Dioden Kennlinie linear in LTSPICE
Quelle: Vollrath
Beispiel: Diodenspannung
Berechnen Sie die Diodenspannung für eine Siliziumdiode mit Is=0.1fA,
wenn bei Raumtemperatur ein Strom von 300 \mu A fließt?
Wie groß ist die Diodenspannung für Is=10fA?
Wie groß ist die Diodenspannung bei einem Strom von 1mA?
VT = 25mV, n = 1
td Stromspitze Einschalten, ts konstanter Gegenstrom, tf Abfall des Gegenstroms
Schaltverhalten: Messung
Mittlere Diode aus dem Diodenversuch.
Kleinster Widerstand 100 Ω am Ende des Sockels.
C1 zeigt das Rechteckeingansgsignal zwischen +8 V und -2 V mit einer Frequenz von 500kHz.
C2 zeigt die Diodenspannung.
Ohne eine Speicherladung im pn Übergang, sollte der Strom (M1) durch die Diode bei Sperrspannung
sofort Null werden.
Da gespeicherte Ladung vorhanden ist, sieht man noch einen Stromfluss.
Dieses Verhalten entspricht einem Kapazitätsverhalten, man spricht von der Diffusionskapazität.
