Overview
The B350AF-13 is a 3.0A Schottky barrier rectifier manufactured by Diodes Incorporated, housed in an SMAF surface-mount package. It features a peak repetitive reverse voltage (VRRM) of 50V and supports an average rectified output current (IO) of 3A. The maximum forward voltage drop (VF) is rated at 0.65V at +25°C with a 3A forward current. Reverse leakage current (IR) is limited to 0.2mA at 50V and +25°C. The device operates within a temperature range of -55°C to +150°C and includes a non-repetitive peak forward surge current rating of 80A.
Feature Summary
- Reduced low forward voltage drop for improved efficiency and cooler operation
- Stable high-temperature reverse leakage characteristics to prevent thermal runaway
- Guard ring die construction designed for transient protection
Applications
- Boost diode circuits
- Blocking diode applications
- Recirculating diode configurations
Procurement Notes
Verify the specific ordering suffix matches the required packaging format before procurement. Confirm that the component meets all applicable RoHS directives and halogen-free requirements for your assembly process. Ensure the SMAF package dimensions align with your PCB footprint design. Cross-reference the date code marking against your inventory management system to verify production timing.
Selection Notes
Select this component when a 50V blocking capability and 3A continuous current are required in a compact SMAF footprint. Consider its low forward voltage characteristics for applications prioritizing energy efficiency. Evaluate the thermal resistance values if operating near the upper temperature limits. Verify compatibility with automated assembly processes due to the tape and reel packaging options available.
Part Context
This part belongs to the B350AF-B360AF series of 3.0A Schottky barrier rectifiers from Diodes Incorporated. The series utilizes a molded plastic case with a matte tin annealed finish over a copper leadframe. The components are classified as Level 1 moisture sensitive devices per J-STD-020 standards. The product line emphasizes green manufacturing practices with antimony and halogen-free compounds.
Replacement Considerations
Direct substitutes include other 3A 50V Schottky rectifiers in the SMAF package. Verify equivalent VF and IR specifications to maintain circuit performance. Check for identical thermal resistance ratings to ensure reliable heat dissipation. Confirm mechanical compatibility with existing PCB pad layouts.
