B5819XP-TP

Overview

The B5819XP-TP is a single-element silicon Schottky barrier rectifier manufactured by Micro Commercial Components. It features an average forward current of 700 mA and a repetitive peak reverse voltage of 40 V. The device exhibits a maximum forward voltage drop of 550 mV at rated current and a reverse leakage current of 50 uA. It supports a forward surge current of 5 A and operates within a junction temperature range up to +125 C. Power dissipation is rated at 150 mW, and the component is housed in an FBP-02L-2 surface-mount package.

Feature Summary

• Utilizes silicon Schottky technology for low forward voltage drop and negligible switching losses
• Designed for high-frequency applications with avalanche capability specified
• Surface-mount construction in a compact FBP-02L-2 package

Applications

• Switch mode power supplies
• High frequency DC to DC converters
• Low voltage high frequency inverters
• Free wheeling diodes
• Polarity protection circuits

Procurement Notes

Verify the specific suffix XP against official datasheets to confirm the FBP-02L-2 package type, as MCC utilizes various suffixes for different form factors. Confirm RoHS compliance status through the manufacturer's latest documentation. Check for obsolescence notices or product change notifications (PCN) prior to final design approval. Ensure thermal management aligns with the 150 mW power dissipation rating under expected operating conditions.

Selection Notes

Select this component when a surface-mount Schottky rectifier with a 40 V rating and approximately 700 mA continuous current capacity is required. Compare the 550 mV forward voltage against alternatives like the SM5819PL-TP if lower loss is critical. Consider the FBP-02L-2 footprint constraints during PCB layout. Verify that the 5 A surge current rating meets transient requirements for the target application circuit.

Part Context

This part belongs to the B5819 series of Schottky rectifiers from Micro Commercial Components. It shares electrical characteristics with other variants such as the B5819WS-TP but differs in packaging. The series is designed for general-purpose rectification in low-voltage, high-frequency environments. MCC offers multiple package options including SOD-323 and DFN styles for the same electrical specification.
