S3A Description

Short technical summary and product information.

The S3A is a general purpose rectifier diode manufactured by On Semiconductor. It is designed for standard rectification applications requiring a maximum DC reverse voltage of 50V and an average rectified current of 3A. The diode exhibits a typical forward voltage of 1.15V at 3A and a reverse recovery time of 1.5µs, classifying it as a standard recovery device (>500ns).

 

This diode is suitable for use in power supply rectification, freewheeling, and polarity protection circuits where moderate voltage and current ratings are sufficient. The standard recovery characteristic makes it appropriate for low-frequency applications where switching speed is not critical.

 

The S3A is offered in a surface mount DO-214AB (SMC) package, enabling automated assembly and space-efficient designs. It operates over a temperature range of -50°C to 150°C. The device is RoHS compliant and has an MSL rating of 1 (unlimited floor life).
