B5819WT

Overview

The B5819WT is a surface-mount Schottky barrier diode manufactured by Shenzhen Slkormicro Semicon Co., Ltd. It features a maximum repetitive peak reverse voltage of 40 V and an average rectified output current of 1 A. The device utilizes a SOD-123 package, suitable for compact circuit designs. Key electrical characteristics include a forward voltage drop of 600 mV at 1 A and a reverse leakage current of 1 mA at 40 V. It operates within a junction temperature range of -55°C to 125°C.

Feature Summary

• Schottky barrier construction for low forward voltage drop
• High switching speed with negligible reverse recovery time
• Low power consumption and high efficiency
• Designed for polarity protection and free-wheeling applications

Applications

• Switch mode power supplies
• High frequency DC to DC converters
• Polarity protection circuits
• Free wheeling diodes in inductive loads

Procurement Notes

Verify the manufacturer designation as Shenzhen Slkormicro Semicon Co., Ltd. against the specific datasheet provided by the supplier. Confirm the package type is SOD-123 and that the part number suffix 'T' indicates tape and reel packaging if required for automated assembly. Ensure RoHS compliance status matches project requirements.

Selection Notes

Select this component for applications requiring fast switching and low conduction losses at moderate currents. The 40 V rating provides sufficient headroom for standard 5 V and 12 V systems. Consider the SOD-123 footprint constraints and thermal dissipation capabilities relative to the ambient operating conditions of the final assembly.

Part Context

This component belongs to the class of silicon Schottky barrier diodes designed for general-purpose rectification in low-voltage, high-frequency circuits. It serves as a surface-mount alternative to axial leaded equivalents, offering similar electrical performance in a smaller form factor suitable for modern PCB layouts.
