BYS12-90HE3_A/H

Overview

The BYS12-90HE3_A/H is a surface-mount Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 90 V and a maximum average forward rectified current of 1.5 A. The device exhibits a maximum instantaneous forward voltage of 750 mV at an applied forward current of 1.0 A. It supports a peak forward surge current of 40 A under standard test conditions. The component operates within a junction and storage temperature range from -55 °C to +150 °C. It is housed in an SMA (DO-214AC) package.

Feature Summary

• Guardring structure provides enhanced overvoltage protection capabilities
• Optimized for automated placement with a low profile package design
• Delivers high efficiency through very low switching losses and power dissipation
• Qualified for automotive applications according to the AEC-Q101 standard

Applications

• High frequency inverters
• Switching power supplies
• Freewheeling diodes
• OR-ing diode circuits
• DC/DC converters
• Reverse battery protection

Procurement Notes

Verify that the specific ordering code matches the required qualification level, as the HE3 suffix indicates AEC-Q101 automotive qualification. Confirm the package type corresponds to SMA (DO-214AC). Ensure compliance with RoHS directives and material categorization requirements defined in the manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits requiring a 90 V reverse voltage rating and 1.5 A continuous forward current capability. The low forward voltage drop makes it suitable for high-efficiency power conversion applications. Verify thermal management requirements against the specified thermal resistance values for the chosen mounting configuration on the PCB.

Part Context

This part belongs to the BYS12 series of surface-mount Schottky barrier rectifiers produced by Vishay General Semiconductor. The series utilizes a guardring technology to improve ruggedness against transient overvoltages. The HE3 designation specifically denotes a lead-free, halogen-ban compliant variant that meets automotive reliability standards.

Replacement Considerations

Direct substitutes include other Vishay SMA packaged Schottky rectifiers with equivalent or higher voltage and current ratings, such as the BYS12-100HE3_A/H. Cross-manufacturer replacements must match the DO-214AC footprint and ensure comparable forward voltage and reverse leakage characteristics.
