Diodes - Zener - Single

1N5253C-TR is a single zener diode designed for protecting voltage sensitive components in a circuit from transient over-voltage. It is also used for stabilizing and providing regulation at shallow level and helps in dissipating heat. It has a wide operating temperature range and provides noise suppression when used as a Zener diode.

Application Field of 1N5253C-TR

1N5253C-TR operates in the reverse breakdown region and acts as a voltage regulator and a voltage clamper. It is ideal for use in applications like electronic circuits, automotive, microwave and laser systems, industrial, robotics and digital systems. It can protect circuit devices from transients by clamping voltages that exceed a certain voltage. It can also be used to provide positive or negative voltage regulation and ripple reduction.

As a component in the electronic circuits, this diode is used in a variety of circuits. It is used in Zener voltage regulation circuits, voltage multiplication circuits, TV and radio receivers, computers and other digital equipment, power supplies and high power rectification, surge suppression and protection of voltage sensitive components.

Some of the applications this diode can be used for include medical equipment, X-ray equipment, transistors, high-frequency transducers and oscillators, current limited power supplies, precision voltage references and voltage regulators, switched-mode power supplies, and surge suppression.

Working Principle of 1N5253C-TR

When the current in the 1N5253C-TR exceeds a certain threshold value, the voltage at the junction increases exponentially. This phenomenon is called Zener breakdown or Zener effect. The Zener breakdown occurs when the electric field within the small area of the junction reaches a critical point and the electrons have sufficient energy to break the bonds within the lattice and allow the current to flow in the reverse direction.

When the diode is connected in a circuit, a stable DC voltage is applied to the diode which causes current to flow through it. This current is regulated by the forward voltage drop of the diode, which determines how much voltage will be present at the junction. If higher voltage is applied to the diode, it will conduct more current. This regulation of voltage and current is called the Zener effect.

When the current reaches its peak value, the inverse voltage at the junction will be around 0.7V. If the applied voltage exceeds 0.7 volts, the diode will be in the breakdown region and the current will start to increase exponentially. The voltage is thus limited to the breakdown voltage which is specified in the datasheets of the diode.

This Zener diode can be used to provide positive or negative voltage regulation, as well as to provide noise suppression in circuits. It can be used in applications such as surge suppression, TV receivers, digital equipment and power supplies. The operating temperature range is from -55°C to +160°C.
