Q8015R5

Triacs Overview

The Littelfuse Q8015R5 is a standard Triac from the Teccor Qxx15xx series, designed for AC switching and phase control applications. It features an RMS on-state current of 15 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220-2 through-hole package with an isolated tab. Key electrical parameters include a maximum holding current of 70 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 50 mA. Non-repetitive peak on-state currents are specified at 167 A and 200 A, with an on-state voltage of 1.6 V and a leakage current of 5 µA.

Triacs Feature Summary

• Integrated glass-passivated junctions ensure long-term parameter stability and device reliability.
• Electrically isolated mounting surface eliminates the need for external insulators in high-voltage isolation scenarios.
• Bidirectional AC switching capability supports gate control for either polarity of main terminal voltage.

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls

Triacs Procurement Notes

Verify the specific suffix R5 against the official Littelfuse datasheet to confirm pinout configuration and thermal characteristics. Ensure the procurement channel provides valid RoHS compliance documentation. Confirm that the TO-220-2 package variant matches the design requirements for isolated mounting surfaces. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 15 A continuous current capacity are required for AC load switching. The TO-220-2 package is suitable for applications requiring electrical isolation between the heatsink and circuit ground. Verify that the gate trigger current of 50 mA aligns with the driving circuit capabilities. Consider thermal management strategies given the 125°C maximum junction temperature rating.

Triacs Part Context

This component belongs to the Teccor Qxx15xx series of standard Triacs manufactured by Littelfuse. The series is characterized by glass-passivated junctions and robust construction for industrial AC control. The Q8015R5 specifically denotes the 800 V voltage rating within this family, distinguishing it from other variants such as the QK015R5 which offers higher voltage ratings.

Triacs Replacement Considerations

The part number alias Q8015R5TP may be used interchangeably depending on packaging specifications. Verify compatibility with existing PCB footprints and thermal interface materials when substituting.
