Description and Introduction

45V 80A Schottky Common Cathode Diode in a D61-8-SL package **Introduction to the 81CNQ045ASL Schottky Diode from International Rectifier**  

The **81CNQ045ASL** is a high-performance Schottky diode designed by International Rectifier (IR) for demanding power applications. Featuring a dual common-cathode configuration, this component is optimized for efficiency in rectification circuits, particularly where low forward voltage drop and fast switching are critical.  

With a **45V reverse voltage rating** and a **current handling capacity of 40A per diode**, the 81CNQ045ASL is well-suited for use in switch-mode power supplies (SMPS), DC-DC converters, and motor control systems. Its Schottky barrier technology ensures minimal conduction losses, enhancing thermal performance and energy efficiency.  

Key characteristics include a **low forward voltage (typically 0.55V at 20A)** and **ultra-fast recovery time**, reducing switching losses in high-frequency applications. The device is housed in a TO-247 package, providing robust thermal dissipation and mechanical durability.  

Engineers favor the 81CNQ045ASL for its reliability in high-current environments, making it a preferred choice for industrial, automotive, and renewable energy applications. Its design balances performance with thermal stability, ensuring consistent operation under demanding conditions.  

For designers seeking an efficient, high-current rectification solution, the 81CNQ045ASL offers a dependable option with proven performance in power electronics.
