1N4448 Description

Short technical summary and product information.

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.
