LQA30A300C

Diode Arrays Overview

The LQA30A300C is a Q-Series common-cathode rectifier manufactured by Power Integrations. It features a 300 V reverse voltage rating and a continuous forward current of 30 A. The device utilizes fast recovery technology with an ultra-low reverse recovery charge (Qrr). It is housed in a TO-247AD package, suitable for surface mount or through-hole installation depending on the specific variant suffix, and supports high junction temperatures up to +150°C.

Diode Arrays Feature Summary

• Ultra-low reverse recovery charge (Qrr) for reduced switching losses
• Common-cathode configuration for bridge applications
• High thermal stability with maximum junction temperature of +150°C

Diode Arrays Applications

• Power factor correction (PFC) circuits
• High-frequency DC/DC converters
• Uninterruptible power supplies (UPS)
• Industrial power supplies

Diode Arrays Procurement Notes

Verify the exact package type and pinout compatibility before procurement, as variations may exist within the Q-Series line. Confirm RoHS compliance status via the official datasheet. Ensure the selected variant matches the required thermal management solution for the intended 30 A load application.

Diode Arrays Selection Notes

Select this component for designs requiring high efficiency at elevated frequencies where low reverse recovery charge is critical. Compare the thermal resistance characteristics against the system's heat dissipation capabilities. Ensure the 300 V rating provides sufficient margin for the peak inverse voltage in the target circuit topology.

Diode Arrays Part Context

This part belongs to Power Integrations' Q-Series, which focuses on high-performance silicon rectifiers designed to replace faster but more expensive wide-bandgap devices in certain cost-sensitive applications. The series emphasizes low Qrr to improve overall converter efficiency without the complexity of GaN or SiC drivers.

Diode Arrays Replacement Considerations

Direct replacements include other Q-Series common-cathode diodes with similar ratings, such as the LQA32T300C or LQA60A300C, provided the package and current handling meet the design requirements. Verify that substitute parts maintain the same reverse recovery characteristics.
