Overview
The B120B-13 is a Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single element silicon construction housed in an SMB (DO-214AA) surface-mount package with two pins. The device supports a maximum repetitive peak reverse voltage of 20 V and an average forward rectified current of 1 A. Key electrical characteristics include a maximum DC reverse current of 5 uA at rated blocking voltage and a typical forward voltage drop of 500 mV when conducting 1 A.
Feature Summary
- Schottky barrier technology for low forward voltage drop
- Silicon planar construction for high reliability
- Surface-mount SMB package design
Applications
- Polarity protection circuits
- Free wheeling diode applications
- Low voltage high frequency inverters
Procurement Notes
Verify the specific ordering suffix to confirm the reel quantity and tape specifications, as variations exist within the product line. Ensure the component meets RoHS compliance requirements if mandated by the assembly process. Cross-reference the manufacturer datasheet for detailed thermal derating curves and moisture sensitivity levels before finalizing procurement plans.
Selection Notes
Select this component for designs requiring efficient rectification with minimal power loss due to its low forward voltage characteristic. The SMB package is suitable for automated surface-mount assembly processes. Consider the 20 V reverse voltage rating to ensure adequate margin against transient spikes in the target circuit application.
Part Context
This part belongs to the B1xxxB series of Schottky rectifiers from Diodes Incorporated. The series offers various voltage ratings including 20 V, 30 V, and 40 V options. These devices are designed for general-purpose rectification tasks where speed and efficiency are prioritized over high voltage handling capabilities.
Replacement Considerations
Equivalent parts include the B120B-13-F variant which shares identical electrical specifications. Other manufacturers produce compatible 1 A 20 V Schottky rectifiers in the SMB package, such as those from Weitron Technology or CTC, provided pinout and thermal parameters match.
