The 1N4148 is a standard silicon switching signal diode. It is one of the most popular and long-lived switching diodes because of its dependable specifications and low cost. Its name follows the JEDEC nomenclature. The 1N4148 is useful in switching applications up to about 100 MHz with a reverse-recovery time of no more than 4 ns.
Absolute maximum ratings (stress ratings, consult datasheet for recommended ratings)
VRRM = 100 V (maximum repetitive reverse voltage)
IO = 200 mA (average rectified forward current)
IF = 300 mA (DC forward current)
If = 400 mA (recurring peak forward current)
IFSM = 1 A at 1 s pulse width; 4 A at 1 μs pulse width (non-repetitive peak forward surge current)
