Zener Diode / LED


  • (Zener Diode)

    2 P (A) N (K) (Zener Breakdown)



(Zener Voltage) Vz

(Equivalent Circuit)


  • (Zener Diode Characteristic Graph) (Vz)


  • 1. (VZ)

    2. (IZM)


  • Rx1 Rx10


  • (A ) (K )


  • Rx1 Rx10 0


  • 10 100


  • = x

    Pz = Vz x Iz

    Iz= Pz / Vz

    Pz(max)

    Iz(max) = Pz(max) / Vz
