Q8008NH4TP

Triacs Overview

The Littelfuse Q8008NH4TP is a bidirectional 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 and features a maximum on-state voltage of 1.6 V. The device has a gate trigger voltage of 1.3 V and a gate trigger current of 35 mA, with a holding current maximum of 35 mA. It utilizes an SMTO-263-2 surface-mount package and offers non-repetitive peak on-state currents of 83 A and 100 A.

Triacs Feature Summary

• Bidirectional switching capability for AC power control applications
• Surface-mount construction in an SMTO-263-2 package for automated assembly
• High thermal stability supporting operation up to +125 °C

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm pinout and electrical tolerances. Confirm RoHS compliance status via official datasheets before integration. Ensure storage conditions maintain component integrity prior to soldering processes.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 8 A continuous current are required in a surface-mount form factor. Compare gate sensitivity requirements against the 35 mA trigger current specification. Evaluate thermal management needs based on the 1.6 V on-state voltage drop during conduction.

Triacs Part Context

This part belongs to the Qxx08xHx series of high-power triacs from Littelfuse. It shares core electrical characteristics with other variants in the family but differs in packaging and mounting style. The SMTO-263-2 package distinguishes it from through-hole alternatives like the TO-251-3 versions.

Triacs Replacement Considerations

Direct substitutes include Q8008NH4RP and Q8008NH3RP, which share identical electrical ratings and the SMTO-263-2 package. Verify that any replacement maintains the same gate trigger specifications and thermal performance limits.
