Diodes are widely utilized in circuit applications, primarily in the form of Standard diodes, Zener diodes and Schottky diodes. Zener diodes are commonly used in power supplies and other applications to maintain a fixed voltage in the circuit. Single Zener diodes, due to their wide range of power handling capability, are a popular choice for electronic applications. The PTV12B-M3/85A is one such example of a single Zener diode.

The PTV12B-M3/85A is an efficient and reliable single Zener diode designed for both linear and switching power supplies. Manufactured by Kroran, this diode is rated for a maximum power dissipation of 750mW, with a reverse voltage of 12V. It is capable of supporting a wide operating temperature range from -40°C to +150°C and has a peak reverse power dissipation of 1.5W. It has a rated forward voltage of 1.25V, a maximum reverse leakage current of 4.3uA, and an overall capacitance of 4.7pF.

This single Zener diode is extensively used in a wide variety of applications such as constant voltage circuits, protection circuits, and bias circuits, among others. In constant voltage circuits, this diode helps to maintain a preset voltage in the circuit, protecting the connected components from over voltage and surges. Similarly, it is used in protection circuits and bias circuits to maintain a constant voltage and avoid damage to the connected components. This versatile diode also finds application in a number of other circuits such as switching regulator circuits, voltage regulator circuits and reference circuits.

The PTV12B-M3/85A diode works on the principle of a Zener diode. A Zener diode is a device with a reverse voltage breakdown property. When a voltage is applied across the diode which is higher than the specified reverse breakdown voltage, the diode acts as a short circuit, allowing current to flow in the reverse direction. The breakdown voltage of the Zener diode is the voltage at which the diode switches to a low resistance mode, allowing current to flow in the reverse direction. In the case of the PTV12B-M3/85A, the breakdown voltage is 12V.

When using this diode in a circuit, it is important to ensure that the applied voltage does not exceed the maximum allowed reverse voltage or power dissipation for the device. Operating at higher voltages or power dissipation levels than what is specified could cause the diode to fail and lead to permanent damage. It is also important to select appropriately rated heat sinks for this diode to ensure proper thermal management.

The PTV12B-M3/85A is a versatile, reliable and efficient Zener diode which is used extensively in a variety of circuits, particularly in high power applications where a constant and reliable voltage level is required. It is a single Zener diode made by Kroran and is rated for a maximum reverse voltage of 12V. It is capable of handling a wide operating temperature range and has a peak reverse power dissipation of 1.5W. It is widely used in circuits such as constant voltage, protection, bias and switching regulator circuits, due to its high reliability and power handling capability.
