Triacs datasheet and documents for Q8008DH4TP

Q8008DH4TP

Triacs Overview

The Littelfuse Q8008DH4TP is an Alternistor TRIAC rated for 800 V repetitive off-state voltage and 8 A RMS on-state current. It operates within a junction temperature range of -40 °C to +125 °C. Key electrical parameters include a maximum gate trigger voltage of 1.3 V, a maximum gate trigger current of 35 mA, and a holding current of 35 mA. The device features a minimum critical rate of rise of off-state voltage (dv/dt) of 250 V/µs and a minimum critical rate of rise of commutating dv/dt of 25 V/µs. It is housed in a TO-252AA surface-mount package with three terminals.

Triacs Feature Summary

High reliability construction designed for robust industrial environments
Integrated thermal protection mechanisms to prevent overheating during operation
Sensitive gate triggering capability requiring low control power

Triacs Applications

Solid state relays
Industrial motor controls
Lighting dimmers

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and packaging configuration. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 8 A continuous current are required in a compact SMD form factor. Consider the TO-252AA package for automated assembly processes. Evaluate the thermal management needs based on the 125 °C maximum operating temperature limit.

Triacs Part Context

This part belongs to the Qxx08xHx series of Alternistors from Littelfuse. These devices combine TRIAC functionality with integrated thermal shutdown protection. The series is engineered for high-reliability applications where standard TRIACs might fail due to thermal stress.
