1N4782

A 1N4782 is a type of single Zener diode which can be used for a variety of applications.

The 1N4782 Zener diode has a wide range of power levels; it is rated at 1W and can withstand voltages up to 50V. It is built from a single element of heavily doped n-type semiconductor, usually germanium. The n-type semiconductor has a larger bandgap than the p-type material, so it can break down more easily at higher voltages.

A Zener diode works in the reverse direction. When positive voltage is applied to the anode, the diode will break down, allowing large amounts of reverse current to flow from the cathode to the anode. This reverse current will increase as the applied voltage continues to increase.

The 1N4782 Zener diode can be used as a voltage regulator, as it maintains a constant voltage output as the input voltage fluctuates. It is commonly used in power supply designs, video equipment, medical monitoring and diagnostic instruments, and avionics.

The 1N4782 Zener diode is also used as a protection device due to its ability to limit the voltage going through a circuit. In cases where a reverse voltage is applied to the anode, the diode will prevent the voltage from exceeding its rated maximum.

The 1N4782 can also be used for switching, as it can be turned on and off quickly. It is commonly used as a switch in electronic circuits, as it can withstand up to one watt of power.

In addition to these common applications, the 1N4782 Zener diode can be used for other purposes such as pulse shaping, RF signal filtering and transient suppression. It is also used in precision circuits to provide a steady, low-noise reference voltage.
