1N5819HWQ-7-F

Overview

The 1N5819HWQ-7-F is a single Schottky barrier rectifier manufactured by Diodes Incorporated in an SOD-123 surface-mount package. It features a peak repetitive reverse voltage of 40 V and an average rectified output current of 1.0 A. The device exhibits a maximum forward voltage of 750 mV at 1.0 A and a maximum reverse leakage current of 50 µA at 25°C. It supports a non-repetitive peak forward surge current of 25 A and operates within a temperature range of -65°C to +125°C. Qualified to AEC-Q101 standards, it offers high efficiency and transient protection via guard ring die construction.

Feature Summary

• Guard ring die construction provides enhanced transient protection capabilities.
• High surge capability ensures robustness against peak current events.
• Low forward voltage drop contributes to reduced power loss and high efficiency.
• Qualified to AEC-Q101 standards for automotive reliability requirements.

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration, as the standard reel quantity is 3000 units. Confirm that the component meets the necessary RoHS and halogen-free compliance standards for your assembly process. Ensure the procurement channel is authorized to guarantee product authenticity and traceability. Check for any specific PPAP documentation requirements if the application demands formal production part approval procedures.

Selection Notes

Select this component when a surface-mount Schottky rectifier with automotive qualification is required. The SOD-123 package suits space-constrained designs needing 1.0 A continuous current handling. Consider the low forward voltage characteristics for efficiency-critical low-voltage systems. Verify that the 40 V reverse voltage rating aligns with the circuit's peak inverse voltage requirements under all operating conditions.

Part Context

This part belongs to the 1N5819 series of Schottky rectifiers from Diodes Incorporated. The 'Q' suffix indicates automotive qualification to AEC-Q101 standards, while '-7-F' denotes the tape and reel packaging format. It serves as a surface-mount alternative to traditional through-hole rectifiers, offering similar electrical performance in a compact form factor suitable for modern automated assembly processes.

Replacement Considerations

Direct substitutes include other AEC-Q101 qualified 1.0A Schottky diodes in SOD-123 packages with matching 40V ratings. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement maintains equivalent forward voltage and reverse leakage specifications to preserve circuit efficiency and reliability.
