Q8008NH3RP

Triacs Overview

The Littelfuse Q8008NH3RP is a bidirectional triac designed for surface-mount applications. It features an RMS on-state current of 8 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device operates within a temperature range of -40°C to +125°C and utilizes an SMTO-263-2 package. Key electrical parameters include a maximum holding current of 35 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. It exhibits a low on-state voltage of 1.6 V and a leakage current of 10 uA at VDRM.

Triacs Feature Summary

• Surface-mount construction in an SMTO-263-2 package for automated assembly
• High voltage blocking capability suitable for AC power control circuits
• Low gate sensitivity facilitating direct drive from logic interfaces

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix '3' against the manufacturer datasheet to confirm exact gate characteristics and thermal ratings. Ensure the ordering code matches the required tape-and-reel packaging format. Confirm RoHS compliance status with the supplier prior to finalizing procurement orders.

Triacs Selection Notes

Select this component when an 800 V rating is required for high-voltage AC loads. The SMTO-263-2 package is appropriate for PCBs requiring surface-mount technology. Verify that the 35 mA gate trigger current aligns with the driving circuit's output capabilities.

Triacs Part Context

This part belongs to the Qxx08xHx series of high-voltage triacs from Littelfuse. These devices are engineered for robust performance in industrial and consumer AC power applications. The series offers various packages to accommodate different thermal and spatial constraints.

Triacs Replacement Considerations

Cross-reference with Q8008NH4RP for similar specifications but verify if the suffix change alters gate parameters or thermal resistance. Check Q8008DH4RP for alternative TO-252-3 packaging options.
