L4004D6RP

Triacs Overview

The L4004D6RP is a four-quadrant sensitive gate triac manufactured by Littelfuse, designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (IT(RMS)) of 4 A. The device guarantees gate control in Quadrants I, II, III, and IV, with a maximum gate trigger current (IGT) of 10 mA. Key electrical parameters include a holding current (IH) of 10 mA, a gate trigger voltage (VGT) of 2 V, and an on-state voltage of 1.6 V. It operates within a junction temperature range of -40°C to +110°C and is housed in a TO-252-3 surface-mount package.

Triacs Feature Summary

• Four-quadrant gating capability ensures reliable control using digital circuitry with positive or negative pulses.
• Sensitive gate design allows for low-power triggering with a maximum gate trigger current of 10 mA.
• Glass-passivated junctions provide long-term device reliability and parameter stability under thermal stress.

Triacs Applications

• Lighting dimmers and soft-start circuits
• Solid-state relays and motor speed controls
• General AC power switching in consumer appliances

Triacs Procurement Notes

Verify the specific suffix 'RP' against the manufacturer's official datasheet to confirm the reel packaging configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the Mouser part number 576-L4004D6RP for accurate distributor availability and lead times. Confirm that the TO-252-3 footprint matches your PCB design guidelines before finalizing procurement.

Triacs Selection Notes

Select this component when a 400 V rating and 4 A continuous current are required in a compact surface-mount form factor. The four-quadrant sensitivity makes it suitable for logic-level interface applications where minimal gate drive current is necessary. Compare the IT(RMS) and surge current capabilities against the load profile to ensure adequate safety margins during startup transients.

Triacs Part Context

This device belongs to the Teccor line of sensitive gate triacs from Littelfuse. The L4004 series offers current capabilities ranging from 0.8 A to 8 A with voltage ratings up to 600 V. The L4004D6RP specifically utilizes a surface-mount TO-252-3 package, distinguishing it from through-hole variants like the L4004F62 while maintaining similar electrical characteristics.

Triacs Replacement Considerations

The L4004D6TP is a pin-compatible alternative in the same series but uses tube packaging instead of a reel. Verify that the packaging difference does not impact automated pick-and-place operations. Other L4004 series devices may require re-evaluation of current ratings and package types.
