The main electrical characteristics specified in the diode datasheet are forward voltage, reverse current, terminal capacitance, reverse recovery time, etc.
This section describes each of the electrical characteristics specified in diode datasheets. Different electrical characteristics may be specified for different types of diodes. Electrical characteristics are specified at an ambient temperature (Ta) of 25°C unless otherwise noted.
An example of an electrical characteristic item in a diode technical datasheet is shown below.
Characteristic | Symbol | Test Condition | Min | Typ. | Max | Unit |
---|---|---|---|---|---|---|
Forward voltage | VF (1) | IF = 1 mA | — | 0.61 | — | V |
VF (2) | IF = 10 mA | — | 0.74 | — | ||
VF (3) | IF = 100 mA | — | 0.92 | 1.20 | ||
Reverse current | IR (1) | VR = 30 V | — | — | 0.1 | µA |
IR (2) | VR = 80 V | — | — | 0.5 | ||
Total capacitance | CT | VR = 0 V, f = 1 MHz | — | 2.2 | 4.0 | pF |
Reverse recovery time | trr | IF = 10 mA (Fig. 1) | — | 1.6 | 4.0 | ns |
In addition, some diodes have individual maximum ratings. See the application note below for details.
