Q4N4RP

Triacs Overview

The Littelfuse Q4N4RP is a bidirectional triac in the Qxx06xx series, rated for 400V repetitive off-state voltage and 6A RMS on-state current. It utilizes an SMTO-263-2 surface-mount package with a maximum operating temperature of +125°C. Key electrical parameters include a 1.6V on-state voltage, 50µA leakage current at VDRM, and a holding current of up to 50mA. Gate triggering requires between 2.5V and 25mA to 50mA. The device supports non-repetitive peak currents of 65A or 80A and is designed for robust AC switching applications.

Triacs Feature Summary

• Integrated gate control for reliable AC phase switching
• Surface-mount construction for automated assembly
• High thermal stability for elevated ambient conditions

Triacs Applications

• AC motor speed controls
• Lighting dimmer circuits
• Temperature modulation systems

Triacs Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure correct gate sensitivity and packaging type. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Check for active production status and lead times directly with authorized distributors to avoid obsolete stock.

Triacs Selection Notes

Select this component when a 400V rating and 6A continuous current capacity are required in a compact SMD form factor. Ensure the gate drive circuit can supply the specified 25mA to 50mA trigger current. Compare against similar series members if different holding currents or package styles are needed for the specific PCB layout constraints.

Triacs Part Context

This part belongs to the Teccor Qxx06xx family of high-performance triacs manufactured by Littelfuse. These devices are engineered for general-purpose AC power control where reliability and low on-state voltage are critical. The Q4N4RP specifically offers a balance of moderate current handling and standard voltage blocking in a widely used surface-mount footprint.

Triacs Replacement Considerations

Direct substitutes within the same voltage and current class include the Q4006N4RP. Verify pinout compatibility and thermal resistance values before swapping. Alternative packages may require schematic redesign.
