1N4148 Overview

The 1N4148 is Vishay's silicon epitaxial planar small-signal diode in a DO-35 glass package, built for very fast switching. It handles 100 V repetitive reverse voltage and 300 mA continuous forward current with a reverse recovery time of 4 ns, and it is electrically equivalent to the 1N914.

Key Features

  • 100 V VRRM, 75 V VR
  • 300 mA continuous, 500 mA repetitive peak forward current
  • Reverse recovery time 4 ns max
  • Diode capacitance 4 pF max
  • VF 1 V max at 10 mA
  • DO-35 (DO-204AH) axial package; ordering codes 1N4148-TAP and 1N4148TR

Applications

  • Extreme fast switches
  • Signal steering and clamping
  • General-purpose small-signal rectification
