86CNQ200SMS2

Overview

The 86CNQ200SMS2 is a Schottky diode array manufactured by SMC Diode Solutions, designed for high-efficiency rectification in power electronics. It features a single pair common cathode configuration housed in the PRM2-SM through-hole package. The device supports a maximum DC reverse voltage of 200 V and an average rectified current of 80 A per diode. Key electrical characteristics include a forward voltage of 1.35 V at 80 A and a reverse leakage current of 40 mA at 200 V. It operates within a junction temperature range of -55°C to 175°C.

Feature Summary

• Schottky barrier technology ensures fast recovery times and low forward voltage drop for improved energy efficiency.
• Common cathode dual configuration simplifies circuit design for center-tap or full-wave rectifier applications.
• PRM2-SM through-hole mounting provides robust mechanical stability and ease of integration into chassis-based systems.

Applications

• DC power supply rectification
• Free-wheeling diodes in switching regulators
• Inverter output rectification
• Battery charging circuits

Procurement Notes

Verify the complete part number including the SMS2 suffix to ensure correct package type and pinout compatibility. Confirm RoHS3 compliance requirements with the supplier. Check datasheet thermal resistance values for proper heatsink selection. Ensure mounting torque specifications are followed to maintain reliable electrical contact and prevent mechanical stress on the semiconductor die during operation.

Selection Notes

Select this component when a 200 V blocking voltage and 80 A continuous current capacity are required in a through-hole format. The Schottky technology is suitable for frequencies where fast recovery is critical to minimize switching losses. Compare thermal performance against alternative packages if space constraints exist. Ensure the application current does not exceed the rated average rectified current under all operating conditions.

Part Context

This module belongs to the CNQ series of Schottky rectifiers from SMC Diode Solutions. The series offers various voltage and current ratings in standardized packages like PRM2 and PRM4. The 86CNQ200SMS2 specifically utilizes the PRM2-SM variant, distinguishing it from chassis-mount equivalents by its through-hole lead configuration for PCB assembly.

Replacement Considerations

Direct substitutes include other 200V 80A Schottky arrays in PRM2-SM packages from compatible manufacturers. Verify pin compatibility and thermal characteristics before substitution. Generic replacements must match the common cathode configuration and through-hole mounting style.
