SZBZX84C12LT1G

SZBZX84C12LT1G is a Zener single diode designed for use in applications requiring medium power, moderate to low temperature coefficient, and low peak reverse power dissipation. It has a high voltage rating of up to 84 volts. SZBZX84C12LT1G is available in a variety of packages, including the popular SOT-23 package.

Application Field

Zener diodes are widely used in a variety of applications, such as voltage regulation, clamping, and transient protection. They are commonly used in linear regulators, power supplies, inverters, and many other devices that require voltage regulation or current limiting.

SZBZX84C12LT1G is commonly used in automotive and mobile applications. Its low stand-off voltage, low maximum reverse current and low dynamic capacitance is ideal for circuit protection in these applications. It is also used in discrete DC-DC converters, line filters, oscillators, and as an input protection device in power systems.

Working Principle

When a Zener diode is reverse-biased, a voltage-dependent phenomenon known as ‘Zener Breakdown’ occurs in the diode junction. At a specific reverse-bias voltage, electrons are accelerated by an electric field in the junction to form a narrow depletion region, producing a conductive path, resulting in current flow from anode to cathode.

The SZBZX84C12LT1G Zener diode has a specific voltage breakdown voltage. This voltage is referred to as the Zener Voltage, or characteristic voltage. Once the Zener Voltage is reached, current begins flowing from the anode to cathode and the voltage drop across the diode is held constant, at the characteristic voltage. This ability to maintain a constant voltage drop allows for regulation of an input or output voltage.

SZBZX84C12LT1G Zener diodes also have a nominal power rating, which is the maximum amount of power the diode can dissipate without damage. This is an important factor to keep in mind when selecting a diode, as exceeding the power rating can result in catastrophic failure.

Conclusion

SZBZX84C12LT1G is a Zener single diode that is used in automotive and mobile applications that require low stand-off voltage, low maximum reverse current, and low dynamic capacitance. Its characteristics include a high voltage rating of up to 84 volts and a nominal power rating of 1 watt. It also operates according to Zener Breakdown, where electrons are accelerated by an electric field to create a conductive path from anode to cathode. This allows for a constant voltage drop across the diode, enabling voltage regulation.
