BYS12-90-M3/TR3

Overview

The BYS12-90-M3/TR3 is a surface-mount Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a single circuit configuration housed in an SMA (DO-214AC) package. The device supports a maximum repetitive peak reverse voltage of 90 V and a maximum average forward rectified current of 1.5 A. It exhibits a maximum instantaneous forward voltage of 750 mV at 1.0 A and can withstand a peak forward surge current of 40 A. The component operates within a junction and storage temperature range of -55 °C to +150 °C.

Procurement Notes

Verify the specific ordering suffix matches the required delivery mode, as TR indicates 1800 units on a 7-inch reel while TR3 indicates 7500 units on a 13-inch reel. Confirm compliance requirements such as halogen-free status and RoHS adherence. Ensure the base part number corresponds to commercial grade specifications unless otherwise specified. Validate that the M3 suffix meets JESD 201 class 2 whisker test standards for your application needs.

Selection Notes

Select this component for applications requiring low profile packaging ideal for automated placement. Consider the thermal resistance characteristics when designing heat dissipation strategies, noting values vary based on mounting conditions. Evaluate the forward voltage drop and reverse leakage current against system efficiency targets. Ensure the 90 V rating accommodates peak reverse voltages in the target circuit design.

Part Context

This component belongs to the BYS12 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 matte tin plated leads solderable per JESD 22-B102 standards. Polarity is indicated by a color band denoting the cathode end on the SMA package.

Replacement Considerations

Cross-reference with other Vishay SMA packaged Schottky diodes sharing identical electrical ratings. Verify pinout compatibility and thermal performance metrics before substitution. Ensure any alternative component meets the same MSL level and material categorization requirements.

FAQ
