SK220LA

Single Diodes Overview

The SK220LA is a surface-mount Schottky rectifier diode manufactured by SMC Diode Solutions. It features a maximum DC reverse voltage (Vr) of 200 V and an average forward rectified current (Io) of 2 A. The device exhibits a maximum forward voltage (Vf) of 900 mV at 2 A and a reverse leakage current of 500 µA at 200 V. Junction capacitance is specified as 170 pF at 5 V and 1 MHz. It utilizes the DO-214AC (SMA) package and supports a junction temperature range from -55°C to 150°C.

Single Diodes Feature Summary

• Schottky barrier technology for low forward voltage drop and high efficiency
• Glass passivated junction for enhanced reliability and stability
• Surface mount SMA (DO-214AC) packaging for automated assembly

Single Diodes Applications

• DC-DC converters
• Free-wheeling diodes in power supplies
• Polarity protection circuits

Single Diodes Procurement Notes

Verify the specific suffix 'LA' against the manufacturer's official datasheet to confirm exact electrical tolerances and marking codes, as suffixes can denote specific binning or packaging variations. Ensure the component meets RoHS compliance requirements if mandated by your design specifications. Cross-reference the DigiKey part number 1655-SK220LATR-ND for accurate ordering details and availability status.

Single Diodes Selection Notes

Select this component when a 200 V reverse voltage rating and 2 A continuous current capacity are required in a compact SMA package. The Schottky technology offers faster switching speeds compared to standard silicon rectifiers, making it suitable for high-frequency applications. Consider the 900 mV forward voltage drop for thermal management calculations in low-voltage output stages.

Single Diodes Part Context

The SK220LA belongs to the SK2 series of Schottky rectifiers from SMC Diode Solutions. This series provides various voltage ratings while maintaining a consistent 2 A current capability and SMA footprint. The 'LA' suffix typically indicates specific manufacturing lot or packaging attributes within the SMA case style, distinguishing it from other variants like the standard SK220A.

Single Diodes Replacement Considerations

Direct substitutes include the SK220A from SMC Diode Solutions, which shares identical electrical parameters and package dimensions. Other manufacturers offering equivalent 200 V, 2 A SMA Schottky diodes may serve as alternatives, provided pinout compatibility and thermal characteristics match the original design requirements.
