QJ8006RH4TP

Triacs Overview

The Littelfuse QJ8006RH4TP is a bidirectional triac designed for high-power AC switching applications. It features an 800 V repetitive peak off-state voltage (VDRM) and supports a continuous on-state RMS current (IT(RMS)) of 6 A. The device utilizes a gate trigger voltage (VGT) of 1.3 V and a gate trigger current (IGT) of 35 mA to initiate conduction. It operates within a junction temperature range from -40 °C to +125 °C and is housed in a TO-220AB insulated flange mount package, facilitating efficient thermal management for industrial loads.

Triacs Feature Summary

• Insulated flange mount construction for direct heatsink attachment
• High dv/dt rating to prevent false triggering during rapid voltage transients
• Snubberless operation capability for simplified circuit design

Triacs Applications

• Industrial motor speed control systems
• Solid state relay modules
• AC power regulation circuits

Triacs Procurement Notes

Verify the specific suffix 'QJ' against official Littelfuse documentation to confirm exact pinout and insulation class variations. Ensure the ordering part number matches the required thermal interface specifications for your heatsink assembly. Cross-reference the datasheet revision date to validate parameter consistency before finalizing procurement orders.

Triacs Selection Notes

Select this component when an insulated TRIAC is required for high-voltage isolation between the control circuit and the heatsink. The 6 A RMS rating suits moderate power AC loads. Verify that the gate drive circuit can supply at least 35 mA to ensure reliable turn-on across the full operating temperature range without excessive delay.

Triacs Part Context

This part belongs to the Qxx06xxH series of high-reliability TRIACs from Littelfuse. The series is characterized by robust construction for demanding industrial environments. The 'QJ' prefix typically denotes specific packaging or insulation enhancements compared to standard variants within the same electrical family.

Triacs Replacement Considerations

Direct replacements include the Q8006RH4TP or Q8006LH4TP if insulation requirements differ. Verify that substitute parts maintain the same 800 V blocking voltage and 6 A current rating. Check package compatibility with existing mounting hardware before substitution.
