Single Diodes datasheet and documents for SB550
Single Diodes Overview
The SB550 is a Schottky barrier rectifier from the SB520-SB5100 series, manufactured by onsemi. It features a metal-to-silicon construction with majority carrier conduction for low power loss and high efficiency. The device provides an average forward current of 5.0 A at 75°C ambient temperature and withstands a maximum repetitive reverse voltage of 50 V. It exhibits a forward voltage of 0.67 V at 5.0 A and supports a non-repetitive peak forward surge current of 150 A. Packaged in DO-201AD, it operates within a junction temperature range of -50 to +150 °C.

Single Diodes Procurement Notes
Verify the specific part number against the official onsemi database, as Fairchild Semiconductor integration may have updated nomenclature. Ensure the ordering suffix matches current system requirements, noting that underscores in legacy Fairchild numbers are replaced by dashes. Confirm RoHS compliance status through official documentation before procurement.
Single Diodes Selection Notes
Select this component for applications requiring high efficiency and low forward voltage drop at 5.0 A. Consider the 50 V reverse voltage rating and 150 A surge capacity for appropriate circuit protection needs. Evaluate thermal resistance and derating curves for high ambient temperature environments to ensure reliable operation within specified limits.
Single Diodes Part Context
The SB550 belongs to the SB520-SB5100 series of Schottky Rectifiers originally developed by Fairchild Semiconductor. Following the acquisition, these products are managed under onsemi. This series offers various voltage ratings from 20 V to 100 V, all sharing similar package styles and current capabilities for versatile power management solutions.
Single Diodes Replacement Considerations
Other devices within the SB520-SB5100 series can replace the SB550 if voltage or current requirements differ. Verify pinout compatibility and thermal characteristics when substituting with equivalent Schottky rectifiers from other manufacturers.
