. The sensitive gate characteristics simplify driver circuit design compared to standard gate devices. Verify thermal management requirements align with the TO-252-3 package capabilities for the intended operating environment.

Triacs Part Context

This triac belongs to the Lxx06xx series from Littelfuse, which focuses on surface mount power control solutions. The series offers various current ratings tailored for compact electronic designs. The L4006D8RP specifically addresses needs for moderate power switching in space-constrained PCB layouts.

Triacs Replacement Considerations

Cross-reference with other Littelfuse L4006 variants if different packaging options are required. Verify pinout compatibility before substituting with equivalent triacs from other manufacturers.
