L4004V8TP

Triacs Overview

The Littelfuse L4004V8TP is a four-quadrant sensitive gate triac belonging to the Teccor Lxx04xx series. It features a TO-220AB (TO-220-2) package and supports a repetitive peak off-state voltage of 400 V with a root-mean-square on-state current rating of 4 A. The device exhibits a holding current of 5 mA, a latching current of 5 mA, and a gate trigger current of 5 mA. Its maximum on-state voltage is 1.6 V, while the maximum non-repetitive peak on-state current reaches 40 A. The component operates within a junction temperature range of -40 °C to +125 °C.

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and thermal characteristics. Ensure the selected variant matches the required voltage and current ratings for the target circuit design before finalizing procurement.

Triacs Selection Notes

Select this component when a 4 A load capacity and 400 V blocking capability are required in a TO-220 package. Confirm that the 5 mA gate sensitivity aligns with the available drive signal strength in the application circuit.

Triacs Part Context

This part belongs to the Teccor Lxx04xx family of 4 Amp sensitive and standard triacs. These devices are engineered for general-purpose AC power switching applications requiring robust performance in compact packages.

Triacs Replacement Considerations

Consult Littelfuse cross-reference guides for verified substitutes. Generic replacements must match the 400 V rating, 4 A current capacity, and TO-220-2 package form factor.
