Q6004D4TP

Triacs Overview

The Littelfuse Q6004D4TP is a bidirectional triac from the Teccor Qxx04xx series, designed for general-purpose AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (It RMS) 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 of 30 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 25 mA to 50 mA. It exhibits a typical on-state voltage of 1.6 V and a maximum off-state leakage current of 10 µA at VDRM. The component is housed in a surface-mount TO-252-3 package.

Triacs Feature Summary

• Surface-mount TO-252-3 package design facilitates automated PCB assembly and compact layout integration.
• High thermal stability supports reliable operation across extended industrial temperature ranges up to 125°C.
• Robust 600 V blocking capability ensures safe handling of standard AC line voltages in power circuits.

Triacs Applications

• Solid-state relay modules requiring compact switching elements
• Lighting dimmer circuits for residential and commercial fixtures
• Motor speed control systems for small appliances

Triacs Procurement Notes

Verify the specific suffix 'D4' against official Littelfuse documentation to confirm the exact pinout configuration and packaging type. Ensure the ordering quantity aligns with manufacturer reel specifications. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.

Triacs Selection Notes

Select this component when a surface-mount solution is required for 4 A AC loads. Compare the 600 V rating against peak line voltages to ensure adequate margin. Evaluate the gate trigger current requirements of the driving circuitry to ensure compatibility with available logic levels or driver outputs.

Triacs Part Context

This part belongs to the Littelfuse Teccor Qxx04xx family of triacs. The series provides standardized performance for low-to-medium power AC switching. The Q6004D4TP specifically adapts these characteristics for surface-mount technology, distinguishing it from through-hole variants like the Q6004V4TP while maintaining similar electrical ratings.

Triacs Replacement Considerations

Direct replacements must match the 600 V / 4 A rating and TO-252-3 footprint. Verify equivalent gate sensitivity and thermal resistance. Consult Littelfuse substitution guides for cross-brand equivalents that meet identical JEDEC outline dimensions.
