Zener diode, should pay attention to matters

The Zener diode versatile. Looks very simple, but if you do not pay attention, but also easily damaged.

Only Zener diodes in series may be used, but due to the discrete nature of the diode parameters are relatively large, can not be used in parallel.

Temperature a greater impact on the characteristics of semiconductor devices, when the ambient temperature exceeds 50 ° C, the temperature is increased by 1 ℃, the maximum power dissipation should be reduced by 1%.

Zener diode pin must be in at more than 5mm away from the shell and tube welding, it is best to use a soldering iron 30W less power. 40 ~ 75W soldering iron welding, soldering time should not exceed 8 ~ 10s.Try to use the built-in solder, solder wire welding, do not use a large piece of tin.

Zener diode voltage temperature coefficient compensation Zener diode silicon diode (including silicon zener diodes) can be used in tandem, the forward diode string of not more than three, with a special temperature compensation tube in series to use.

In order to obtain lower stable voltage, can select the appropriate Zener diode connected in series in the opposite polarity direction, coupled with the proper working current. Upcoming regulator diode forward.
