1N4148 Description

Short technical summary and product information.

The 1N4148 is a silicon epitaxial planar diode designed for extreme fast switching applications. It features a repetitive peak reverse voltage of 100V and a forward continuous current of 300mA.

 

With a typical forward voltage of 1V at 10mA and a reverse recovery time as low as 4ns, this diode is suitable for high-speed switching circuits. The DO-35 (DO-204AH) package allows for through-hole mounting.

 

Key electrical characteristics include a maximum forward voltage of 1V at 10mA, a maximum reverse leakage current of 25nA at 20V, and a diode capacitance of 4pF at 0V and 1MHz. The junction temperature can reach up to 175°C.

 

This diode is electrically equivalent to the 1N914 and is available in tape and reel or ammopack packaging options.
