Q2025NH6RP

Triacs Overview

The Littelfuse Q2025NH6RP is a bidirectional triac designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (IT(RMS)) of 25 A. The device operates within a temperature range of -40 °C to +125 °C. Key electrical parameters include a maximum holding current of 100 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 80 mA. It exhibits an on-state voltage of 1.8 V and a leakage current of 10 µA at VDRM. The component is housed in an SMTO-263-2 surface-mount package.

Triacs Feature Summary

• High thermal stability with a maximum operating temperature of +125 °C
• Surface-mount construction for automated PCB assembly
• Robust switching capability with 25 A RMS current handling

Triacs Applications

• AC motor speed control circuits
• Solid-state relay output stages
• Lighting dimmer modules

Triacs Procurement Notes

Verify the specific suffix 'H6RP' against the manufacturer's latest datasheet to confirm pinout orientation and tape-and-reel specifications. Ensure the procurement channel provides original Littelfuse documentation to validate RoHS compliance status and REACH SVHC declarations prior to integration into production designs.

Triacs Selection Notes

Select this component when a 400 V rating is required for low-voltage AC systems. Compare the 25 A RMS capacity against peak load requirements. Consider the SMTO-263-2 package dimensions for board space constraints. Verify that the gate trigger characteristics align with the driving circuit's output capabilities.

Triacs Part Context

This part belongs to the Qxx25xxHx series of high-temperature triacs from Littelfuse. It shares the 25 A current class with other variants but differs in voltage ratings and package types. The 'Q' prefix typically denotes standard thyristor performance, while the suffix indicates specific packaging and temperature grades.

Triacs Replacement Considerations

Direct substitutes must match the 400 V / 25 A specification and SMTO-263-2 footprint. Check equivalent parts from manufacturers like STMicroelectronics or ON Semiconductor for compatible pinouts and thermal resistance values.
