Overview
The BYS12-90-M3/TR 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 1.0 A and supports a peak forward surge current of 40 A. It operates within a junction and storage temperature range of -55 to +150 °C, housed in an SMA (DO-214AC) package.
Feature Summary
- Guardring structure provides enhanced overvoltage protection capabilities
- Low power losses and very low switching losses ensure high efficiency
- High surge capability accommodates transient load conditions
- Meets MSL level 1 per J-STD-020 with LF maximum peak of 260 °C
Applications
- High frequency inverters
- Switching power supplies
- Freewheeling diodes
- OR-ing diode circuits
- DC/DC converters
- Reverse battery protection
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging quantity and delivery mode. The base part number indicates halogen-free, RoHS-compliant construction. Confirm that the M3 suffix meets JESD 201 class 2 whisker test requirements if applicable to the design. Ensure the component matches the required SMA (DO-214AC) mechanical dimensions for automated placement compatibility.
Selection Notes
Select this component for applications requiring low forward voltage drop and fast switching characteristics. The 90 V rating suits low-voltage DC conversion systems. Verify thermal resistance values against the specific mounting condition, as junction-to-ambient resistance varies significantly based on PCB copper area and substrate material. Ensure the operating temperature remains within the specified -55 to +150 °C range.
Part Context
This device belongs to the BYS12 series of surface-mount Schottky barrier rectifiers from Vishay. It utilizes a guardring technology to improve ruggedness against overvoltage events. The M3 designation signifies compliance with RoHS directives and halogen-free material standards. The product is designed for automated assembly processes due to its low-profile package geometry.
Replacement Considerations
Cross-reference with other Vishay BYS12 variants or equivalent SMA-packaged Schottky rectifiers having matching 90 V and 1.5 A ratings. Verify pinout polarity and thermal characteristics before substitution.
FAQ
What is the purpose of the guardring in the BYS12-90-M3?
The guardring structure is included to provide overvoltage protection, enhancing the device's ruggedness.
Does the M3 suffix affect the electrical function of the diode?
No, the M3 suffix denotes environmental compliance (halogen-free, RoHS) and whisker test qualification; it does not change the electrical function.
