Semiconductor Electronics · p-n junction and diodes
The following diagram shows a Zener diode as a voltage regulator. The Zener diode is rated at V and the desired current in load is 5 mA. The unregulated voltage source can supply upto 25V. Considering the Zener diode can withstand four times of the load current, the value of resistor (shown in circuit) should be .
