The BYS12-90-E3/TR3 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 and operates within a junction temperature range of -55 °C to +150 °C. The component is housed in a low-profile SMA (DO-214AC) package.
Verify the specific ordering code suffix against official documentation to confirm compliance status, qualification level, and delivery mode. Confirm that the requested variant matches the required RoHS compliance and automotive qualification standards before procurement.
Select this component for applications requiring efficient rectification in compact designs. Ensure the operating voltage does not exceed the 90 V rating and verify thermal management requirements align with the specified thermal resistance values for the target mounting conditions.
This part belongs to the BYS12 series of surface-mount Schottky barrier rectifiers from Vishay. The series utilizes a guardring technology to improve ruggedness and reliability under transient voltage conditions compared to standard structures.
Check datasheets for alternative Schottky rectifiers offering compatible voltage and current ratings within the SMA (DO-214AC) package. Verify pinout compatibility and thermal characteristics before substitution.
The guardring provides overvoltage protection, enhancing the device's ruggedness and reliability during transient events.
Standard versions are commercial grade. Automotive-grade variants are available with the HE3 suffix and are AEC-Q101 qualified.
