The SS310 is a Schottky diode with low power loss, high surge current capability. It is easy to handle and place, capsuled in a SOD-123 package. It sees versatile applications like polarity protection devices, DC/DC converters, free-wheeling devices, etc. It has a relatively faster switching time and can withstand a current up to 80A; therefore it is suitable for high-frequency switching circuits.

How to Use the SS310 Schottky Diode
The source is input from the left and output from the right, forming a BUCK (step-down) DC/DC conversion.
The source inputs from the right and outputs from the left, forming a BOOST (boost) DC/DC converter.
The SS310 diodes here are not needed in some cases, but they are connected in parallel with Q2, Q3 body diodes, which can improve the output current capacity (shared current).
As for the R-L series, the purpose is to eliminate the ring, of the switch node (VS1) and reduce the external interference.

SS310 Diode FAQ
1. What exactly is what is a Schottky diode to do?
Schottky diodes are utilized for higher frequencies due to their low voltage to turn on as well as their quick recovery times and minimal energy loss. Schottky diodes can be used for rectifying currents because of their rapid transition from conducting states to blocking.
2. Do I have to replace the Schottky diode by a normal diode?
In general in the event that the current rating and the voltage are similar, you’ll have a lower forward voltage drop. Schottky diodes, on contrary, aren’t available at high voltage ratings. Therefore, you might want to think about the SBS diode that has lower drop and can be found with higher ratings.
3. What other alternatives are available, aside for the diode SS310 to prevent through-holes and ensure the current capacity?
There are a variety of choices. For applications with low current look into BAT54 series, BAT54 series. For higher current, try the BAV99 series. BAV99 series. For higher current, you can go towards the SK series, as well as other parts of the SS series.
