Triacs datasheet and documents for QK008DH4RP

QK008DH4RP

Triacs Overview

The Littelfuse QK008DH4RP is a bidirectional triac rated for 1000V repetitive peak off-state voltage and 8A RMS on-state current. It features a gate trigger voltage of 1.3V and a gate trigger current of 35mA, with a maximum holding current of 35mA. The device operates within a temperature range of -40°C to +125°C and exhibits an on-state voltage of 1.6V. Packaged in an SMTO-263-2 surface-mount format, it provides low leakage current of 20uA at rated voltage.

Triacs Feature Summary

High-voltage blocking capability suitable for demanding AC power control applications
Surface-mount construction designed for automated assembly processes
Robust thermal performance supporting operation up to 125°C junction temperature

Triacs Applications

Industrial motor speed control systems
Solid-state relay output stages
AC power switching circuits requiring high voltage isolation

Triacs Procurement Notes

Verify the specific suffix RP against official Littelfuse documentation to confirm package type and availability status. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity. Confirm RoHS compliance details directly from the datasheet before integration into regulated designs.

Triacs Selection Notes

Select this component when a 1000V rating is required for AC load switching. Ensure the PCB footprint matches the SMTO-263-2 outline dimensions provided in the mechanical drawings. Verify that the gate drive circuit can supply the specified 35mA trigger current reliably across the full operating temperature range.

Triacs Part Context

This device belongs to the Qxx08xHx series of high-voltage triacs manufactured by Littelfuse. The series offers standardized electrical characteristics for industrial power control, providing a reliable alternative to discrete thyristor solutions in compact surface-mount designs.
