Overview
The BYS11-90HE3_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 low instantaneous forward voltage of 750 mV at 1.0 A and supports a peak forward surge current of 40 A. It operates within a junction temperature range of -55 to +150 °C and utilizes an SMA (DO-214AC) package.
Feature Summary
- Guardring structure provides enhanced overvoltage protection capabilities
- Low power losses and very low switching losses for high efficiency
- High surge capability suitable for demanding transient conditions
Applications
- High frequency inverters
- Switching power supplies
- Freewheeling diodes
- DC/DC converters
- Reverse battery protection
Procurement Notes
Verify the specific ordering code suffix against official documentation to confirm qualification status. The HE3 suffix indicates RoHS compliance and AEC-Q101 automotive qualification, whereas standard E3 suffixes denote commercial grade availability. Ensure the requested revision code matches the required manufacturing batch specifications before finalizing procurement orders.
Selection Notes
Select this component for applications requiring low forward voltage drop and high efficiency in compact designs. The SMA package is optimized for automated placement processes. Verify thermal resistance requirements against the specific mounting pad layout, as junction-to-ambient resistance varies significantly based on copper area and substrate material used in the design.
Part Context
This part belongs to the BYS11 series of surface-mount Schottky barrier rectifiers from Vishay. The series offers various voltage ratings within the same physical footprint to simplify supply chains. The HE3 variant specifically targets automotive and high-reliability markets by meeting stringent AEC-Q101 standards while maintaining environmental compliance.
Replacement Considerations
Direct substitutes include other Vishay BYS11 series parts with matching voltage and current ratings, such as BYS11-60 or BYS11-100, provided the reverse voltage requirements align. Cross-manufacturer replacements must match the SMA (DO-214AC) package dimensions and ensure equivalent forward voltage and reverse leakage characteristics.
