Overview
The B320AF-13-2477 is a surface-mount Schottky rectifier manufactured by Diodes Incorporated. It features a single diode configuration in an SMAF (DO-214AC) package. Key electrical parameters include a maximum repetitive reverse voltage of 60 V and an average rectified forward current of 3 A. The device exhibits a maximum forward voltage of 650 mV at the rated current and a reverse leakage current of 200 µA at 60 V. Operating temperature ranges from -55°C to +150°C junction temperature.
Feature Summary
- Utilizes silicon Schottky technology for fast recovery characteristics
- Designed for surface mount assembly in compact SMAF packages
- Capable of handling high surge currents with low thermal resistance
Applications
- DC-DC converter output rectification
- Free-wheeling diodes in power supply circuits
- Reverse polarity protection in electronic systems
Procurement Notes
Verify the specific suffix -2477 against the manufacturer's current active part list, as this designation may indicate obsolete or discontinued status. Confirm availability through authorized distributors only. Ensure the component matches the SMAF footprint and pinout requirements for the target PCB design before finalizing procurement orders.
Selection Notes
Select this component when a 60 V rating and 3 A continuous current capacity are required in a small surface-mount form factor. Consider the 650 mV forward voltage drop for efficiency calculations. Verify that the SMAF package dimensions fit within the available board space constraints compared to standard SMA or SMB packages.
Part Context
This part belongs to the B320AF series of Schottky rectifiers from Diodes Incorporated. It shares similar electrical characteristics with other variants in the series but differs in packaging and specific ordering suffixes. The SMAF package offers a smaller footprint than traditional axial or larger surface-mount diodes, suitable for dense circuit layouts.
Replacement Considerations
Diodes Incorporated recommends the B360AF-13 as a substitute. Verify compatibility regarding voltage ratings and package dimensions before replacement.
