1N4148 Description

Short technical summary and product information.

The 1N4148 from Philips is a silicon epitaxial planar diode designed for high-speed switching applications. It offers a repetitive peak reverse voltage of 100V and a maximum forward continuous current of 300mA, with an average forward current of 150mA.

This diode has a fast switching speed, with a reverse recovery time as low as 4ns under specific conditions. Its electrical characteristics include a typical forward voltage of 1V at 10mA and a typical diode capacitance of 4pF at 0V and 1MHz. The operating junction temperature can reach up to 175°C.

Packaged in a DO-35 (DO-204AH) case, the 1N4148 is suitable for through-hole mounting. It is often used in extreme fast switching circuits where rapid response times are critical. The cathode band is black.

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