QJ6010LH4TP

Triacs Overview

The Littelfuse QJ6010LH4TP is a high-temperature Alternistor TRIAC designed for robust power control applications. It features a 600 V rated repetitive off-state voltage and supports an RMS on-state current of 10 A. The device operates within a junction temperature range from -40 °C to +150 °C, ensuring reliability in demanding thermal environments. Key electrical parameters include a maximum holding current of 15 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 10 mA. It exhibits a low on-state voltage of 1.6 V and minimal off-state leakage current of 10 uA at VDRM. Packaged in a TO-220AB-3 through-hole case, it offers efficient thermal management for industrial circuits.

Triacs Feature Summary

• High-temperature operation capability up to 150 °C junction temperature
• Alternistor technology providing enhanced ruggedness and noise immunity
• Low gate trigger current requirement for simplified drive circuitry
• Through-hole mounting for secure mechanical attachment

Triacs Applications

• Industrial motor speed control systems
• High-temperature heating element regulation
• Solid-state relay modules requiring thermal stability

Triacs Procurement Notes

Verify the specific suffix LH4TP against official Littelfuse documentation to confirm the exact package variant and temperature rating. Ensure compatibility with existing PCB footprints for the TO-220AB-3 configuration. Cross-reference datasheet revisions to validate electrical characteristics match design requirements before finalizing procurement orders.

Triacs Selection Notes

Select this component when applications demand reliable switching at elevated temperatures exceeding standard TRIAC limits. The low gate sensitivity facilitates direct coupling with microcontrollers or logic drivers without complex buffering. Consider the 10 A RMS rating against peak load currents to ensure adequate safety margins during transient conditions.

Triacs Part Context

This part belongs to the QJxx10xH series of high-temperature Alternistors from Littelfuse. Unlike standard TRIACs, Alternistors offer superior dv/dt immunity and reduced susceptibility to false triggering. This series is engineered specifically for harsh industrial environments where thermal stress and electrical noise are prevalent concerns.

Triacs Replacement Considerations

Direct pin-compatible substitutes within the same Littelfuse family include QJ6010LH3TP. Verify that alternative packages such as TO-220-2 or SMTO-218 meet thermal dissipation requirements if form factor changes are permissible.
