Q8008N5TP

Triacs Overview

The Littelfuse Q8008N5TP is a TE5 series bidirectional triac rated for 800V repetitive peak off-state voltage and 8A RMS on-state current. It utilizes a TO-263 (D²Pak) surface-mount package with two leads. Key electrical parameters include a maximum gate trigger voltage of 2.5V and a gate trigger current of 50mA. The device maintains an on-state voltage of 1.6V and a holding current maximum of 50mA. It supports non-repetitive peak on-state currents of 83A and 100A, with a leakage current of 50µA at rated voltage. Operating temperatures range from -40°C to +125°C.

Triacs Feature Summary

• Designed for high-voltage AC switching applications requiring robust thermal performance in compact surface-mount form factors.

Triacs Applications

• Solid-state relays
• Motor speed control circuits
• Lighting dimmer controls

Triacs Procurement Notes

Verify the specific suffix 'TP' against official Littelfuse documentation to confirm the tube packaging configuration and lead finish specifications. Ensure the ordering quantity aligns with manufacturer standard packing units to avoid partial reel or tube discrepancies during fulfillment.

Triacs Selection Notes

Select this component when a through-hole equivalent like the Q8008L5TP must be replaced by a surface-mount solution. Confirm that the PCB layout accommodates the TO-263 thermal pad requirements and that the 8A RMS current rating meets the load demands without exceeding thermal limits.

Triacs Part Context

This part belongs to the Littelfuse TE5 Triac family, which focuses on high-reliability power control solutions. The Q8008 variant specifically addresses applications needing 800V blocking capability with moderate current handling in a space-constrained environment.

Triacs Replacement Considerations

The Q8008L5TP serves as a pin-compatible through-hole alternative within the same product family. Verify thermal resistance differences between the TO-220 and TO-263 packages when substituting.
