LJ4006D8RP

Triacs Overview

The Littelfuse LJ4006D8RP is a bidirectional triac designed for AC 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 600 V. The device exhibits a maximum on-state voltage of 1.6 V and a gate trigger voltage (Vgt) of 2 V, with a gate trigger current (Igt) ranging from 10 mA to 20 mA. Leakage current at VDRM is specified at 20 uA. It operates within a temperature range of -40°C to +150°C and is housed in a TO-252-3 surface-mount package.

Triacs Feature Summary

• Provides reliable AC switching capability with a 6 A continuous current rating suitable for moderate power loads.
• Engineered for high-voltage isolation with a 600 V blocking capability to withstand standard line voltages.
• Utilizes a compact surface-mount TO-252-3 package to facilitate automated assembly and space-constrained PCB designs.

Triacs Applications

• Solid-state relays requiring compact form factors
• General-purpose AC motor speed control circuits
• Lighting dimmer modules for residential or commercial fixtures

Triacs Procurement Notes

Verify the specific suffix 'RP' against official Littelfuse documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure that the ordering information matches the exact electrical characteristics listed in the datasheet, as suffixes can denote variations in packaging or testing criteria rather than functional differences.

Triacs Selection Notes

Select this component when a 6 A RMS current capacity and 600 V blocking voltage are required in a surface-mount configuration. Compare the 1.6 V on-state voltage drop against thermal management requirements for the specific load. Verify that the gate drive circuitry can supply the necessary 10-20 mA trigger current reliably across the full operating temperature range.

Triacs Part Context

This part belongs to the LJxx06xx series of triacs from Littelfuse, which are characterized by their sensing gate structure. This series is distinct from higher current variants like the LJ4008D8TP, offering a balance between current handling and package size for general industrial and consumer AC control tasks.

Triacs Replacement Considerations

Direct substitutes include other 6 A, 600 V triacs in TO-252 packages such as the STMicroelectronics BTA16 series or ON Semiconductor TRIACs. Verify pinout compatibility and ensure that gate sensitivity parameters match the existing driver circuit design before substitution.
