SK820LQ-TP

Single Diodes Overview

The SK820LQ-TP is a Schottky barrier rectifier manufactured by Micro Commercial Components (MCC). It features a single diode configuration in a DO-221AC surface-mount package. The device supports a maximum repetitive peak reverse voltage of 200 V and an average forward current of 5 A. Key electrical characteristics include a low forward voltage drop of 820 mV at rated current, a maximum reverse leakage current of 5 uA, and a non-repetitive peak forward surge current capability of 120 A. The component operates within a temperature range of -55 C to +175 C junction temperature.

Single Diodes Feature Summary

• Utilizes silicon Schottky barrier technology for high-efficiency rectification with minimal power loss.
• Engineered for high-speed switching applications due to ultra-low forward voltage drop characteristics.
• Designed for robust performance under thermal stress with extended maximum operating junction temperature.

Single Diodes Applications

• DC-to-DC converter circuits
• Power supply freewheeling diodes
• Reverse polarity protection systems

Single Diodes Procurement Notes

Verify the specific suffix 'Q' against the manufacturer's official datasheet to confirm packaging details such as reel size or tape width. Ensure the ordering quantity aligns with the manufacturer's standard factory pack quantities to avoid partial reel handling issues. Confirm RoHS compliance status directly from the product specification document prior to final procurement authorization.

Single Diodes Selection Notes

Select this component when a 5 A current rating and 200 V blocking voltage are required in a compact SMD form factor. The DO-221AC package offers a balance between current handling capacity and board space efficiency. Consider the 820 mV forward voltage drop for thermal management calculations in high-current designs. Verify that the 120 A surge current rating meets the inrush requirements of the target circuit application.

Single Diodes Part Context

This part belongs to the SK series of Schottky rectifiers from Micro Commercial Components. The series is characterized by low forward voltage and high surge current capability. The 'TP' suffix typically denotes a specific tape and reel packaging format compliant with industry standards for automated assembly processes.

Single Diodes Replacement Considerations

Consult official MCC substitution guides for direct equivalents. Generic replacements must match the 5 A current, 200 V voltage, and DO-221AC package constraints. Verify pinout compatibility and thermal resistance specifications before integrating alternative components into existing designs.
