S115FP

S115FP Description

The S115FP from onsemi is a high-performance Schottky diode designed for automotive-grade applications, offering a robust combination of 150V reverse voltage (Vr) and 1A average rectified current (Io). Packaged in a SOD123HE surface-mount form factor, this diode is optimized for fast recovery (<500ns) and low forward voltage drop (900mV @ 1A), making it ideal for high-efficiency power conversion circuits. With a reverse leakage current of just 50µA @ 150V and a low junction capacitance (32pF @ 4V, 1MHz), the S115FP ensures minimal power loss and superior switching performance.
