B190B-13

Overview

The B190B-13 is a Schottky barrier rectifier manufactured by Diodes Incorporated. It features a maximum DC reverse voltage (Vr) of 90 V and an average forward rectified current (Io) of 1 A. The device utilizes the SMB (DO-214AA) surface-mount package. Key electrical characteristics include a maximum forward voltage (Vf) of 790 mV at 1 A, a reverse leakage current of 500 µA at 90 V, and a junction capacitance of 80 pF at 4 V and 1 MHz. The operating junction temperature range spans from -65°C to 150°C.

Feature Summary

• Schottky barrier technology for low power loss and high efficiency
• Guard ring die construction for transient protection
• Suitable for polarity protection applications

Applications

• Low voltage, high frequency inverters
• Free wheeling diodes
• Polarity protection circuits

Procurement Notes

Verify component authenticity through authorized channels as DigiKey lists this specific part number as discontinued. Confirm RoHS compliance status with the manufacturer, as documentation indicates potential non-compliance for this specific suffix. Ensure replacement parts match the SMB package and electrical ratings if sourcing alternatives.

Selection Notes

Select this component for designs requiring a 90 V reverse voltage rating and 1 A continuous current capability in a compact SMB package. Consider the 790 mV forward voltage drop for thermal management calculations. Verify that the 500 µA reverse leakage current meets system requirements at maximum operating temperatures.
