SBL1050

Single Diodes Overview

The SBL1050 is a discontinued single-phase Schottky barrier rectifier manufactured by Diodes Incorporated. It features a TO-220AC case with a peak repetitive reverse voltage of 50V and an average rectified output current of 10A at a case temperature of 95°C. The device utilizes guard ring die construction for transient protection, offering low forward voltage drop and high surge capability. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 250A and a typical junction capacitance of 700pF.

Single Diodes Procurement Notes

This component is officially marked as obsolete and discontinued by the manufacturer. No alternate part numbers are provided in the documentation. Procurement must rely on secondary market channels or equivalent replacements from other manufacturers. Verify datasheet revisions and specific lot markings when sourcing from distributors to ensure authenticity and traceability.

Single Diodes Selection Notes

Designers should consider the 50V reverse voltage rating and 10A continuous current capacity when selecting this component. Note that thermal resistance is specified at a case temperature of 95°C. Current derating is required for capacitive loads, specifically a 20% reduction. Ensure adequate heatsinking to maintain junction temperatures within the -65 to +150°C operating range.

Single Diodes Part Context

The SBL1050 belongs to the SBL1030-SBL1060 series of 10A Schottky barrier rectifiers. These devices share identical mechanical and thermal characteristics, differing primarily in their maximum repetitive reverse voltage ratings. The series was designed for general-purpose rectification in power supplies and DC-DC converters requiring fast switching speeds.

Single Diodes Replacement Considerations

No official substitute part numbers are listed in the datasheet. Designers must identify cross-compatible components based on matching electrical parameters (50V, 10A) and physical footprint (TO-220AC). Verify that any replacement maintains similar forward voltage and reverse leakage characteristics.

Single Diodes FAQ
