What the 1SS181 family does
The 1SS181 is a fast switching diode in the SOT-23 package, designed for small signal switching and ultra high speed applications. It handles a maximum repetitive peak reverse voltage of 80 V and supports an average forward rectified current of 100 mA. The device features a reverse recovery time under 4 ns, a power dissipation of 150 mW, and a non-repetitive peak forward surge current of 2.0 A. Its low capacitance and fast switching characteristics make it suitable for high-frequency circuits requiring rapid turn-on and turn-off speeds while maintaining high stability and reliability across a wide temperature range.
