Triacs datasheet and documents for QK008NH4TP

QK008NH4TP

Triacs Overview

The Littelfuse QK008NH4TP 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 1 kV. The device operates within a temperature range of -40 °C to +125 °C. 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. The non-repetitive on-state peak currents are specified as 83 A and 100 A. The component utilizes an SMTO-263-2 package and is supplied in a reel format.

Triacs Feature Summary

High-voltage blocking capability suitable for demanding AC power control environments
Surface-mount construction optimized for automated PCB assembly processes
Robust thermal performance supporting operation up to 125 °C

Triacs Applications

Industrial motor speed control systems
Solid-state relay switching modules
AC power regulation circuits

Triacs Procurement Notes

Verify the specific suffix 'TP' against official Littelfuse documentation to confirm tube packaging requirements. Ensure the ordered quantity aligns with manufacturer minimum order increments. Cross-reference the full part number to distinguish from similar variants like the RP reel version. Confirm RoHS compliance status through the latest datasheet before finalizing procurement specifications.

Triacs Selection Notes

Select this component when a 1 kV rating is required for high-voltage AC switching. The 8 A RMS current capacity suits moderate power loads. Verify that the SMTO-263-2 footprint fits the target PCB layout. Consider the 35 mA gate drive requirement for compatible control circuitry design. Evaluate thermal management needs given the 125 °C maximum junction temperature limit.

Triacs Part Context

This triac belongs to the Qxx08xHx series from Littelfuse, which groups devices by their 8 A current handling and 1 kV voltage ratings. The family includes variations such as QK008NH4RP, differing primarily in packaging type. This specific model represents the tube-packaged variant within the broader high-power thyristor portfolio.
