83CNQ080SL

Overview

The 83CNQ080SL is a dual common cathode Schottky rectifier manufactured by SMC Diode Solutions. This component utilizes Super Barrier Rectifier (SBR) technology to deliver high efficiency and low forward voltage drop. It features an 80-volt repetitive peak reverse voltage rating and an average forward current of 3 amperes per diode. The device is housed in a TO-263AB (D2PAK) surface-mount package, designed for robust thermal performance and reliable operation in demanding power conversion applications.

Feature Summary

• Super Barrier Rectifier technology ensures superior switching characteristics compared to traditional silicon junctions.
• Low forward voltage drop minimizes conduction losses and improves overall system efficiency.
• High surge current capability provides resilience against transient overload conditions.
• Lead-free finish and halogen-free construction comply with international environmental standards.

Applications

• DC-DC converters
• Power factor correction circuits
• Freewheeling diodes in synchronous rectification designs

Procurement Notes

Verify the specific ordering suffix to confirm exact packaging configuration, such as tape-and-reel quantities or lead plating variations. Confirm that the requested part matches the TO-263AB footprint dimensions required for your PCB layout. Ensure compliance with RoHS directives if operating in regulated markets. Cross-reference the manufacturer's latest datasheet for any updates on material composition or recommended soldering profiles prior to final procurement decisions.

Selection Notes

Select this component when low forward voltage drop is critical for efficiency in medium-current applications. The TO-263AB package offers a balance between thermal dissipation capabilities and surface-mount convenience. Consider the 80V rating to ensure adequate margin above the maximum reverse voltage expected in the circuit. Evaluate the thermal resistance parameters to determine if additional heatsinking is necessary for continuous high-load operations.

Part Context

This device belongs to the CNQ series of Super Barrier Rectifiers from SMC Diode Solutions. The series is engineered to replace standard fast recovery diodes in various power supply topologies. The dual common cathode configuration allows for use in half-bridge or full-bridge rectifier circuits within a single compact package, reducing board space requirements.

Replacement Considerations

Consult official substitution guides for equivalent parts with matching voltage and current ratings. Verify pinout compatibility before replacing existing components. Ensure thermal management requirements are met by any alternative device selected.
