Q6008LH5TP

Overview

The IXYS Q6008LH5TP is a snubberless Alternistor TRIAC rated for 600 V off-state voltage and 8 A RMS current. It utilizes an ITO-220AB (TO-220-3 Isolated Tab) through-hole package. The device features high static dv/dt capability, allowing direct gate triggering without external RC snubber networks in many applications. It supports phase control with short turn-off time and handles surge currents up to 100 A non-repetitively.

Feature Summary

• Snubberless design eliminates need for external RC networks
• High static dv/dt immunity for reliable triggering
• Short turn-off time for efficient phase control

Applications

• Lighting dimmers
• Motor speed controls
• Heater controllers

Procurement Notes

Verify the specific suffix LH5TP against the official datasheet to confirm snubberless characteristics and package isolation type. Ensure the procurement channel provides original manufacturer documentation to validate the 600V/8A ratings and TO-220AB form factor. Cross-reference the part number with authorized distributors to avoid counterfeit components affecting thermal performance.

Selection Notes

Select this component when snubberless operation is required to reduce bill of materials and board space. The 8 A rating suits moderate power AC loads. Verify that the application’s peak current does not exceed the 100 A non-repetitive surge limit. Consider the 600V blocking capability for standard line voltages. Ensure thermal management fits the TO-220AB package constraints.

Part Context

This part belongs to IXYS’ Alternistor family of TRIACs designed for simplified circuit designs. Unlike standard TRIACs, it integrates features to prevent false triggering from rapid voltage changes. It serves as a robust switching element for residential and industrial AC power control systems requiring high reliability and minimal external passive components.

Replacement Considerations

Direct substitutes include other snubberless TRIACs with matching 600V/8A ratings and TO-220 packages. Verify pinout compatibility and thermal resistance values. Check if alternative brands offer equivalent dv/dt ratings and gate trigger requirements to ensure seamless integration without circuit redesign.
