PZU16B1A,115

A Zener diode is a special type of diode that has a reverse breakdown voltage that is predetermined. Specifically, it has a terminal voltage – across the diode – that “clamps” at the predetermined breakdown voltage when it is reverse-biased. This feature allows the diode to regulate a specified voltage as it passes a forward current.

The PZU16B1A,115 is a single Zener diode that is commonly used in applications requiring the Zener voltage to be regulated accurately and precisely. This diode has a Zener voltage range of 17.8 to 18.1V, with an absolute maximum of 18.2V and a minimum of 17.7V. It is capable of conducting an average forward current of 140mA, with a peak forward current of 600mA, and can also handle a 100µA maximum reverse leaking current.

The core of the PZU16B1A,115 is composed of an N-type semiconductor substrate along with a heavily doped p-type layer. Given that a diode is a junction between the two layers, this arrangement of materials and the dopant densities allows for a large voltage drop that regulates the current in the opposite direction. This feature is utilized for reverse current protection, and would be especially helpful in powering high power equipment, or protecting circuits from fluctuations in input voltage or over-voltage conditions.

The Zener diode works through a process known as reverse breakdown or “avalanche breakdown”, which occurs when the reverse bias on the diode reaches a certain point. This is often due to a decrease in the external resistance, or a reduction in the reverse bias of the diode itself. As the current reaches the breakdown voltage, it is passed through the diode at a limited rate. This is due to the high electric field created between the depletion region and the p-type layer, which causes electrons to gain energy as they move through the junction. This allows electrons to be swept across and reaches a negative value faster than under normal operating conditions, thus creating the “clamping” effect.

The clamping is beneficial in applications where a specific voltage level needs to be maintained to ensure the correct operation and performance of the device. It is used extensively in a wide variety of industries, from the telecommunications and electronics markets to power supplies, surge protection and even automotive applications. Combined with the PZU16B1A,115’s ability to handle a high forward current and low reverse current, this makes it well suited for these types of applications as it is highly durable and reliable.

In conclusion, the PZU16B1A,115 is a single Zener diode that is designed for use in applications where a predetermined reverse breakdown voltage is necessary. It is composed of an N-type substrate and a heavily doped p-type layer, and is rated to a Zener voltage range of 17.7V to 18.2V. It is capable of conducting a peak forward current of 600mA and can handle a maximum reverse current of 100 µA. This makes it ideal for use in surge protection, power supply regulation and automotive applications in which the diode needs to handle a wide range of voltages and currents.
