Different types of diodes have different parameters.We must understand the following main parameters:

4. Reverse Current
Diode reverse current is at a temperature and a predetermined maximum reverse voltage is applied, current flows through the diode reverse. The smaller the reverse current, the conductive performance of the tube in one direction, the better. It is noteworthy that the reverse current and temperature are closely related, the temperature is increased by about 1 0 ℃, the reverse current increases doubled. For example 2APl type germanium diode, at 25 ℃, the reverse current of 250μA, the temperature rises to 35 ℃, reverse current will rise to 500μA, at 75 ℃, its reverse current has reached 8mA, not only lost a single direction of the conductive characteristics, the tubes will overheat and damage. Than the germanium diode silicon diode has good stability at high temperatures.

5. Reverse Recovery Time
From the forward voltage becomes a reverse voltage, ideally instantaneous cut-off current can, in fact, there are generally a little time delay. Determine the amount of current cut-off delay, that is the reverse recovery time. Although it directly affects the switching speed of the diode, but not necessarily say that this value is small enough.

6. Maximum Power
Maximum power is applied across the diode voltage multiplied by the current flowing. This limit is especially important parameter for regulator diodes.

Different types of diodes have different parameters.We must understand the following main parameters:

1. Rated Forward Current
Rated forward current diode means T for long-term continuous permissible maximum forward current through. Because the current through the heating tubes will die, the temperature rises, the temperature exceeds the allowable limit (silicon tube of about 1 40 ℃, germanium tube is about 90 ℃), the die will cause overheating and damage. Therefore, do not use more than diode forward current diode rated value. For example, the commonly used lN400l type germanium diode forward current rating of  lA.

2. Maximum Surge Current
The maximum inrush current is allowed to flow through the excess forward current. It is not a normal current, but the current moment, this value is typically about 20 times the rated forward operating current.

3. Maximum Reverse Voltage
Applied reverse voltage across the diode high music to a certain value, the tube will breakdown, loss of unidirectional conductivity. To ensure safely use, it provides maximum reverse voltage. 
For example, lN400l diode reverse voltage reverse voltage 50V, lN4007 for l000V.
