The 1N4148 from Unitrode is a silicon epitaxial planar diode designed for fast switching applications. It is electrically equivalent to the 1N914 diode.
Key electrical characteristics include a repetitive peak reverse voltage of 100V and a forward continuous current of 300mA. The average forward current is rated at 150mA. Its reverse current is very low, measuring 25nA at 20V and 5μA at 75V. The diode capacitance is typically 4pF at 1MHz.
This diode is housed in a DO-35 (DO-204AH) case, weighing approximately 105mg. It is suitable for applications requiring extreme fast switching speeds. The diode features a black cathode band for identification.
Packaging options include tape and reel (10K per 14" reel) and ammopack (10K per ammopack), with a box quantity of 50K.
