The 1N4148 is a standard silicon switching diode. Its name follows the JEDEC nomenclature. The 1N4148 has a DO-35 glass package and is very useful at high frequencies with a reverse recovery time of no more than 4ns. It was second sourced by many manufacturers; Texas Instruments listed their version of the device in an October 1966 data sheet. [1]
The 1N914 is an equivalent diode (meaning it has the same specifications, but some manufacturers use one part number or the other).[2] These devices types have an enduring popularity in low-current applications.[3][4]
Specifications:
- 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)
