The current flow regulator has two main pins: the anode and the cathode. Their uses are as follows:

Anode– It’s the terminal via which continuous current enters the diode
Cathode– Electrical current leaves the diode via the cathode.
Often, the cathode end features a color band to distinguish it from the anode. Thus electronic hobbyists can quickly tell the cathode as it features a silver band.
It has a 1A average forward current and a 5uA reverse current.
Also, the diode has a 30A non-repetitive peak current and 100V peak repetitive reverse voltage.
Further, it comes in a DO-41 Package type and features a 70V RMS (Root Mean Square) reverse voltage. But, it is also possible to find both DO-41 & SMD packages of the diode.
The diode has a current-reverse leakage property which significantly minimizes its leakage.
Moreover, it has a diffused junction and a 3W maximum power dissipation.
The diode best operates at a temperature range of -55 degrees – +175 degrees Celsius.
