Q6004R4TP

Triacs Overview

The Littelfuse Q6004R4TP 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 temperature range of -40°C to +125°C and utilizes a TO-251-3 (SOT-923) surface-mount package. Key electrical characteristics 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. The on-state voltage is specified at 1.6 V, with a non-repetitive peak on-state current capability of 46 A or 55 A depending on pulse duration.

Triacs Feature Summary

• Bidirectional switching capability for AC load control
• Surface-mount TO-251-3 package for automated assembly
• High thermal stability up to 125°C junction temperature
• Low gate trigger sensitivity for efficient driver interfacing

Triacs Applications

• Lighting dimmers and soft starters
• Solid-state relays (SSRs)
• Motor speed control circuits
• Heating element regulation

Triacs Procurement Notes

Verify the specific suffix 'R4TP' against the manufacturer's official datasheet to confirm tape-and-reel packaging and exact gate current grades. Ensure compatibility with existing PCB footprints for the TO-251-3 package. Confirm RoHS and REACH compliance status through the latest Littelfuse documentation before finalizing procurement specifications.

Triacs Selection Notes

Select this component when a compact surface-mount solution is required for 600V AC applications. Compare the 4A RMS rating against the expected load current, accounting for derating at elevated temperatures. Verify that the gate drive circuit can supply the specified 25-50 mA trigger current reliably across the full operating temperature range.

Triacs Part Context

This part belongs to the Littelfuse Teccor Qxx04xx family of high-performance triacs. The series is characterized by robust dv/dt ratings and reliable commutation capabilities. The Q6004R4TP specifically targets applications requiring small form-factor packaging while maintaining standard 600V blocking voltage and 4A current handling capabilities typical of the 04xx current class.

Triacs Replacement Considerations

Direct pin-compatible replacements within the same package may include other Q6004 variants with different suffixes indicating distinct packaging or gate sensitivities. Cross-reference with competitors offering TO-251-3 triacs rated at 600V/4A, ensuring identical pinout configuration and comparable thermal resistance values.
