Q8008N5RP

Triacs Overview

The Littelfuse Q8008N5RP is a bidirectional triac designed for AC power control applications. It features an RMS on-state current (ItRMS) of 8 A and a rated repetitive peak off-state voltage (VDRM) of 800 V. The device operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum holding current (Ih) of 50 mA, a gate trigger voltage (Vgt) of 2.5 V, and a gate trigger current (Igt) ranging from 50 mA to 75 mA. The on-state voltage is specified at 1.6 V, with a maximum off-state leakage current of 10 µA at VDRM. It is housed in an SMTO-263-2 surface-mount package.

Triacs Feature Summary

• Bidirectional switching capability for alternating current circuits
• Surface-mount construction in an SMTO-263-2 package for automated assembly
• High thermal stability supporting operation up to +125°C

Triacs Applications

• AC motor speed control systems
• Solid-state relay implementations
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific suffix 'N5RP' against the manufacturer's official datasheet to confirm pinout configuration and triggering characteristics. Ensure the ordering quantity aligns with the standard reel packaging specifications provided by Littelfuse. Confirm RoHS compliance status through the latest environmental declaration documents before finalizing procurement orders.

Triacs Selection Notes

Select this component when an 8 A RMS current rating and 800 V blocking voltage are required for compact AC load switching. The SMTO-263-2 package is suitable for high-density PCB layouts. Verify that the gate drive circuit can supply the necessary 50 mA trigger current. Consider thermal management requirements given the 125°C maximum operating temperature limit.

Triacs Part Context

This part belongs to the Littelfuse Qxx series of triacs, which are engineered for general-purpose AC power control. The Q8008 variant specifically denotes the 8 A current rating within this family. These devices are commonly utilized in industrial and consumer electronics where reliable solid-state switching of AC loads is necessary.

Triacs Replacement Considerations

Consult Littelfuse documentation for direct replacements such as the Q8008NH3RP or Q8008NH4RP. Verify compatibility regarding gate sensitivity and package dimensions before substitution.
