1N5819HW-7

Overview

The 1N5819HW-7 is a 1.0A surface-mount Schottky barrier rectifier from Diodes Incorporated, housed in an SOD123 package. It offers a peak repetitive reverse voltage of 40V and a maximum forward voltage drop of 450mV at 1.0A. The device features low reverse leakage current (50µA max) and high surge capability with a non-repetitive peak forward surge current of 25A. Operating temperatures range from -65°C to +150°C.

Feature Summary

• Guard ring die construction for transient protection
• Totally lead-free and fully RoHS compliant
• Halogen and antimony free green device

Applications

• Low-voltage, high-frequency inverters
• Free wheeling applications
• Polarity protection circuits

Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the tape and reel packing quantity of 3000 units as listed in the official datasheet. Confirm that the component meets all applicable environmental compliance standards including RoHS 2 and RoHS 3 directives before finalizing procurement specifications.

Selection Notes

Select this component for general rectification tasks requiring low forward voltage drop and high efficiency. Ensure the application operates within the specified 40V reverse voltage limit and 1.0A average output current. Consider thermal derating curves for ambient temperatures exceeding standard conditions to maintain reliability.

Part Context

This part belongs to Diodes Incorporated's line of surface-mount Schottky barrier rectifiers. It serves as a lead-free alternative to through-hole equivalents, offering similar electrical performance in a compact SOD123 package suitable for automated assembly processes in modern electronic manufacturing.

Replacement Considerations

An automotive-compliant version is available under the separate part number 1N5819HWQ. Verify if automotive qualification requirements necessitate this specific variant over the standard industrial grade 1N5819HW-7.
