Overview
The 1N5819HW-7-F is a Schottky rectifier diode manufactured by Diodes Incorporated, housed in the SOD-123 surface-mount package. It features a maximum repetitive peak reverse voltage (Vrrm) of 40 V and a maximum average forward rectified current (If) of 1 A. The device exhibits a low forward voltage drop (Vf) of up to 750 mV at 1 A and a low leakage current (Ir) of 3 mA at 40 V. It operates within a junction temperature range of -65°C to +125°C and supports a non-repetitive peak forward surge current (Ifsm) of 25 A.
Feature Summary
- Low forward voltage drop for improved efficiency
- High temperature stability across wide operating ranges
- Molded plastic case with excellent mechanical strength
Applications
- Low voltage high frequency inverters
- Free wheeling diodes
- Power supply rectification
Procurement Notes
Verify the specific suffix against official Diodes Incorporated documentation to confirm exact ordering specifications. Ensure compatibility with SOD-123 footprint requirements during PCB design. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before final procurement decisions.
Selection Notes
Select this component for applications requiring efficient rectification in low voltage circuits. The SOD-123 package offers space-saving advantages for surface mount designs. Consider the 40 V rating and 1 A current capacity when designing power stages. Evaluate thermal management needs based on the specified forward voltage and ambient operating conditions.
Part Context
This part belongs to the 1N5819HW series of Schottky rectifiers from Diodes Incorporated. It serves as a surface-mount alternative to traditional through-hole rectifiers, providing similar electrical characteristics in a compact form factor. The series is designed for general-purpose rectification tasks where low loss and fast switching are beneficial.
Replacement Considerations
Direct substitutes include other 1A 40V Schottky diodes in SOD-123 packages such as those from Vishay or ON Semiconductor. Verify pinout compatibility and ensure equivalent Vf and Ir specifications. Check for any differences in thermal resistance or packaging dimensions that might affect assembly.
