Overview
The Diodes Incorporated 1N5819M-13 is a surface mount Schottky barrier rectifier housed in a MELF glass package. It features a peak repetitive reverse voltage of 40 V and a maximum average forward rectified current of 1.0 A at 90°C. The device exhibits a low forward voltage drop of 0.600 V at 1.0 A and supports a maximum forward surge current of 25 A. Operating junction temperature ranges from -60 to +125 °C, with typical thermal resistance of 130 K/W.
Feature Summary
- Guard ring die construction for transient protection
- Glass MELF package for high reliability
- Low forward voltage drop for high efficiency
- High current capability
Applications
- Surface mount power supply circuits
- Free wheeling diode applications
- Polarity protection circuits
- Low voltage high frequency inverters
Procurement Notes
Verify the specific ordering suffix matches the required tape and reel quantity. Confirm the component meets RoHS compliance standards if restricted materials are prohibited. Check datasheet revision history for any updates to mechanical dimensions or electrical characteristics before finalizing procurement specifications.
Selection Notes
Select this component when surface mount technology is required for 1A Schottky rectification. The MELF glass package offers superior hermetic sealing compared to plastic alternatives. Ensure PCB layout accommodates the axial MELF footprint and allows for adequate thermal dissipation given the 130 K/W thermal resistance rating.
Part Context
This part belongs to the 1N5817M/18M/19M series of surface mount Schottky rectifiers. It shares identical physical dimensions and general features with the 1N5817M and 1N5818M variants, differing primarily in the peak repetitive reverse voltage rating. The series is designed to replace through-hole DO-41 packages in compact electronic designs.
Replacement Considerations
Direct pin-compatible replacements include other manufacturers' 1N5819M equivalents in MELF packages. Verify that substitute components maintain the same 40V reverse voltage rating and 1.0A current capacity. Ensure the replacement also utilizes a glass encapsulation if environmental reliability is a critical design constraint.
