1N4733A Zener Diode The 1N4733A is a silicon planar power Zener Diode for use in stabilizing and clipping circuits with high power rating. It is designed for voltage stabilization. Features Nominal Zener Voltage (VZ): 5.1V Power dissipation (PZ): 1300mW (practically 500mW) Zener regulator current (IZm): 178mA Package: DO-41 How to select a Zener Diode A Zener diode is another form of diode but is used for entirely different purpose. They are mainly used in protection circuits or as crude voltage regulators. Let us see how we can select one for your application.There are two main parameters that are to be checked while selecting a Zener diode in a circuit. One is the Zener Voltage and the other is Power dissipation. The Zener voltage is the voltage which appears across the Zener diode when a higher reverse potential voltage is applied to it. In regulator circuits, it is this voltage (Zener voltage) which will be regulated and in protection circuit it is this voltage (Zener voltage) more than which the circuit is protected. The power dissipation decides the amount of current that can flow through the diode. Higher the power dissipation, higher the current can flow. Pin Description Anode : Current always Enters through Anode Cathode : Current always Exits through Cathode Applications of Zener Diodes Used in Voltage protection circuits Can be used as low current voltage regulator Input voltage protection for Microcontrollers or other IC’s Voltage stabilizing circuits Package Include 1x 1N4733A Zener Diode United Arab Emirates dirham - AED SKU: CA075 Categories: All Products, Diodes
