Overview
The B245AF-13 is a 2.0A Schottky barrier rectifier from Diodes Incorporated, housed in an SMAF surface-mount package. It features a maximum repetitive reverse voltage of 45V and a typical forward voltage drop of 0.46V at 2A and +25°C. The device supports an average rectified output current of 2A and withstands a non-repetitive peak forward surge current of 50A. Operating junction temperature ranges from -55°C to +150°C with a thermal resistance (junction-to-ambient) of 90°C/W.
Feature Summary
- Guard ring die construction for transient protection
- Reduced low forward voltage drop for better efficiency and cooler operation
- Reduced high-temperature reverse leakage to increase reliability against thermal runaway failure
Applications
- Boost diode circuits
- Blocking diode applications
- Recirculating diode implementations
Procurement Notes
Verify the specific ordering suffix matches the required packaging configuration. Confirm that the component meets RoHS compliance standards and halogen-free requirements as defined by the manufacturer's green product specifications. Ensure the SMAF package dimensions align with the intended PCB footprint layout before finalizing procurement orders.
Selection Notes
Select this component for general rectification tasks requiring low forward voltage and high-temperature stability. The SMAF case provides a compact solution suitable for automatic assembly processes. Consider the 45V reverse voltage rating and 2A current capacity when designing circuits that demand efficient power conversion with minimal heat generation.
Part Context
This part belongs to the B220AF-B245AF series of 2.0A Schottky barrier rectifiers. The series offers varying reverse voltage ratings from 20V to 45V while maintaining consistent current handling capabilities. All variants share identical mechanical characteristics and package styles, differing primarily in their blocking voltage specifications.
Replacement Considerations
Compatible substitutes within the same series include B220AF-13, B230AF-13, and B240AF-13. These parts share the same SMAF package and 2.0A current rating but offer different reverse voltage thresholds ranging from 20V to 40V.
