Q8008NH4RP

Triacs Overview

The Littelfuse Q8008NH4RP 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. Non-repetitive peak on-state currents are specified at 83 A and 100 A, with an on-state voltage of 1.6 V and a leakage current of 10 uA.

Triacs Feature Summary

• Surface-mount construction in an SMTO-263-2 package for automated assembly
• Bidirectional switching capability with high thermal stability up to 125°C
• Low gate sensitivity requiring minimal drive current for reliable triggering

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and packaging configuration. Ensure compatibility with standard SMD reflow profiles. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement specifications.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 8 A continuous current rating are required in a compact surface-mount form factor. Compare gate trigger characteristics against driver capabilities to ensure sufficient margin. Evaluate thermal management requirements based on the SMTO-263-2 package constraints for the intended operating environment.

Triacs Part Context

This part belongs to the Qxx08xHx series of triacs from Littelfuse. It shares core electrical ratings with other variants in the family but differs in physical packaging and specific manufacturing revisions. The NH4RP designation indicates the specific lead-free tape-and-reel packaging configuration.

Triacs Replacement Considerations

Direct substitutes include Q8008NH3RP and Q8008LH4, which share identical 800 V/8 A ratings. Verify package compatibility, as LH4 uses through-hole mounting while NH3RP may differ in reel specifications.
