Refer to the zener diode datasheet in Figure 3–7.

(a) What is the maximum dc power dissipation at 25°C for a 1N4738A?

(b) Determine the maximum power dissipation at 70°C and 100°C for a 1N4751A.

(c) What is the minimum current required by the 1N4738A for regulation?

(d) What is the maximum current for the 1N4750A at 25°C?

(e) The current through a 1N4740A changes from 25 mA to 0.25 mA. How much does the zener impedance change?

(Reference Figure 3-7)
