QJ6040K3TP

Triacs Overview

The Littelfuse QJ6040K3TP is a standard TRIAC rated for 600 V peak repetitive off-state voltage and 40 A RMS on-state current. It features a gate trigger voltage of 1.3 V and a gate trigger current of 100 mA, with a maximum holding current of 100 mA. The device supports an on-state voltage of 1.3 V and non-repetitive surge currents up to 500 A. Operating within a temperature range of -40°C to +150°C, it utilizes an SMTO-218 package for through-hole mounting.

Triacs Feature Summary

• Provides electrical insulation up to 2.5 kV
• UL certified for UL 1557 standard compliance
• High junction temperature capability up to 150°C

Triacs Applications

• AC power switching circuits
• General AC control applications
• Industrial motor control systems

Triacs Procurement Notes

Verify the specific datasheet version for the QJ6040K3TP to confirm exact gate trigger parameters, as variations exist within the QJxx40xx series. Ensure the procurement source provides official Littelfuse documentation to validate the 2.5 kV insulation rating and UL certification status required for safety-critical designs.

Triacs Selection Notes

Select this component when high thermal stability and robust surge handling are required. The 150°C junction temperature rating exceeds standard TRIAC limits, making it suitable for demanding environments. Verify that the 600 V blocking voltage aligns with the system's peak line voltage requirements.

Triacs Part Context

This part belongs to the QJxx40xx series from Littelfuse, designed for low-power TRIAC applications up to 1200 V. The series emphasizes high reliability and safety certifications, targeting industrial and consumer AC power management solutions requiring durable thyristor components.

Triacs Replacement Considerations

Consider the QJ6040JH7TP or QJ6040M4TP as potential alternatives within the same manufacturer lineup. Verify pinout compatibility and thermal characteristics before substitution.
