QJ8008N5TP

Triacs Overview

The Littelfuse QJ8008N5TP is a bidirectional triac from the Teccor Qxx15xx series, designed for AC power control applications. It features an RMS on-state current of 8 A and supports a rated repetitive off-state voltage (VDRM) of 800 V. The device operates within a junction temperature range of -40 °C to +125 °C and utilizes an SMTO-263-2 surface-mount package. Key electrical characteristics include a maximum holding current of 70 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 50 mA. Non-repetitive peak on-state currents are specified at 167 A and 200 A under different conditions, with an on-state voltage of 1.6 V and a leakage current of 5 µA at VDRM.

Triacs Feature Summary

• Bidirectional switching capability for AC load control
• Surface-mount SMTO-263-2 packaging for automated assembly
• High thermal stability operating up to +125 °C

Triacs Applications

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

Triacs Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Littelfuse or authorized distributors before integration. Confirm that the SMTO-263-2 footprint matches the target PCB layout requirements. Ensure thermal management strategies account for the 125 °C maximum junction temperature limit during high-current operation cycles.

Triacs Selection Notes

Select this component when an 8 A RMS current rating and 800 V blocking voltage are required in a compact surface-mount form factor. Compare against the Q8015N5TP if higher current capacity is needed. Verify that the 50 mA gate trigger current aligns with the driving circuit's output capabilities to ensure reliable turn-on across the full operating temperature range.

Triacs Part Context

This part belongs to the Littelfuse Teccor Qxx15xx series of triacs, which are engineered for general-purpose AC power switching. The series offers various current ratings in standardized packages to facilitate design flexibility. The QJ8008N5TP specifically addresses mid-range power applications requiring robust performance in consumer and industrial electronics.

Triacs Replacement Considerations

The Q8015N5TP is a verified substitute within the same family offering higher current capacity. Check pinout compatibility and thermal resistance differences when substituting. No other direct cross-model replacements are confirmed in public documentation.
