Overview
The B0520WS-7-F is a Schottky barrier rectifier manufactured by Diodes Incorporated, housed in the SOD-323 surface-mount package. It features a peak repetitive reverse voltage (Vrrm) of 20 V and a maximum average forward rectified current (Io) of 500 mA. The device exhibits a low forward voltage drop (Vf) of 430 mV at 500 mA and a maximum reverse leakage current (Ir) of 250 µA. It supports a non-repetitive peak forward surge current (Ifsm) of 2 A and operates within a junction temperature range of -55°C to +125°C.
Feature Summary
- Utilizes Schottky barrier technology for high switching efficiency and minimal power loss.
- Features a compact SOD-323 surface-mount package designed for automated assembly and space-constrained layouts.
- Provides low forward voltage characteristics to enhance overall system efficiency.
Applications
- DC-DC converter output rectification
- Free-wheeling diode applications in inductive load circuits
- Power supply input protection against reverse polarity
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the component meets all relevant environmental compliance standards required for the target application before finalizing procurement decisions.
Selection Notes
Select this component when a low-voltage, high-efficiency rectification solution is required in a small form factor. Consider the 20 V rating and 500 mA current capacity relative to the circuit's peak operating conditions to ensure adequate safety margins during design implementation.
Part Context
This part belongs to the B0520WS series of Schottky rectifiers from Diodes Incorporated. The series is engineered for general-purpose rectification in portable and battery-powered devices where low forward voltage and fast switching speeds are critical for maintaining performance and extending battery life.
Replacement Considerations
Consult official substitution guides for verified equivalents. Cross-reference key parameters such as Vrrm, If, Vf, and package dimensions to ensure functional compatibility without modifying the existing PCB layout or thermal management design.
