LQA20T300C

Diode Arrays Overview

The LQA20T300C is a Q-Series common-cathode fast recovery diode manufactured by Power Integrations. It features a 300 V reverse voltage rating and a 20 A average forward current capability. The component utilizes qspeed technology, characterized by low reverse recovery charge (Qrr) and low reverse leakage current (Irrm). This design enables high di/dt switching rates up to 1000 A/µs with soft recovery characteristics. Packaged in TO-220AB for through-hole mounting, it operates within a temperature range of -55°C to +175°C.

Diode Arrays Procurement Notes

Verify the specific suffix 'C' against the official datasheet to confirm package type and pinout configuration. Ensure the selected distributor provides genuine Power Integrations products with traceable lot codes. Cross-reference the ordering part number with the manufacturer's latest release notes to confirm availability status and any potential obsolescence notices before finalizing procurement plans.

Diode Arrays Selection Notes

Select this component for applications requiring high-speed switching with minimal electromagnetic interference. The common-cathode configuration simplifies circuit layout for half-bridge or full-bridge topologies. Consider the thermal management requirements associated with the TO-220AB package when designing for continuous high-current operation. Verify that the 300V rating provides sufficient margin for the specific DC bus voltage of the target application.
