Diodes - Zener - Single

The SMAJ5922E3/TR13 zener diode is a two-pin surface mount component that is used for a wide range of applications. This type of diode is ideal for many different applications including voltage regulation, power supply design, circuit protection, and as a crowbar device. It has a low-profile package and a wide range of working voltages.The SMAJ5922E3/TR13 is a type of three-terminal voltage regulator diode. It is used to regulate the output of a DC power supply. The diode is made of an oxide-layered semiconductor material which has a distinct breakdown voltage. This breakdown voltage is established when an electric current passes through the junction which causes the material to become conducting. The reverse breakdown voltage is the key to regulating the output of the power supply.

Working Principle

The SMAJ5922E3/TR13 works on the principle of avalanche breakdown. This occurs when the forward-biased voltage of the diode exceeds the threshold and an avalanche of electrons is created in the junction, resulting in an abrupt increase in current. The voltage at which this happens is the breakdown voltage, which is the reverse voltage at which the diode begins to conduct. The breakdown voltage of the SMAJ5922E3/TR13 is 8.2 V, which is perfect for regulating the output of a DC power supply.When the input voltage of a DC power supply exceeds the breakdown voltage of the diode, the diode begins to conduct, allowing current to flow in the reverse direction. This current then dissipates as heat and the output voltage of the power supply is regulated.The SMAJ5922E3/TR13 is capable of dissipating up to 500 mW of energy. This allows it to handle a wide range of power supply outputs that exceed the breakdown voltage. It is also able to operate over a temperature range of -55°C to +155°C.

Applications

The SMAJ5922E3/TR13 is widely used for voltage regulation and power supply design applications. It is ideal for use in switch mode power supplies as it is able to operate over a wide range of input voltages. It is also suitable for use in DC-DC converters and in traditional linear regulated power supplies.The SMAJ5922E3/TR13 is also used for circuit protection purposes. It can be used as a crowbar device to disconnect circuits in the event of an overload or short circuit. It can also be used in AC line filters to reduce harmonic distortion by clamping high voltage spikes.In addition, the SMAJ5922E3/TR13 is used in surge suppressors, defibrillators, and other medical systems. It can also be used in automotive and consumer electronics applications.Overall, the SMAJ5922E3/TR13 is an ideal component for many applications where voltage regulation and circuit protection are required. With its low-profile package and wide range of working voltages, it provides reliable and stable performance for a variety of systems.
