Overview
The BYS11-90HE3_A/I is a surface-mount Schottky barrier rectifier manufactured by Vishay General Semiconductor. It features a maximum average forward rectified current of 1.5 A and a maximum repetitive peak reverse voltage of 90 V. The device exhibits a low instantaneous forward voltage of 750 mV at 1.0 A, ensuring high efficiency and minimal power losses. It is housed in an SMA (DO-214AC) package with matte tin-plated leads. The component is AEC-Q101 qualified for automotive applications and meets RoHS compliance standards.
Feature Summary
- Guardring structure provides enhanced overvoltage protection capabilities
- Trench MOS Schottky technology enables very low switching losses and high surge capability
- Low profile SMA package design is optimized for automated placement processes
Applications
- High frequency inverters
- Switching power supplies
- Freewheeling diodes
- DC/DC converters
- Reverse battery protection circuits
Procurement Notes
Verify the specific ordering code suffix to confirm the required packaging quantity and reel diameter. Ensure the HE3 designation aligns with automotive qualification requirements if applicable. Confirm that the SMA package dimensions match the target PCB footprint layout. Validate material categorization and environmental compliance against project specifications before finalizing procurement orders.
Selection Notes
Select this component when low forward voltage drop and high efficiency are critical for thermal management. The 90 V rating suits low-voltage DC systems requiring robust reverse blocking. Consider the SMA package size for space-constrained designs. Verify junction temperature limits under expected load conditions to ensure reliable operation within the specified -55 °C to +150 °C range.
Part Context
This part belongs to the BYS11 series of surface-mount Schottky barrier rectifiers from Vishay. The series utilizes Trench MOS technology to achieve superior performance compared to standard Schottky diodes. The HE3 variant specifically denotes RoHS compliance and AEC-Q101 qualification for automotive use. The SMA package offers a compact form factor suitable for modern electronic assemblies.
Replacement Considerations
Direct substitutes must match the 1.5 A current rating, 90 V reverse voltage, and SMA package. Verify equivalent forward voltage characteristics and thermal resistance values. Ensure any replacement also meets AEC-Q101 requirements if used in automotive contexts. Check polarity marking conventions to prevent installation errors.
