Single Diodes Procurement Notes

Verify the specific reverse voltage rating (50V, 100V, 200V, or 400V) required for your application, as the SF21 series encompasses multiple voltage variants. Confirm that the package type matches your PCB footprint requirements. Ensure the supplier provides documentation confirming the glass-passivation process and compliance with relevant safety standards for the intended end-use environment.

Single Diodes Selection Notes

Select this component when a robust, cost-effective solution for medium-current rectification is needed. The super-fast recovery characteristic makes it preferable over standard rectifiers in high-frequency switching applications. Consider the thermal management requirements based on the expected forward current and ambient temperature conditions to ensure long-term reliability within the specified operating range.

Single Diodes Part Context

This part belongs to the SF21 series of super-fast rectifiers from Taiwan Semiconductor. The 'G' suffix typically denotes the glass passivation feature, while 'H' may indicate specific packaging or tape-and-reel configuration details depending on the manufacturer's coding scheme. This series is widely used in industrial and consumer electronics due to its balance of performance and cost-effectiveness.

Single Diodes Replacement Considerations

Direct replacements include other 2A super-fast rectifiers with similar voltage ratings and package types, such as those from Rectron, Mospec, or Jinan Gude Electronic. Ensure any substitute maintains the same or better reverse recovery time and forward voltage characteristics to preserve circuit performance.
