SK59B M4G

Single Diodes Overview

The SK59B M4G is a silicon Schottky rectifier manufactured by Taiwan Semiconductor, designed for surface-mount applications in the DO-214AA (SMA) package. It features a single diode configuration with a maximum repetitive peak reverse voltage of 90 V and an average forward current rating of 5 A. The device exhibits a low forward voltage drop of 850 mV at rated current and supports a non-repetitive peak forward surge current of 120 A. Operating reliably within a temperature range of -55°C to +150°C junction temperature, it meets AEC-Q101 automotive qualification standards.

Single Diodes Feature Summary

• Utilizes silicon Schottky barrier technology to achieve low power loss and high efficiency during rectification.
• Engineered with a molded plastic outline compliant with standard surface-mount mounting styles for automated assembly.
• Certified to AEC-Q101 standards, ensuring reliability and performance consistency suitable for demanding automotive environments.

Single Diodes Applications

• Automotive electronics requiring AEC-Q101 qualified components
• General-purpose rectification in DC-DC converters
• Free-wheeling diodes in inductive load circuits

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure that the requested variant matches the required voltage and current ratings for the target application. Confirm RoHS and REACH compliance status directly with the supplier or original manufacturer documentation prior to procurement.

Single Diodes Selection Notes

Select this component when a 5 A current capacity and 90 V blocking voltage are required in a compact SMA footprint. The AEC-Q101 qualification makes it appropriate for automotive systems where long-term reliability under thermal stress is critical. Consider the 850 mV forward voltage drop for thermal management calculations in high-efficiency power supply designs.

Single Diodes Part Context

This part belongs to the SKxxB series of Schottky rectifiers from Taiwan Semiconductor, which offers various voltage ratings within the same physical package family. The 'M4G' suffix typically denotes specific packaging or environmental compliance attributes defined by the manufacturer. This series is widely used in consumer and industrial electronics for efficient power conversion.

Single Diodes Replacement Considerations

Direct substitutes include other 5A 90V Schottky diodes in the DO-214AA package such as the SS59 or equivalent parts from other manufacturers, provided they meet the same electrical and thermal specifications.
