SK55B M4G

Single Diodes Overview

The SK55B M4G is a Schottky barrier rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a 50 V reverse voltage rating and a 5 A average forward current capability. The device utilizes the DO-214AA (SMA) surface-mount package, designed for compact circuit layouts. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 120 A and a low forward voltage drop to minimize power loss. The component supports a maximum operating junction temperature of 150 °C and is RoHS compliant.

Single Diodes Feature Summary

• Schottky barrier construction for high switching efficiency
• Low forward voltage drop reduces conduction losses
• Surface-mount SMA (DO-214AA) package for automated assembly

Single Diodes Applications

• High-frequency DC-DC converters
• Free-wheeling rectification in power supplies
• Polarity protection circuits

Single Diodes Procurement Notes

Verify the manufacturer marking on the component body matches Taiwan Semiconductor specifications. Confirm the package type is DO-214AA and that the part is lead-free and RoHS compliant. Ensure the ordering suffix corresponds to the required tape-and-reel quantity if applicable. Cross-reference the date code with current production status to avoid obsolete stock.

Single Diodes Selection Notes

Select this component when a low-loss, fast-switching rectifier is required in space-constrained designs. The 5 A current rating suits moderate-power applications. Consider the 50 V reverse voltage limit against peak inverse voltages in the circuit. The SMA package offers a balance between thermal performance and board area efficiency compared to larger through-hole alternatives.
