Triacs datasheet and documents for Q4025N5TP

Q4025N5TP

Triacs Overview

The Littelfuse Q4025N5TP is a bidirectional triac in the Qxx25xx series, rated for 400V repetitive peak off-state voltage and 25A RMS on-state current. It features a maximum gate trigger voltage of 2.5V and a gate trigger current of 50mA. The device has an on-state voltage of 1.8V and a holding current maximum of 100mA. Non-repetitive surge currents are rated at 167A and 200A. It operates within a temperature range of -40°C to +125°C and is housed in an SMTO-263-2 surface-mount package.

Triacs Feature Summary

Glass-passivated junctions for enhanced reliability and protection against environmental factors
Solid-state switching capability eliminates arcing and contact bounce associated with mechanical relays

Triacs Applications

AC solid-state switching applications
Lighting control systems including dimmers
Motor speed modulation controls
Temperature modulation controls
Static switching relays

Triacs Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status through current documentation as regulatory requirements may evolve. Ensure storage conditions maintain device integrity prior to assembly. Validate package type matches the SMTO-263-2 specification for proper PCB footprint alignment during procurement planning.

Triacs Selection Notes

Select this component when a 400V rating and 25A continuous current capacity are required for AC phase control. The sensitive gate characteristic simplifies driver circuit design compared to standard or high-current gate variants. Consider the SMTO-263-2 package for surface-mount assembly needs. Evaluate thermal management requirements based on the 1.8V on-state voltage drop under load conditions.

Triacs Part Context

This part belongs to the Littelfuse Qxx25xx series of bidirectional triacs. These devices are designed for general-purpose AC power control applications. The series offers various voltage ratings and gate sensitivities to suit different circuit requirements while maintaining consistent physical dimensions for board layout flexibility across similar power levels.
