1N4148WT

1N4148WT Description

The 1N4148WT from Diotec Semiconductor is a high-performance surface-mount small-signal switching diode in a compact SOD-523 package. Designed for applications requiring fast switching and low leakage, it features a reverse voltage (Vr) of 80V, a forward current (Io) of 125mA, and an ultra-fast reverse recovery time (trr) of just 4ns. With a low forward voltage drop (1V @ 50mA) and minimal reverse leakage current (1µA @ 75V), this diode excels in precision circuits. Its 2pF junction capacitance (@ 0V, 1MHz) ensures minimal signal distortion, making it ideal for high-frequency applications.
