Question

Table 1: Zener Diode Parameters Description Quantity Value 1.0 W Po Absolute maximum power dissipation Typical zener voltage 5.6 V Minimum zener (knee) current 1.0 mA 45 mA Typical zener current Maximum zener current IZM Zz Zener impedance Zener knee impedance 179 mA 52 600 22 25 °C ZzK ΤΑ Rated ambient temperature 1N4004 Rs = 100 22 220 uF 1N4734A Transformer Vs = 12.6 VRMS 1N4004 60 Hz

Answer 1

AR Gotty If in a rectifier cet, output is DC4 1260 I won 12.604 Tatu Case-I, when R oo (0) open ckt or Re is removed ar Vz usd I luar I 12.6.. o al Total ekt Current Ir a Vy - Vz Rs 12-6-5.6 100 RS 8R²7.0.07 70 mA 6) Load Current, 2 , zo (open (kat) () Zener Current, Iz = IR = 70mA. It is safe since given the Mare ineum zener Current in 179 mA. Vs le vzco Case of one of a) Total Current (Cht) = AR = Vs - 12 - 12-6-0 12.6 1oo Tvo 2126MA b) Load Current, = I ₂ = 122 126ma c) Zener Current, Izzo (since load is shorted)
