1N4148 Description

Short technical summary and product information.

The 1N4148 from BKC is a silicon epitaxial planar diode, electrically equivalent to the 1N914. It is designed for extreme fast switching applications.

 

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 recovery time is as low as 4ns under specific conditions, making it suitable for high-frequency circuits.

 

This diode comes in a DO-35 (DO-204AH) case with a weight of approximately 105 mg. The cathode band is black. Packaging options include tape and reel or ammopack, with quantities of 10K per reel/ammopack and 50K per box.

 

Absolute maximum ratings include a reverse voltage of 75V and a peak forward surge current of 2A. The junction temperature can reach up to 175°C, with a storage temperature range of -65°C to +150°C.
