Overview
The B120BE-13 is a Schottky barrier rectifier manufactured by Diodes Incorporated, housed in an SMB surface-mount package. It features a peak repetitive reverse voltage of 30 V and supports an average rectified output current of 1 A. The device exhibits a maximum forward voltage drop of 0.50 V at 1 A and +25°C, with a typical junction capacitance of 50 pF. Thermal resistance from junction to ambient is specified at 90 °C/W for the SMB case. Operating and storage temperature ranges extend from -55°C to +150°C.
Feature Summary
- Provides low forward voltage drop for improved efficiency and cooler operation
- Ensures excellent reverse leakage stability at high temperatures to prevent thermal runaway
- Constructed with molded plastic green molding compound that is halogen and antimony free
Applications
- Boost diode circuits
- Blocking diode applications
- Recirculating diode implementations
Procurement Notes
Verify the specific ordering suffix to confirm the SMB package configuration, as the AE variant utilizes an SMA package. Confirm RoHS compliance status and lead-free finish requirements against current manufacturing standards. Ensure the selected component meets the required thermal management specifications for the intended ambient operating conditions.
Selection Notes
Select this component when a 30 V blocking capability and 1 A continuous current rating are required in a compact SMB footprint. Consider the lower thermal resistance compared to the SMA version for better heat dissipation. Evaluate the forward voltage characteristics against system efficiency targets and ensure compatibility with standard surface-mount reflow soldering profiles.
Part Context
This part belongs to the B120AE-B140AE and B120BE-B140BE series of 1.0 A Schottky barrier rectifiers. The BE designation specifically identifies the SMB surface-mount package variant, distinguishing it from the SMA packaged AE series. Both series share identical electrical performance characteristics regarding voltage ratings and current handling capabilities.
