Q6030LH3TP

Triacs Overview

The Littelfuse Q6030LH3TP is a high-temperature Alternistor triac designed for robust AC switching applications. It features a 600V rated repetitive off-state voltage and supports an RMS on-state current of 30A. The device utilizes a TO-220AB-3 insulated package, providing electrical isolation between the leads and the mounting surface. Key electrical parameters include a maximum holding current of 15mA, a gate trigger current of 10mA, and a typical on-state voltage of 1.6V. It operates within a junction temperature range of -40°C to +125°C and exhibits low leakage current characteristics.

Triacs Feature Summary

• Alternistor technology eliminates the need for external snubber networks in phase control circuits.
• Electrically isolated TO-220AB-3 package removes the requirement for separate insulators during installation.
• Glass-passivated junctions ensure long-term parameter stability and device reliability.

Triacs Applications

• AC motor speed controls
• Temperature modulation systems
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific suffix 'TP' against the manufacturer's official datasheet to confirm tape-and-reel packaging requirements. Ensure the selected component matches the exact voltage and current ratings required by the circuit design. Cross-reference the part number with Littelfuse documentation to validate RoHS compliance status and lead-free soldering compatibility before finalizing procurement orders.

Triacs Selection Notes

Select this component when high thermal endurance and noise immunity are critical for AC switching tasks. The Alternistor architecture simplifies circuit design by removing snubber components. Verify that the 30A RMS current capacity aligns with the load requirements. Confirm that the TO-220AB-3 package fits the available board space and thermal management constraints of the target application.

Triacs Part Context

This device belongs to the QxxxxLTx series of Quadrac and Alternistor devices developed by Littelfuse. These components integrate triac functionality with specialized triggering mechanisms to enhance performance in industrial and consumer AC control environments. The series is characterized by glass-passivated junctions and high-voltage capabilities up to 600V, targeting applications requiring reliable phase control without complex external protection networks.

Triacs Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalents. Generic triacs may lack the specific Alternistor snubber-less characteristics or the precise electrical isolation properties of the TO-220AB-3 package. Validate any substitute against the original datasheet specifications for voltage, current, and thermal performance.
