Q8015L5

Triacs Overview

The Littelfuse Q8015L5 is a standard Triac belonging to the Teccor Qxx15xx series, designed for AC switching and phase control applications. It features an 800 V rated repetitive off-state voltage (VDRM) and supports a continuous on-state RMS current of 15 A. The device utilizes a TO-220 package with an isolated tab for through-hole mounting. 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. It operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• Integrated isolation in the TO-220 package eliminates the need for external insulators.
• Glass-passivated junctions ensure long-term parameter stability and reliability.
• Bidirectional gate control allows operation with either polarity of main terminal voltage.

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact electrical tolerances and packaging options. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure the selected variant matches the required thermal management and isolation specifications for the target circuit design.

Triacs Selection Notes

Select this component for applications requiring robust AC phase control with high voltage blocking capabilities. The 15 A current rating suits moderate power loads. Verify that the gate drive circuit can supply the specified 50 mA trigger current. Consider the thermal resistance of the TO-220 package when designing heat dissipation strategies for continuous operation at full load.

Triacs Part Context

This part belongs to the Teccor Qxx15xx series of Triacs manufactured by Littelfuse. The series offers various voltage and current ratings packaged in TO-220 formats. These devices are engineered for general-purpose AC switching where noise immunity and reliable triggering are critical requirements.

Triacs Replacement Considerations

Q8015R5 is a documented alternate part number within the same family offering identical core electrical characteristics. Verify pinout compatibility and thermal performance before substitution.
