Working Principle

The TSP15U120S S1G is a Schottky-based rectifier diode, meaning it utilizes a Schottky barrier as opposed to a standard ohmic contact. This Schottky barrier causes electrons to tunnel across the barrier, allowing for a much lower forward voltage drop than on traditional rectifiers. This low voltage drop is what allows for increased efficiency, as it reduces power losses in the diode.

The TSP15U120S S1G has a maximum load current rating of 1A, with a maximum rated voltage of up to 60V. This makes it well-suited for a variety of different power supply applications. It is also designed to handle surge currents of up to 4A, ensuring that it can safely handle power surges without compromising its performance.

Furthermore, the TSP15U120S S1G is designed to be thermally stable, with a junction-to-case thermal resistance of up to 0.83°C/W. This is important in order to ensure that the diode can handle high-power applications without overheating and compromising its performance.
