Diodes - Zener - Single

The BZX85B16-TR is a single zener diode which is used in various applications. A zener diode is a type of semiconductor device with a reverse breakdown voltage that is greater than the forward-bias saturation voltage. These diodes are commonly used for regulating voltages in electronic circuits, and the BZX85B16-TR is a particularly reliable and efficient device for that purpose.

Application Field

The BZX85B16-TR can be found in many different applications, particularly those where regulating or stabilizing a voltage is required. These include power supplies and control circuits. It is also used in audio and video equipment, including speakers, amplifiers, and televisions.

Furthermore, this device is often used to protect circuits from electrical or static overstresses, and it can be connected between the power line and the primary stage of a power supply to disconnect the circuit in case of overvoltages. Additionally, the BZX85B16-TR is often used in radio frequency amplifiers and thermistor circuits.

Working Principle

The zener principle works by utilizing the property of certain semiconductor diodes. When these diodes are connected with the reverse voltage applied, an abrupt increase in current known as ‘avalanche breakdown’ occurs. Zener diodes are specifically designed to maximize this effect. Due to the low impedance of zener diodes in its breakdown region, it provides a stable output voltage for the rest of the circuit it is connected to.

In the case of the BZX85B16-TR, its operation is based primarily on the principle of avalanche breakdown. It has an ICBO breakdown voltage of 16V, which means that when the voltage across its terminals exceeds 16V, it starts conducting. Current passing through the device is dissipated as heat, and this prevents the forward voltage from rising any further.

In summary, the BZX85B16-TR single zener diode is an efficient and reliable device which is used in a variety of applications. It utilizes the principle of avalanche breakdown to regulate the voltage in an electrical circuit and protect it from overvoltages and static stresses. Thus, it serves as an important component of numerous electronic devices and systems.
