| When in foward baised what will a Zener Diode act like? |
|
|
Term
If knee voltage is meet then will act as short.
If knee voltage is not meet then it will act as a open. |
|
Definition
| In reverse baised what will a Zener Diode act like? |
|
|
Term
| Avalanche breakdown will occur and reverse current flow through the diode. |
|
Definition
| What is it called when reverse biasing voltage becomes overwhelming and the depletion zone completely overtakes the two pieces of doped material? |
|
|
Term
|
Definition
| The most common use for a Zener Diode? |
|
|
Term
| The increase in load voltage willl decrease the forward base bias and raise the DC collector to emitter resistance of the transistor. This will increase the collector emitter voltage drop and prevent the load voltage from rising. |
|
