The 1N4448 is a standard small-signal switching diode manufactured by On Semiconductor. It is designed for general-purpose rectification and switching applications requiring up to 100V reverse voltage and 200mA average forward current.
Key electrical specifications include a forward voltage of 1V at 100mA, reverse leakage current of 0.025µA at 20V, and a fast reverse recovery time of 4ns. The device also features a low junction capacitance of 2pF at 0V and 1MHz, making it suitable for high-speed switching circuits.
The diode is housed in a DO-204AH (DO-35) axial-lead package, supporting through-hole mounting. It can operate over a junction temperature range of -55°C to 175°C and has a maximum power dissipation of 500mW. Storage temperature range extends from -65°C to 200°C.
This part is commonly used in signal processing, protection circuits, and low-power rectification. It is a direct alternative to the 1N4148 and 1N914 diodes, sharing the same datasheet and electrical characteristics.
The maximum repetitive reverse voltage (VRRM) is 100V.
The average rectified forward current (Io) is 200mA.
The forward voltage (Vf) is 1V at a forward current of 100mA.
The reverse recovery time (trr) is 4ns.
The 1N4448 is available in a DO-204AH (DO-35) axial-lead through-hole package.
The junction operating temperature range is -55°C to 175°C.
The reverse leakage current is 0.025µA at a reverse voltage of 20V.
