About the 1N4148 Diode

The 1N4148 diode is a fast, standard small signal silicon diode with high conductance used in signal processing. Its name follows the JEDEC nomenclature. The diode 1N4148 is generally available in a DO-35 glass package and is very useful at high frequencies with a reverse recovery time of no more than 4ns. This permits rectification and detection of radio frequency signals very effectively, as long as their amplitude is above the forward conduction threshold of silicon (around 0.7V) or the diode is biased.

Specification

  • VRRM = 100V (Maximum Repetitive Reverse Voltage)
  • IO = 200mA (Average Rectified Forward Current)
  • IF = 300mA (DC Forward Current)
  • IFSM = 1.0 A (Pulse Width = 1 sec), 4.0 A (Pulse Width = 1 uSec) (Non-Repetitive Peak Forward Surge Current)
  • PD = 500 mW (power Dissipation)
  • TRR < 4ns (reverse recovery time)
