Q8015R5TP

Triacs Overview

The Q8015R5TP is a standard triac manufactured by Littelfuse under the Teccor brand, designed for AC switching and phase control applications. It features an 800V repetitive peak off-state voltage and a 15A RMS on-state current rating. The device utilizes a TO-220-2 package with an isolated tab for mounting. Key electrical parameters include a maximum gate trigger current of 50mA, a holding current of 70mA, and an on-state voltage of 1.6V. It operates within a junction temperature range of -40°C to 125°C and offers non-repetitive surge current capabilities of 167A at 50Hz and 200A at 60Hz.

Triacs Feature Summary

• Integrated bidirectional AC switching capability with gate control for either polarity of main terminal voltage.
• Electrically isolated mounting tab in the TO-220-2 package eliminates the need for external insulators.
• Glass-passivated junctions ensure long-term device reliability and parameter stability.

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls

Triacs Procurement Notes

Verify the specific suffix R5TP against official Littelfuse documentation to confirm pinout configuration and packaging details. Ensure the selected component matches the required isolation voltage and thermal management specifications for the target application environment before finalizing procurement orders.

Triacs Selection Notes

Select this component when an 800V blocking voltage and 15A continuous current capacity are required in a through-hole isolated package. Consider the 50mA gate trigger sensitivity and 1.6V on-state voltage drop for drive circuit design and thermal dissipation calculations relative to the TO-220-2 form factor.

Triacs Part Context

This part belongs to the Qxx15xx series of standard triacs from Littelfuse. The series provides robust AC power control solutions with glass-passivated junctions. The Q8015R5TP specifically denotes the 800V variant within this lineup, sharing common structural features like the isolated tab package found across similar current-rated devices in the family.

Triacs Replacement Considerations

Cross-reference with other Q8015 variants or equivalent 800V 15A triacs in TO-220 packages. Verify that any substitute maintains the same gate trigger characteristics and isolation requirements to ensure compatibility with existing PCB layouts and drive circuits.
