SK52B M4G

Single Diodes Overview

The SK52B M4G is a single-element silicon Schottky rectifier manufactured by Taiwan Semiconductor Corporation. It features a maximum average forward rectified current of 5 A and a repetitive peak reverse voltage rating of 20 V. The device utilizes the DO-214AA (SMB) surface-mount package. Key electrical parameters include a maximum forward voltage of 550 mV at 5 A, a non-repetitive peak forward surge current of 120 A, and a maximum reverse leakage current of 500 uA. The component operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

• Utilizes silicon Schottky barrier technology for low forward voltage drop and high efficiency.
• Designed for surface mount applications with extremely low thermal resistance.
• Capable of high-temperature soldering processes up to 250°C for 10 seconds at terminals.

Single Diodes Applications

• General purpose rectification in power supply circuits
• Free-wheeling diodes in inductive load switching
• Reverse polarity protection in DC systems

Single Diodes Procurement Notes

Verify the specific ordering suffix M4G against the manufacturer's latest datasheet to confirm packaging details and compliance status. Ensure the component meets RoHS3 requirements if applicable to your design specifications. Cross-reference the part number with official distributor catalogs to validate authenticity and current production status before finalizing procurement.

Single Diodes Selection Notes

Select this component when a 5 A current rating and 20 V blocking voltage are required in a compact SMB package. Consider the low forward voltage characteristic for improved efficiency in low-voltage applications. Verify that the thermal management strategy accommodates the specified junction temperature limits and thermal resistance values under expected operating conditions.

Single Diodes Part Context

This part belongs to the SK52B series of Schottky rectifiers from Taiwan Semiconductor. The series offers various voltage ratings ranging from 20 V to 100 V in the same DO-214AA package family. These devices are designed to replace bulkier through-hole rectifiers in modern surface-mount designs, providing similar performance characteristics in a smaller footprint.

Single Diodes Replacement Considerations

Compatible replacements include other 5 A, 20 V Schottky diodes in the DO-214AA package such as the SK52 from Micro Commercial Components. Verify pinout compatibility and ensure equivalent or superior electrical ratings for forward current, reverse voltage, and thermal performance before substitution.
