QJ8010N4RP

Triacs Overview

The Littelfuse QJ8010N4RP is a standard TRIAC from the QJxx10xx series, rated for 10 A RMS on-state current and 800 V blocking voltage. It utilizes a TO-263 (D²PAK) surface-mount package with non-isolated mounting tab. The device operates in Quadrants I, II, III, and IV, featuring a maximum gate trigger current of 50 mA in Quadrant IV and 25 mA in other quadrants. Key electrical parameters include a peak on-state voltage of 1.60 V, a holding current maximum of 35 mA, and an operating junction temperature range of -40°C to 150°C. It supports a non-repetitive surge current of 120 A at 60 Hz.

Triacs Feature Summary

• Standard TRIAC operation across all four triggering quadrants for versatile AC line control.
• Glass-passivated junctions ensure long-term parameter stability and reliability.
• Surface-mount D²PAK package design facilitates automated assembly and efficient thermal management.
• Restricted RFI generation capabilities minimize electromagnetic interference during switching events.

Triacs Applications

• AC solid-state switches and static switching relays
• Lighting controls and light dimmers
• Motor speed controls for power tools and appliances

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and lead form options. Ensure that the selected component meets the required RoHS compliance standards for the intended manufacturing process. Cross-reference the part marking system to validate authenticity upon receipt.

Triacs Selection Notes

Select this component for applications requiring high-temperature operation up to 150°C junction temperature. The 800 V rating provides adequate margin for standard AC line voltages. Consider the 120 A surge capability for handling inductive load turn-on currents. Verify that the PCB layout accommodates the TO-263 footprint and thermal requirements.

Triacs Part Context

This device belongs to the QJxx10xx series of 10 A high-temperature thyristors. The series includes both Alternistor and Standard TRIAC variants in TO-220 and TO-263 packages. The QJ8010N4RP specifically denotes the 800 V, 10 A, TO-263 standard TRIAC configuration within this product family.

Triacs Replacement Considerations

Direct substitutes within the same series include QJ8010R4RP (TO-220) or QJ8010L4RP (isolated TO-220). For different voltage ratings, consider QJ6010N4RP (600 V). Verify pinout compatibility and thermal resistance differences when substituting between package types.

Triacs FAQ

What is the critical rate-of-rise of off-state voltage (dv/dt) for this device?

For the 800 V variant, the minimum dv/dt is 600 V/µs at TVJ = 150°C with the gate open, and 800 V/µs at VD = 2/3 VDRM.

Does the QJ8010N4RP operate in all four quadrants?

Yes, as a standard TRIAC, it operates in Quadrants I, II, III, and IV, unlike Alternistor variants which are limited to three quadrants.

What is the maximum average gate power dissipation?

The average gate power dissipation is rated at 0.5 W at a junction temperature of 150°C.
