Fast-Switching Rectifier diode (1N4148)

The 1N4148 is a standard silicon switching signal diode, renowned for its dependable specifications and low cost in electronic projects. It is suitable for switching applications up to approximately 100 MHz, featuring a maximum reverse-recovery time of 4 ns. Key electrical ratings include a maximum repetitive reverse voltage (VRRM) of 100 V and an average rectified forward current (IO) of 200 mA. Typically housed in a DO-35 glass axial package, this diode is commonly used for signal rectification, protection, and fast switching in low-current circuits.
