1N4148 Description

Short technical summary and product information.

The 1N4148 is a silicon epitaxial planar diode designed for extreme fast switching applications. It is packaged in a DO-35 (DO-204AH) case and features a black cathode band.

 

Key electrical characteristics include a repetitive peak reverse voltage of 100V and a reverse voltage of 75V. The peak forward surge current is rated at 2A for a 1μs pulse, with a forward continuous current of 300mA and an average forward current of 150mA. The diode exhibits a typical forward voltage of 1V at 10mA and a low reverse current of 25nA at 20V.

 

Thermal specifications include a maximum junction temperature of 175°C and a storage temperature range of -65°C to +150°C. The power dissipation is 500mW at TL ≤ 25°C. The diode capacitance is typically 4pF at 1MHz.

 

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