Transient Voltage Suppressors (TVS) are a type of device used in electronic circuits to protect them from damage due to high voltage transients. The MXLRT100KP78CA, often seen as the K78CA, is an axial leaded TVS diode specifically designed for transient current and over-voltage protection. This diode is most often used in automotive and industrial applications such as computers, instrumentation, communications, and consumer electronics for protection from surges, power outages, and ESD (Electrostatic Discharge).

The MXLRT100KP78CA is comprised of an N-Channel MOSFET and an integrated diode. It is available in packages ranging in size from the leadless MLP-16 to the widely used SMA-3 smt package. This device features a breakdown voltage of 100V, a power dissipation of 200mW, and a response time of 200ps, which is ideal for these type of applications.

The K78CA works by acting as a voltage clamp, limiting the voltage on the line that it’s connected to. When the line voltage rises above the rated breakdown voltage for the diode, the diode will begin to conducting current. This current will flow out of the diode and be dissipated as heat. The diode will then remain in the conducting state until the line voltage drops below the breakdown voltage, at which point the diode will stop conducting.

The device also features an ESD protection circuit, which clamps the voltage to prevent ESD from causing malfunction or damage to the connected components. This circuit works by connecting the ground of the diode to the line that is being protected, thus providing an easy path for the current to flow. The diodes response time to this type of events is also impressively fast, being able to react to ESD events in under 8ns.

The MXLRT100KP78CA is a great choice for protecting delicate electronics from surges, power outages, and ESD. With a wide range of packages, a fast 200ps response time, and integrated ESD protection, it is the perfect choice for automotive and industrial applications.
