SK39AHM2G

Single Diodes Overview

The SK39AHM2G is a single-element Schottky barrier rectifier manufactured by Taiwan Semiconductor. It utilizes silicon technology and is housed in the DO-214AC (SMA) surface-mount package with two terminals. The device is rated for a maximum repetitive peak reverse voltage of 90V and an average forward rectified current of 3A. Key electrical specifications include a maximum non-repetitive peak forward surge current of 100A, a maximum DC reverse leakage current of 30µA, and a maximum forward voltage drop of 0.79V at rated conditions.

Single Diodes Feature Summary

• Low power loss characteristics designed to enhance overall system efficiency
• Guardring structure incorporated for enhanced overvoltage protection capabilities
• High surge current capability suitable for demanding transient conditions
• Ideal for automated placement processes due to standardized surface mount packaging

Single Diodes Applications

• General purpose rectification in electronic circuits
• Free wheeling diode applications in inductive load management
• Efficiency-critical power supply designs requiring low forward voltage drop

Single Diodes Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the received parts match the specific SK39AHM2G designation and DO-214AC package type. Ensure compliance with RoHS Directive 2011/65/EU requirements and WEEE 2002/96/EC standards as documented in the official datasheet before integration into production.

Single Diodes Selection Notes

Select this component when a 3A Schottky rectifier with a 90V reverse voltage rating is required in a compact SMA package. Consider the 0.79V maximum forward voltage for thermal management calculations. Evaluate the 100A surge current rating against potential inrush currents in the target application to ensure adequate safety margins during startup or fault conditions.

Single Diodes Part Context

This device belongs to the SKxAH series of surface mount Schottky barrier rectifiers from Taiwan Semiconductor. The series offers various voltage ratings ranging from 20V to 200V while maintaining consistent 3A current handling capabilities. The SK39AHM2G specifically addresses applications needing 90V blocking voltage within the standard SMA footprint, providing a balance between performance and board space efficiency.

Single Diodes Replacement Considerations

Cross-reference with other SK39 variants such as SK39A or SK39AH depending on specific suffix requirements. Verify pinout compatibility with DO-214AC packages when substituting with equivalent Schottky diodes from other manufacturers. Ensure replacement parts meet the same 3A current and 90V voltage specifications.
