TVS-Diodes are electronic components used to reduce voltage fluctuations. SMAJ85A is a breakdown voltage of 14V unidirectional Transient Voltage Suppression Diode (TVS) developed by Unisonic Technologies. This device is typically used for suppressing the voltage transients caused by load switching, lighting, or ESD, and protecting vulnerable equipment. To be more precise, it provides a degree of protection for circuits against voltage spikes, which, if left unchecked, could damage or prevent proper operation of circuit.

The SMAJ85A device is metal oxide semiconductor field-effect transistors (MOSFETs) with a diode structure. The MOSFET structure includes three terminals, gate, source and drain, with the diode structure having two, negative and positive. The component acts as switch that can be turned on at a specified voltage threshold, during which electric current flows from the negative to the positive terminal. This voltage threshold is the breakdown voltage of the component, 14V in the case of the SMAJ85A TVS. Above this voltage, the diode is broken down, and a large surge of current passes through. The SMAJ85A also has a special design to allow for more resistance at low voltages and less resistance at high voltage. This means that, in an ideal application, the SMAJ85A can protect against large surges of current without interfering with normal operation.

The SMAJ85A also has a number of other features. For instance, the SMAJ85A has a high clamping voltage, which means it can handle high voltage levels without breaking down. This is particularly useful for applications with high voltage levels, as it can help protect against voltage spikes and other transient events. The SMAJ85A also has a low forward voltage, which ensures that it can support a low amount of current without excessive power loss. In addition, the TVS has a low reverse leakage current, meaning it is more resistant to current leakage. This reduces the risk of damage from electrostatic discharge (ESD) events, which can occur in electrically charged environments such as in manufacturing.

In terms of application, the SMAJ85A is typically used in computer and consumer electronic equipment. It is typically used in power supplies, motherboards and digital logic chips, where it can protect against voltage transients from load switching, lightning, or ESD events. The SMAJ85A can also be used in automobiles, where it can protect against voltage surges and transients during operation or starting. In addition, it is often used in industrial settings, where it helps to protect electrical systems from overvoltage and other transients.

The SMAJ85A is a reliable and efficient TVS, and can offer many benefits to its users. Its low breakdown voltage, high clamping voltage, and low forward voltage make it a good choice for many applications, including power supplies, consumer electronics, and automobiles. Its low reverse leakage current also makes it ideal for protecting circuits from ESD events. The SMAJ85A is a reliable, efficient, and cost-effective way of protecting circuits from voltage transients and other damaging voltages.
