TVS or known as Transient Voltage Suppressor (TVS) diodes are specially designed to protect electronics from voltage surges. Until recently, the most common protection components used for this purpose were gas tube arresters (also known as spark gaps). Despite some advantages, these components have numerous disadvantages. TVS diodes have been developed to replace gas tube arresters, and the JANTX1N6112AUS is an example of such a device in the family of TVS diodes.

JANTX1N6112AUS, a current-feedback (CF-TVS) component, is designed to protect sensitive products from overvoltage transient events. It is specially designedfor sensitive circuits in automotive applications, such as those found in antilock braking systems, airbag deployment systems, and occupant restraint systems. This component is rated with 6V nominal working voltage and 12A super fast power clamping current. Its ultra-fast response at only 8V transient voltage makes it an attractive device for protecting automotive circuits both in fault situations and also for EMI/RFI noise immunity.

From the physical point of view, the JANTX1N6112AUS consists of two pins, with the anode connected to the anode pin and the cathode connected to the cathode pin. Internally, the two pins are connected to a reverse biased pn-junction which is in series with an avalanche region. When a certain voltage level is reached, which is defined by the clamping voltage of the component, the pn-junction is breached and a current which is limited to the clamping current of the component is fed to the circuit.

The response of the JANTX1N6112AUS is highly dependent on its physical environment. It is recommended that the component is placed close to the protected circuit. Moreover, the least amount of trace lengths on the PCB should be used to connect the two pins of the component to the circuit. The leads should also be properly soldered and be kept as short as possible.

It is important to understand that the JANTX1N6112AUS, as with any other TVS diode, is not a substitute for short circuit protection as it is not designed to withstand a continuous overload current. The JANTX1N6112AUS is designed in such a way that the likelihood of circuit damage due to an overvoltage transient event is minimized.

In conclusion, JANTX1N6112AUS is a type of TVS diode which is specially designed to protect automotive circuits from transient overvoltage events due to its fast response time and high clamping voltage. It is an attractive device for protecting automotive circuits from both faults and EMI/RFI noise immunity. In order to get the most out of this component, it is recommended it be placed near the protected circuit, leads should be kept short and the connection should be properly soldered. The JANTX1N6112AUS does not constitute a means of short circuit protection however, and other electronics protective components should be employed for that purpose.
