1N5817

Overview

The SMC Diode Solutions 1N5817 is a silicon Schottky barrier rectifier designed for low voltage and high frequency applications. It features a maximum average forward rectified current of 1 A and a maximum repetitive peak reverse voltage of 20 V. The device utilizes a metal-semiconductor junction with guard ring protection to ensure transient stability. It is housed in a DO-41 axial leaded plastic package, suitable for through-hole mounting. Key electrical characteristics include a low forward voltage drop and high surge capability, making it efficient for power conversion circuits.

Feature Summary

• Schottky barrier construction provides extremely fast switching speeds and negligible switching losses.
• Guard ring protection design enhances reliability against transient voltage events.
• Low forward voltage drop minimizes conduction losses for improved system efficiency.
• High surge current capability supports robust performance under overload conditions.

Applications

• Free wheeling diodes in DC to DC converters
• Polarity protection circuits
• Low voltage high frequency inverters
• Small battery chargers

Procurement Notes

Verify the specific manufacturer datasheet for the SMC Diode Solutions variant, as parameters such as forward voltage and reverse leakage may differ from generic 1N5817 specifications. Confirm RoHS compliance status and packaging options directly with the supplier. Ensure the component meets the required thermal resistance and operating temperature range for the intended application environment before finalizing procurement.

Selection Notes

Select this component for applications requiring low forward voltage drop and fast recovery times at 20 V reverse voltage ratings. The DO-41 package is appropriate for through-hole assembly where axial leads are preferred. Consider the 1 A continuous current rating and ensure adequate heat dissipation for the specific circuit load. Verify that the avalanche capability and surge ratings align with the system's transient requirements.

Part Context

The 1N5817 belongs to the standard Schottky rectifier family, widely used in power supply designs. It serves as a common replacement for general-purpose low-voltage rectification tasks. The DO-41 package is a standard axial leaded form factor compatible with legacy and modern PCB layouts. This component type is distinct from higher voltage variants like the 1N5818 or 1N5819 within the same series.
