Method for temperature-compensating zener diodes having either positive or negative temperature coefficientsnot available for EP060000of corresponding document:An auto-TC voltage reference (Vo) wherein an operational amplifier (20) receives at one input (22) the voltage of a Zener diode (24) and ...
As shown the apnote says "A Zener diode is also used in this circuit to protect from pack transients similar to the FET circuits." For the FET the zener will limit both the positive and negative gate voltage. With the NPN shown the base-emitter voltage...
Diodes usually come in glass or plastic cylindrical packages, marked with a stripe on one side to indicate polarity. In a perfectly ideal diode, current flows in one direction only, from the anode (positive side) to the cathode (negative side) which is marked with the stripe. The schematic ...
When AC voltage is applied to the Zener diode then any voltage above Zener breakdown is clipped off. The two diodes connected in series with opposite directions cause clipping of AC in both positive and negative cycles. An example of a clipping circuit is a sine to square wave converter. Fig...
During the negative swing of the AC voltage however, the zener diode behaves just like the normal diode and clips the output voltage at 0.7V, Consistent with normal silicone diodes. To implement the clipping circuit for the negative swing of the AC circuit as well as the positive swing in ...
When any diode's p terminal is connected to the positive terminal of the power supply and n to negative, it is called as forward bias. When the applied voltage becomes greater than the barrier potential, (maybe 0.7V) the diode becomes a very good conductor. Opposite connection is known as...

稳压二极管（Zenerdiode）稳压二极管（Zener diode）Zener diode (also known as zener diode) is a silicon material surface contact type crystal diode, referred to as the regulator. This diode is a semiconductor device with a high resistance until the critical reverse breakdown voltage is applied. The ...
Zener diodes with a negative temperature coefficient exhibit a Zener volt- age reduction, whereas those with a positive temper- ature coefficient show a Zener voltage increase on application of current. The magnitude of this voltage change due to intrinsic heat generation can be derived from the ...
Thus in a 5.6 V zener diode both zener and avalanche effects are equally predominant thus its positive and negative temperature dependency cancels each other. Thus naturally 5.6 V zener diode is the component of choice in temperature critical applications. ...
