Q8004V3TP

Triacs Overview

The Littelfuse Q8004V3TP is a bidirectional triac designed for power control applications. It features an RMS on-state current rating of 4 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device operates within a temperature range of -40 °C to +125 °C and utilizes a TO-252-3 surface-mount package. Key electrical parameters include a maximum holding current of 30 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 25 mA. The peak on-state voltage is specified at 1.6 V, with a non-repetitive peak on-state current capability ranging from 46 A to 55 A.

Triacs Feature Summary

• High-voltage blocking capability suitable for demanding AC power switching environments
• Surface-mount construction optimized for automated PCB assembly processes
• Sensitive gate triggering characteristics enabling direct interface with logic-level drivers

Triacs Applications

• Solid-state relay modules requiring high isolation and compact form factors
• Industrial motor speed control circuits operating at elevated voltages
• Lighting dimmer systems for commercial or industrial fixtures

Triacs Procurement Notes

Verify the specific suffix 'V3TP' against the manufacturer's latest datasheet to confirm pinout orientation and thermal pad configuration. Ensure that the ordering documentation explicitly references the Teccor brand family specifications to avoid confusion with similar high-voltage triacs in the Qxx04 series. Cross-reference the RoHS compliance status directly with the official Littelfuse component database prior to finalizing procurement orders.

Triacs Selection Notes

Select this component when circuit designs require an 800 V blocking voltage combined with a 4 A continuous load capacity in a surface-mount footprint. Evaluate the thermal management requirements carefully, as the TO-252-3 package relies on PCB copper area for heat dissipation. Confirm that the gate drive circuit can supply the necessary 25 mA trigger current under all expected operating temperature conditions to ensure reliable turn-on.

Triacs Part Context

This part belongs to the Littelfuse Qxx04xx series of high-voltage triacs, marketed under the Teccor brand. The series is engineered for robust performance in AC power control applications where high voltage isolation is critical. The Q8004V3TP specifically addresses the need for surface-mount solutions in industrial equipment, replacing older through-hole alternatives while maintaining comparable electrical ratings.

Triacs Replacement Considerations

Direct substitutes within the same series include the Q8004D3RP and Q8004D4TP. Verify package compatibility and gate sensitivity differences before substitution. The D3RP variant uses a reel package, while the D4TP shares the tube packaging style.
