Overview
The B120-E3/5AT is a surface-mount Schottky barrier rectifier manufactured by Vishay General Semiconductor. It features a maximum average forward rectified current of 1.0 A and a maximum repetitive peak reverse voltage of 20 V. The device exhibits a maximum instantaneous forward voltage of 0.52 V at 1.0 A and a peak forward surge current capability of 30 A. It operates within a junction temperature range of -65 °C to +125 °C and utilizes the SMA (DO-214AC) package.
Feature Summary
- Guardring structure provides overvoltage protection
- Low forward voltage drop for high efficiency
- High surge current capability
- Meets MSL level 1 per J-STD-020
Applications
- Low voltage, high frequency inverters
- Freewheeling applications
- DC/DC converters
- Polarity protection circuits
Procurement Notes
Verify that the component matches the specific Vishay datasheet document number 88946 revision dated 08-Jan-2021. Confirm the ordering suffix /5AT corresponds to the 7500-unit base quantity in a 13-inch diameter plastic tape and reel delivery mode. Ensure compliance with RoHS requirements and check material categorization definitions on the manufacturer website.
Selection Notes
Select this component for low voltage, high frequency applications requiring efficient rectification. The SMA (DO-214AC) package is suitable for automated placement. Note that these devices are not AEC-Q101 qualified. Validate thermal resistance parameters against specific PCB copper pad areas during design.
Part Context
This part belongs to the B1xx-E3 series of surface-mount Schottky barrier rectifiers from Vishay General Semiconductor. The series includes variants with different reverse voltage ratings such as B130, B140, B150, and B160. All share similar mechanical data and packaging options, differing primarily in their maximum repetitive peak reverse voltage specifications.
Replacement Considerations
Direct substitutes include other Vishay parts within the same series: B130-E3/5AT, B140-E3/5AT, B150-E3/5AT, and B160-E3/5AT. These alternatives offer higher reverse voltage ratings while maintaining identical current and package characteristics.
FAQ
Is the B120-E3/5AT qualified for automotive applications?
No, the datasheet explicitly states that these devices are not AEC-Q101 qualified.
What does the E3 suffix indicate regarding the terminals?
The E3 suffix indicates matte tin plated leads that are solderable per J-STD-002 and JESD 22-B102 standards.
