Q6004L4TP

Triacs Overview

The Littelfuse Q6004L4TP is a Teccor Quadrac device, which integrates a triac and a diac trigger within a single package. It operates as a bidirectional AC switch with gate control for either polarity of main terminal voltage. The component features an on-state RMS current capacity of 4 A and a rated repetitive off-state voltage (VDRM) of 600 V. It utilizes a TO-220-3 package style for through-hole mounting. Key electrical parameters include a holding current maximum of 30 mA, a gate trigger voltage (VGT) of 2.5 V, and gate trigger currents ranging from 25 mA to 50 mA. The device supports non-repetitive on-state currents of 46 A and 55 A, with an operating temperature range from -40°C to +125°C.

Triacs Feature Summary

• Integrated Diac Trigger: Combines a triac and diac in one package to eliminate discrete assembly and reduce cost.

Triacs Applications

• AC switching and phase control applications
• Speed controls
• Temperature modulation controls
• Lighting controls requiring noise immunity

Triacs Procurement Notes

Verify the specific suffix 'L4TP' against the manufacturer's official datasheet to confirm pinout configuration and packaging details. Ensure compatibility with the intended thermal management requirements for the TO-220-3 package. Confirm RoHS compliance status via the latest regulatory documentation provided by Littelfuse before finalizing procurement specifications.

Triacs Selection Notes

Select this component when design constraints require integrated noise immunity and simplified circuit topology for AC phase control. The integrated diac eliminates the need for external snubber networks or separate diac components. Verify that the 4 A RMS current rating meets the load requirements and that the 600 V blocking voltage is sufficient for the target AC line voltage.

Triacs Part Context

This part belongs to the Teccor brand Quadrac series developed by Littelfuse. These devices are designed to save assembly time and expense by integrating the trigger mechanism directly into the triac package. The series offers various current capacities and voltage ratings, providing electrically isolated solutions suitable for high-reliability AC power control applications.

Triacs Replacement Considerations

Direct substitutes may include other Quadrac devices from the same family with matching current and voltage ratings, such as the Q6010L4TP for higher current needs. Cross-brand replacements require careful verification of pinout compatibility, gate trigger characteristics, and thermal performance to ensure equivalent functionality in the existing circuit design.

Triacs FAQ

Does the Q6004L4TP require an external snubber network?

No, the Quadrac device design eliminates the need for a snubber network, simplifying the circuit layout.

What is the isolation capability of the TO-220 package?

The TO-220 package provides electrical isolation of 2500 V rms from the leads to the mounting surface.

How does the integrated diac benefit the application?

It saves the user the expense and assembly time of buying a discrete diac and assembling it with a gated triac.
