QJ6008NH4TP

Triacs Overview

The Littelfuse QJ6008NH4TP is a bidirectional triac from the Qxx08xHx series, rated for 600 V repetitive off-state voltage and 8 A RMS on-state current. It utilizes an Alternistor design optimized for high commutation performance in circuits with extremely inductive loads. The device operates within a junction temperature range of -40 °C to +150 °C and features a TO-220AB-3 through-hole 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.

Triacs Feature Summary

• Alternistor construction provides high dv/dt capability and superior commutation performance for highly inductive loads without requiring snubber circuits.

Triacs Applications

• AC solid-state switching for industrial and commercial equipment
• Phase control applications such as motor speed modulation and temperature controls
• Lighting controls and dimmer circuits

Triacs Procurement Notes

Verify the specific suffix 'NH4TP' against official Littelfuse documentation to confirm the exact tape-and-reel quantity and lead-free status. Ensure the ordering code matches the required TO-220AB-3 package variant. Cross-reference the manufacturer's latest datasheet for any updates to agency approvals or RoHS compliance declarations before finalizing procurement specifications.

Triacs Selection Notes

Select this component when high commutation performance is required for inductive loads like motors or transformers. The 600 V rating suits standard AC line applications. Verify that the 35 mA gate drive requirements align with the control circuitry capabilities. Consider the thermal management needs associated with the TO-220AB-3 package for the intended power dissipation levels.

Triacs Part Context

This part belongs to the Qxx08xHx series of 8 Amp sensitive, standard, and Alternistor triacs. The series offers voltage ratings up to 1000 V and surge capabilities up to 100 A. These devices are designed for AC switching and phase control, providing reliable solid-state switching without contact wear or arcing issues found in mechanical relays.

Triacs Replacement Considerations

Direct replacements within the same family include Q6008NH4RP, which shares identical electrical characteristics but uses an SMTO-263-2 surface-mount package instead of the through-hole TO-220AB-3 form factor. Verify pinout compatibility and thermal resistance differences when substituting between package types.
