Overview
The B120-13 is a surface mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a maximum average forward rectified current of 1 A and a maximum repetitive peak reverse voltage of 20 V. The device utilizes a plastic SMB (DO-214AA) package with two pins. Key electrical characteristics include a low forward voltage drop of 500 mV at 1 A and a maximum non-repetitive peak surge current capability of 30 A. It operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- Schottky barrier construction for high switching efficiency
- Low forward voltage drop reduces power loss
- Plastic encapsulation meets UL flammability classification 94V-0
Applications
- High-frequency rectification in DC-DC converters
- Power supply input protection circuits
- Free-wheeling diodes in low voltage applications
Procurement Notes
Verify the specific datasheet revision corresponding to the ordering suffix '-13' to ensure compatibility with reel packaging specifications. Confirm that the component matches the standard SMB footprint dimensions required by the target PCB layout. Cross-reference the manufacturer's latest environmental compliance declarations against project requirements.
Selection Notes
Select this component when a low forward voltage drop is critical for system efficiency at 1 A loads. The 20 V rating provides sufficient margin for low-voltage rails while maintaining fast recovery characteristics. Ensure the application environment stays within the specified operating temperature range to maintain reliability.
Part Context
This part belongs to the B1xx series of Schottky rectifiers from Diodes Incorporated, designed for general-purpose surface mount applications. The series offers various voltage ratings to suit different circuit requirements while maintaining consistent mechanical and thermal performance profiles across the product line.
Replacement Considerations
Direct substitutes include the B120B-13 and B120AE-13, which share identical electrical ratings and package dimensions. Verify pinout orientation and marking codes when swapping between these variants to ensure correct circuit integration.
