1N5826R

Overview

The GeneSiC Semiconductor 1N5826R is a silicon Schottky rectifier in the 1N58 series, rated for a continuous forward current of 15 A and a repetitive peak reverse voltage of 20 V. The 'R' suffix indicates reversed polarity where the stud functions as the anode. It operates within a junction temperature range of -55 °C to +150 °C and features a thermal resistance of 1.8 °C/W. Key electrical parameters include a maximum forward voltage of 470 mV at 15 A and a surge non-repetitive forward current capability of 500 A.

Feature Summary

• High surge current capability with robust thermal performance
• Not sensitive to electrostatic discharge (ESD)
• Hermetically sealed DO-4 package designed for stud mounting

Applications

• Secondary rectification in switching mode power supplies
• Free-wheeling diodes in high-frequency DC-to-DC converters
• Reverse polarity protection circuits
• Redundancy OR-ing applications

Procurement Notes

Verify that the specific part number includes the 'R' suffix to confirm reversed polarity configuration, as standard versions have the stud as the cathode while the 'R' variant has the stud as the anode. Confirm compliance with RoHS directives and ensure the supplier provides the official datasheet for the 1N5826R variant to validate terminal orientation before integration into the design.

Selection Notes

Select this component when a 15 A Schottky rectifier with low forward voltage drop is required in a stud-mount package. The 'R' designation is critical for designs requiring the stud to serve as the anode connection rather than the cathode. Ensure the application environment supports the specified operating temperature range up to 150 °C and that the mounting interface accommodates the DO-4 package dimensions.

Part Context

This device belongs to the 1N5826 through 1N5828R family of silicon power Schottky diodes manufactured by GeneSiC Semiconductor. These components are engineered for high-efficiency power conversion applications, offering superior switching characteristics compared to standard p-n junction rectifiers. The family covers voltage ratings from 20 V to 40 V, providing flexibility for various low-voltage, high-current power supply designs.

Replacement Considerations

Direct substitutes within the same family include the 1N5827R and 1N5828R, which share identical current ratings but offer higher reverse voltage capabilities of 30 V and 40 V respectively. When replacing the standard 1N5826, ensure the replacement also carries the 'R' suffix if the circuit layout relies on the stud being the anode terminal.
