L6004D6RP

Triacs Overview

The Littelfuse L6004D6RP is a four-amp sensitive gate triac designed for AC power control applications. It features a rated repetitive off-state voltage of 600 V and an RMS on-state current of 4 A. The device operates within a junction temperature range of -40°C to +110°C and utilizes a TO-252AA (DPAK) surface-mount package. Key electrical characteristics include a maximum holding current of 5 mA, a gate trigger current of 3 mA, and a peak non-repetitive on-state current capability of 33 A or 40 A depending on the specific datasheet variant.

Triacs Feature Summary

• Sensitive gate structure enabling reliable triggering with low gate drive currents
• High thermal stability supporting operation in elevated temperature environments up to 110°C
• Robust surge current handling capability for protecting against transient load conditions

Triacs Applications

• Lighting dimmers and soft-start circuits
• Solid-state relays and motor speed controls
• General-purpose AC power switching modules

Triacs Procurement Notes

Verify the specific suffix configuration against the manufacturer's latest datasheet to ensure compatibility with required sensitivity levels and packaging formats. Confirm RoHS compliance status and lead times directly with authorized distributors prior to ordering. Ensure storage conditions adhere to moisture sensitivity level requirements for surface-mount devices.

Triacs Selection Notes

Select this component when a compact surface-mount solution is required for moderate current AC loads. The 600V rating suits standard single-phase mains applications. Compare the 3mA gate trigger requirement against microcontroller output capabilities to determine if additional driver circuitry is necessary for optimal switching performance.

Triacs Part Context

This part belongs to the Teccor Lxx04xx series of thyristors from Littelfuse. The series provides standardized solutions for consumer and industrial AC control. The DPAK package allows for automated assembly and efficient heat dissipation relative to through-hole alternatives in similar power classes.

Triacs Replacement Considerations

Direct pin-compatible substitutes may include other 4A/600V triacs in TO-252 packages from manufacturers such as STMicroelectronics or Vishay. Verify that gate sensitivity and voltage ratings match exactly to avoid circuit malfunction.
