Cards

Term
what voltage advantages a full wave has over half wave?
Definition
Vp ,Ip , Pd is halved
Term
what difference in peak current for charging and discharging full wave and half wave?
Definition
  •  full wave has more time to charge and discharged.
  • therefore has less peak current vs half wave has twice more.

Term
if i wanted to regulate 10 V in a circuit , what should i do?
Definition

use zener diode

  •  use it in rev biase
  •  Vb as voltage regulation.
Term

Imax= (Vth/Rth) =2/(3/2) =4/3 A

Term

 

Explain how change schottky diode into ohmic conductor?

Definition
  • doping the material ,make it N type



  • bring down the hill to allow electron flow
Term

Name 3 advantage of schottky diode?

Definition
  • easy to make
  • has less noise
  • low turn on voltage
Term

breakdown region in electric field for

 

  • P-N diode
  • Zener diode
  • Schottky
Definition

when a negative voltage is applied on the p side , electric field (electron hill gets bigger). it will do so until cannot hold on any more voltage. heats up and breaks down.

 

  • zener-no breakdown-still work
  • schottky dont have p side - breakdown faster than p-n diode.
