Overview
The B0520LW-7 is a 0.5A surface-mount Schottky barrier rectifier manufactured by Diodes Incorporated in an SOD123 package. It features a peak repetitive reverse voltage of 20V and an average rectified output current of 0.5A. The device has a maximum forward voltage drop of 0.385V at 0.5A and 25°C, with a non-repetitive peak forward surge current rating of 5.5A. Power dissipation is rated at 410mW, and the operating temperature range spans from -65°C to +125°C.
Feature Summary
- Low-forward voltage drop for improved efficiency
- Guard ring construction for transient protection
- High conductance characteristics
Applications
- General-purpose rectification in surface-mount circuits
- Power supply input rectification
- Free-wheeling diode applications in inductive loads
Procurement Notes
Verify the specific ordering suffix against official documentation, as variations such as -7-F or Q-7-F exist within the product family. Confirm that the procurement channel provides genuine components directly traceable to Diodes Incorporated manufacturing facilities. Ensure compliance with RoHS and halogen-free requirements if specified for the target application environment.
Selection Notes
Select this component when a low-voltage (20V) Schottky rectifier is required in a compact SOD123 footprint. Consider the thermal resistance and power dissipation limits relative to the expected ambient temperature and load conditions. Evaluate the forward voltage characteristics against system efficiency targets and ensure the surge current capability meets potential inrush requirements.
Part Context
This part belongs to the B0520 series of Schottky barrier rectifiers designed for general-purpose switching and rectification applications. The series offers various packaging options and voltage ratings to suit different circuit constraints. Diodes Incorporated produces these devices using silicon technology optimized for low forward voltage and high reliability in consumer and industrial electronics.
Replacement Considerations
Direct substitutes include B0520LW-7-F and B0520LWQ-7-F from Diodes Incorporated. Verify pinout compatibility and electrical parameter equivalence before substitution.
