1N5826

Overview

The GeneSiC Semiconductor 1N5826 is a silicon power Schottky rectifier designed for stud mounting applications. It features a DO-4 package with the standard configuration where the stud serves as the cathode and base. The device supports a repetitive peak reverse voltage of 20 V and a continuous forward current of 15 A. Key electrical parameters include a maximum non-repetitive surge forward current of 500 A, a forward voltage of 1.8 V at 15 A, and a reverse leakage current of 10 mA at 20 V. Operating temperatures range from -55 °C to 150 °C.

Feature Summary

• High surge capability for handling transient current loads
• Not sensitive to electrostatic discharge
• Standard polarity configuration with stud as cathode

Applications

• Power supply rectification
• Free-wheeling diodes in inductive circuits
• DC-DC converter output stages

Procurement Notes

Verify the specific ordering suffix when purchasing. Standard parts have the stud as the cathode, while variants ending in (R) feature reversed leads with the stud as the anode. Confirm the manufacturer designation, as production may be attributed to Navitas Semiconductor or GeneSiC Semiconductor depending on the batch and source documentation. Ensure compliance with RoHS requirements if specified by the supplier.

Selection Notes

Select this component for low-voltage, high-current applications requiring robust thermal performance and surge tolerance. The 20 V rating suits systems with low reverse voltage stress. Consider the DO-4 stud mount package for efficient heat dissipation to a chassis or heatsink. Verify that the 15 A continuous current rating meets the circuit's average load requirements and that the 500 A surge capacity covers potential inrush currents.

Part Context

The 1N5826 belongs to the 1N58 series of silicon power Schottky diodes manufactured by GeneSiC Semiconductor. This series includes variants with different voltage ratings, such as the 1N5827 and 1N5828, which share similar current and package characteristics but offer higher reverse voltage capabilities. The series is characterized by its stud-mount construction and high reliability for industrial power electronics.

Replacement Considerations

Compatible substitutes within the same series include the 1N5827 and 1N5828, provided their higher voltage ratings do not conflict with design constraints. For reverse polarity configurations, the 1N5826(R) variant is available. Cross-manufacturer equivalents must match the 15 A current, 20 V voltage, and DO-4 package dimensions.
