Overview
The BYS10-45HE3_A/I is a surface-mount Schottky barrier rectifier manufactured by Vishay General Semiconductor. It features a maximum repetitive peak reverse voltage of 45 V and a maximum average forward rectified current of 1.5 A. The device operates within a junction temperature range of -65 °C to +150 °C and exhibits a maximum instantaneous forward voltage of 500 mV at 1.0 A. It is housed in an SMA (DO-214AC) package with matte tin-plated leads.
Feature Summary
- Guardring structure provides enhanced overvoltage protection capabilities
- AEC-Q101 qualified for automotive applications
- Low power losses and very low switching losses for high efficiency
- High surge capability suitable for demanding transient conditions
Applications
- Low voltage high frequency inverters
- Freewheeling circuits
- DC/DC converters
- Polarity protection applications
Procurement Notes
Verify the specific ordering code suffix against official documentation to confirm compliance status, as variations exist between commercial grade and AEC-Q101 qualified versions. Ensure that the requested component matches the exact part number specifications required for your design parameters before finalizing procurement.
Selection Notes
Select this component for designs requiring a compact SMA package with robust automotive qualification standards. The low forward voltage drop supports efficient power conversion in low voltage environments. Verify thermal management requirements based on the specified junction-to-lead and junction-to-ambient thermal resistance values for your specific mounting configuration.
Part Context
This component belongs to the BYS10 series of surface-mount Schottky barrier rectifiers from Vishay. The series includes variants with different reverse voltage ratings, specifically 25 V, 35 V, and 45 V. All members share identical physical dimensions and general electrical characteristics, differing primarily in their maximum repetitive peak reverse voltage limits.
Replacement Considerations
Direct substitutes include other BYS10-45 variants such as BYS10-45-E3/TR or BYS10-45-M3/TR. When replacing, ensure the alternative maintains the SMA (DO-214AC) footprint and meets the required AEC-Q101 qualification if automotive reliability is necessary for the application.
FAQ
What does the 'HE3' suffix indicate for this component?
The HE3 suffix denotes that the component is RoHS-compliant and AEC-Q101 qualified, making it suitable for automotive applications.
How is the cathode polarity identified on the package?
The cathode end is indicated by a color band printed on the surface of the SMA package.
