The SMBJ16A-HRA is a transient voltage suppressor diode (TVS-Diode), which is used to protect sensitive components and circuits from overvoltage transients caused by various external sources like electromagnetic fields, mechanical stress, electrostatic discharge, inductive loads, lightning loads, and any other power surge.

The SMBJ16A-HRA is designed with a special structure, which consists of two dissimilar metal-oxide layers and an additional dielectric-insulating layer. This structure allows the diode to have a very low capacitance, provide a high surge rating, reduce capacitive current, and have excellent clamping capability. Additionally, the dielectric-insulating layer prevents any type of electrical leakage that would occur due to current passing between the two layers.

The SMBJ16A-HRA offers high-speed response to voltage surges, providing a high level of protection from damaging overvoltage transients. Its low junction capacitance and low operating voltage make it suitable for a wide range of applications, such as in automotive systems, telecommunications systems, lighting systems, computers, and medical equipment. Additionally, the SMBJ16A-HRA can operate at high voltages up to 16 V, and can withstand a large surge current of up to 1500 A.

The working principle of the SMBJ16A-HRA is based on the principle of avalanche breakdown. When a surge voltage greater than the device\'s breakdown voltage (BDV) is applied, a large avalanche current passes through the diode. This avalanche current is high enough to cause current flow in the reverse direction, which will ultimately cause the diode to turn OFF and provide protection to the device. Additionally, the diode can quickly return the current and voltage to its normal level when the surge subsides.

The SMBJ16A-HRA can be used in a variety of applications, including protection for sensitive electronic components such as resistors, capacitors, integrated circuits, and motors. It can also be used in power supplies, voltage regulators, and high-frequency circuits. Additionally, it can be used to protect systems from power surges caused by lightning strikes.

In conclusion, the SMBJ16A-HRA offers an effective solution for overvoltage protection. Its low junction capacitance and high surge rating make it ideal for a wide range of applications, from automotive systems to medical equipment. It is also designed to offer a high level of protection from damage due to external power surges, such as those caused by lightning. With its fast response time and low operating voltage, the SMBJ16A-HRA is an ideal choice for protection from overvoltage transients.
