LJ6004V8TP

Triacs Overview

The LJ6004V8TP is a logic-level sensitive gate TRIAC manufactured by Littelfuse, designed for AC power control applications. It features a 600 V non-repetitive peak off-state voltage and supports a maximum RMS on-state current of 4 A. The device utilizes a TO-251AA (IPak) through-hole package with short leads. Key electrical characteristics include a maximum gate trigger voltage of 1.3 V and a maximum gate trigger current of 20 mA. It operates within a junction temperature range of -40°C to 150°C and offers high surge current capability, rated at 40 A for 50 Hz and 48 A for 60 Hz non-repetitive half-sine wave conditions.

Triacs Feature Summary

• Logic-sensitive gate architecture enables direct interface with low-power digital logic circuits without requiring additional drive components.
• High thermal stability allows reliable operation in demanding environments with junction temperatures extending up to 150°C.
• Robust surge handling capacity ensures protection against transient overcurrent events during startup or fault conditions.

Triacs Applications

• Solid-state relays and contactors
• Lighting dimmers and motor speed controls
• Heating element regulation

Triacs Procurement Notes

Verify the specific ordering suffix to confirm package style and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing process. Cross-reference the manufacturer's latest datasheet for any updates on agency approvals such as UL recognition before finalizing procurement.

Triacs Selection Notes

Select this component when a compact TRIAC with logic-compatible gate sensitivity is required for low-to-medium power AC switching. The TO-251AA package is suitable for automated assembly processes. Evaluate the 600 V rating against the peak line voltage plus transients to ensure adequate margin. Confirm that the 4 A RMS current rating exceeds the load requirements under all operating conditions.

Triacs Part Context

This part belongs to the LJxx04xx series of TRIACs from Littelfuse. The series is characterized by its combination of small form-factor packaging and logic-level gate drive capabilities. These devices are engineered to simplify circuit design by reducing the need for complex gate drive networks while maintaining robust performance in standard AC power control topologies.

Triacs Replacement Considerations

Direct replacements must match the 600 V voltage rating, 4 A current rating, and TO-251AA package. Verify that substitute parts also feature logic-sensitive gates to maintain compatibility with existing drive circuitry. Check for identical pinout configurations to ensure mechanical interchangeability without PCB modifications.
