L4004V6

Triacs Overview

The L4004V6 is a four-quadrant logic level TRIAC from the Teccor sensitive gate series, manufactured by Littelfuse. It features a rated repetitive off-state voltage (VDRM) of 400 V and an RMS on-state current (ITRMS) of 4 A. The device operates within a junction temperature range of -40 °C to +125 °C. Key electrical parameters include a maximum holding current (Ih) of 5 mA, a gate trigger voltage (VGT) of 2 V, and a gate trigger current (IGT) of 3 mA. The typical on-state voltage is 1.6 V, with an off-state leakage current of 5 µA. It is housed in a TO-251-3 (SOT-89) surface-mount package.

Triacs Feature Summary

• Four-quadrant gating capability ensures reliable control in Quadrants I, II, III, and IV, allowing digital circuitry to manage AC current direction with positive or negative pulses.
• Sensitive gate design enables direct interface with low-power logic circuits through guaranteed low gate trigger current and voltage specifications.
• Glass-passivated junction construction provides long-term device reliability and parameter stability under varying thermal conditions.

Triacs Applications

• Control circuits for small AC motors requiring precise logic-level triggering
• Solid-state relays utilizing compact surface-mount packaging
• Lighting dimmer applications compatible with standard TRIAC topologies

Triacs Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm pinout orientation and thermal characteristics. Ensure the procurement channel sources components directly from authorized distributors to guarantee authenticity. Confirm RoHS compliance status matches the project requirements before finalizing orders.

Triacs Selection Notes

Select this component when a compact SOT-89 footprint is required for 4 A AC switching applications. The sensitive gate specification allows for direct driving from microcontrollers without additional buffer transistors. Verify that the 400 V voltage rating meets the peak line voltage requirements of the target AC load circuit.

Triacs Part Context

This part belongs to the Lxx04xx series of sensitive gate TRIACs produced by Littelfuse under the Teccor brand. The series offers various voltage ratings and package options, ranging from through-hole TO-220 variants to surface-mount configurations like the TO-251-3 used in this model.

Triacs Replacement Considerations

Direct replacements must match the 4 A current rating, 400 V blocking voltage, and SOT-89 package. Verify that substitute devices also offer four-quadrant sensitivity and comparable gate trigger currents to ensure circuit compatibility.
