Overview
The 1N5819HW-13 is a surface mount Schottky barrier rectifier manufactured by Diodes Incorporated in the SOD-123 plastic package. It provides an average rectified output current of 1.0 A at a terminal temperature of 90°C and supports a peak repetitive reverse voltage of 40 V. The device features a low forward voltage drop, with maximum values of 0.750 V at 1.0 A and 0.450 V at 0.1 A. It operates within a junction and storage temperature range of -65 to +125°C and dissipates up to 450 mW of power.
Feature Summary
- Guard ring die construction designed for transient protection
- Low power loss and high efficiency characteristics
- High surge capability with 25 A non-repetitive peak forward surge current
Applications
- Low voltage, high frequency inverters
- Free wheeling applications
- Polarity protection circuits
Procurement Notes
Verify that the specific ordering suffix matches the required packaging configuration, as standard datasheets may list different shipping quantities such as tape and reel formats. Confirm the component meets RoHS compliance requirements and ensure the manufacturer's quality standards align with your supply chain specifications before finalizing procurement orders.
Selection Notes
Select this component for general rectification tasks requiring low forward voltage and high efficiency. Ensure the operating environment stays within the specified thermal limits and consider derating the current by 20% if used with capacitive loads. Verify that the SOD-123 package dimensions fit the available PCB space and that the 40 V reverse voltage rating exceeds the circuit's peak working voltage.
Part Context
This part belongs to the 1N5819 series of surface mount Schottky barrier rectifiers from Diodes Incorporated. While the base 1N5819 designation often refers to axial lead packages, the HW variant specifically denotes the SOD-123 surface mount form factor. This series is engineered for applications demanding fast switching speeds and minimal conduction losses in compact electronic designs.
Replacement Considerations
Consult the official datasheet for compatible alternatives within the same product family. Verify that any substitute maintains identical electrical ratings, including the 40 V reverse voltage and 1.0 A current capacity, while ensuring the replacement package matches the SOD-123 footprint for direct board integration.
