Procurement Notes
Verify the specific ordering suffix to confirm the reel diameter and base quantity. The TR3 designation indicates a 13-inch diameter plastic tape and reel with a base quantity of 7500 units. Confirm that the component meets halogen-free and RoHS compliance requirements as specified for the M3 series. Ensure the application environment remains within the -55 to +150 °C junction temperature range.
Selection Notes
Select this component for applications requiring a compact surface-mount Schottky rectifier with low forward voltage drop. The SMA package is suitable for automated placement processes. Consider the thermal resistance characteristics when designing heat dissipation paths. Verify that the 90 V reverse voltage rating exceeds the maximum expected operating voltage in the circuit.
Part Context
This part belongs to the BYS11 series of surface-mount Schottky barrier rectifiers from Vishay. The M3 suffix denotes a lead-free, halogen-free product compliant with RoHS directives. The device utilizes a guardring technology to improve ruggedness against transient overvoltage events compared to standard structures.
Replacement Considerations
Direct replacements must match the SMA (DO-214AC) package, 90 V reverse voltage, and 1.5 A average forward current ratings. Verify that substitute components offer comparable forward voltage characteristics and thermal performance. Ensure any alternative parts also meet the required MSL level and material categorization standards.
FAQ
What does the M3 suffix indicate for this component?
The M3 suffix indicates that the device is halogen-free, RoHS-compliant, and commercial grade. It also signifies that the terminals are matte tin plated and the component meets the JESD 201 class 2 whisker test.
How is polarity identified on the BYS11-90-M3/TR3?
Polarity is identified by a color band on the component body, which denotes the cathode end.
