The main parameters of the diode

1, the maximum rectifier current IF: refers to the long-running tube, allowing maximum average forward current through. Because the current through the PN junction to cause the tube heat, too much current, the heat over the limit, it will make the PN junction burn. For example 2APl maximum rectifier current 16mA.

2, the reverse breakdown voltage VBR: refers to the reverse breakdown voltage of the tube. Breakdown, reverse current surge, the diode one-way conductivity is destroyed, even due to overheating and burn. General manual gives maximum reverse breakdown voltage of about half the voltage in order to ensure the safe operation of the tube. For example 2APl maximum reverse voltage is defined as 2OV, but in fact the reverse breakdown voltage greater than 40V.

3, reverse current IR: refers to the reverse current breakdown at the end of the tube, and its value is smaller, the better the way the conductive tube. Because of temperature increases, the reverse current increases dramatically, so pay attention when using the diode temperature.

4, electrode capacitance CJ: between diode capacitance include barrier capacitance and diffusion capacitance at high frequencies must consider the impact of using the junction capacitance. Diodes different working conditions, the impact of the effect between its capacitance also different.
