QJ6008N5TP

Triacs Overview

The Littelfuse QJ6008N5TP is a high-temperature Bidirectional TRIAC (Alternistor) designed for robust power control applications. It features an RMS on-state current of 8 A and supports non-repetitive peak currents of 83 A or 100 A depending on the specific variant configuration. The device offers a rated repetitive off-state voltage (VDRM) of 600 V with a maximum leakage current of 10 uA under VDRM conditions. Key electrical parameters include an on-state voltage of 1.5 V, a holding current maximum of 35 mA, and gate trigger specifications of 1.3 V and 35 mA. It operates within a temperature range of -40 C to +150 C and utilizes a TO-220AB-3 through-hole package.

Triacs Feature Summary

• High-temperature capability suitable for demanding thermal environments
• Bidirectional switching functionality for AC power control
• Robust construction in a standard through-hole package

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay implementations
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the exact suffix designation against the manufacturer's official datasheet to confirm specific electrical tolerances and packaging details. Ensure compatibility with existing thermal management designs given the high operating temperature rating. Confirm pinout alignment with the TO-220AB-3 footprint during PCB layout finalization.

Triacs Selection Notes

Select this component when an 8 A RMS current rating and 600 V blocking voltage are required for AC load switching. Consider the TO-220AB-3 package for ease of heatsinking in high-power density designs. Evaluate the gate trigger requirements against the driving circuit capabilities to ensure reliable turn-on across the specified temperature range.

Triacs Part Context

This part belongs to the Littelfuse Qxx06xH series of Alternistors, which are specialized thyristors designed for high-temperature reliability. These devices are engineered to provide superior performance compared to standard TRIACs in harsh industrial and commercial environments where thermal stability is critical.

Triacs Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Generic TRIAC replacements may not match the specific high-temperature ratings or gate characteristics of the QJ6008N5TP.
