SKL110

Single Diodes Overview

The SKL110 is a surface-mount Schottky barrier rectifier diode manufactured by Diotec Semiconductor. It features an average forward current rating of 1 A and a repetitive peak reverse voltage of 110 V. The device utilizes a DO-214AA (SMB) package for SMD/SMT mounting. Key electrical characteristics include a maximum forward voltage of 0.85 V at 1 A, a typical junction capacitance of 17 pF at 25°C, and a thermal resistance from junction to ambient of 110 K/W on a PCB with 25 mm² copper pads. It operates within a temperature range of -50°C to +150°C.

Single Diodes Feature Summary

• Schottky barrier construction enables low forward voltage drop and fast switching speeds.
• Designed for high-frequency inverter, free-wheeling, and polarity protection applications.
• Compliant with RoHS standards and halogen-free manufacturing requirements.

Single Diodes Applications

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

Single Diodes Procurement Notes

Verify the specific suffix designation when ordering, as variants such as the -AQ version possess distinct leakage current specifications compared to standard grades. Confirm that the required component meets the intended reliability grade, noting that standard parts are designed for commercial and industrial applications rather than life-support systems. Ensure the selected part number matches the exact voltage and current ratings required for the target circuit design.

Single Diodes Selection Notes

Select this component for designs requiring a 1 A continuous current capability with a 110 V blocking voltage in a compact SMB package. Consider the typical junction capacitance and forward voltage characteristics for efficiency calculations in high-frequency switching environments. Evaluate the thermal resistance parameters against the expected ambient conditions and PCB copper pad dimensions to ensure adequate heat dissipation during operation.

Single Diodes Part Context

The SKL110 belongs to the SKL series of surface-mount Schottky barrier rectifiers produced by Diotec Semiconductor. This family includes various voltage ratings ranging from 12 V to 120 V, all sharing a common 1 A average forward current rating. The series is engineered for general-purpose rectification tasks where low power loss and rapid recovery are beneficial, utilizing standardized surface-mount footprints for automated assembly.

Single Diodes Replacement Considerations

SKL110-AQ serves as a verified alternative within the same product line, offering stricter leakage current limits suitable for automotive-grade requirements.
