Q4015R5TP

Triacs Overview

The Littelfuse Q4015R5TP is a Teccor brand Quadrac device, integrating a triac and a diac trigger within a single package. It serves as a bidirectional AC switch for phase control applications. The component features a 400V rated repetitive off-state voltage (VDRM) and supports an on-state RMS current (IT(RMS)) of 15A. Key electrical parameters include a gate trigger current (IGT) of 50mA, a holding current maximum of 70mA, and an on-state voltage of 1.6V. It operates within a temperature range of -40°C to +125°C and utilizes a TO-220-2 through-hole package.

Triacs Feature Summary

• Integrates a diac trigger inside the same package as the triac to eliminate external discrete components.
• Provides electrical isolation of 2500V rms from leads to mounting surface in the TO-220 package.
• Features glass-passivated junctions to ensure long-term device reliability and parameter stability.

Triacs Applications

• AC switching and phase control applications
• Speed controls requiring noise immunity
• Temperature modulation controls
• Lighting controls

Triacs Procurement Notes

Verify the specific suffix 'R5' against official Littelfuse documentation to confirm exact pinout and mechanical variations. Confirm RoHS compliance status via the manufacturer's datasheet or ECAD model metadata before integration. Ensure the TO-220-2 package dimensions match the target PCB footprint requirements.

Triacs Selection Notes

Select this component when a combined triac-diac solution is required for AC phase control. The integrated design reduces assembly time and cost compared to discrete arrangements. Verify that the 15A RMS current rating and 400V blocking voltage meet the circuit's load and supply requirements. Consider the thermal management needs associated with the TO-220-2 package for high-current operations.
