The 15KP90CA, part of the 15KP series of TVS diodes, is an effective solution for protecting digital and analog circuits from damaging voltage transients that can occur on power supplies and signal lines. It has a high peak surge current capability and low capacitance, making it ideal for high speed data line applications.

The 15KP90CA is typically available in SMD versions with a standard Lead (Pb) free AEC-Q101 compliant package. It features a Repetitive Peak Pulse Power rating of 1.2 kW and a Peak Pulse Current rating of 90 A. It is available in multiple versions including a surface mount version.

The 15KP90CA is designed to protect circuits from momentary high voltage transients from lightning or other electrostatic discharges. It is rated for a working voltage range up to 30 Volts and can safely absorb pulses up to 90 Amps in peak surge current. It also offers a low capacitance range of less than 9 pF, making it suitable for data lines and fast rise time applications.

The working principle of the 15KP90CA is based on its silicon avalanche capability. When a transient voltage is applied to the diode, the positive temperature coefficient (PTC) of the diode will trigger an avalanche breakdown, allowing a current to flow. This current will surge for a short duration, providing protection to the circuit connected to it.

The 15KP90CA TVS diode is commonly used in automotive, industrial, communication, and consumer applications. It is primarily used for overvoltage/electrostatic discharge (ESD) protection of high speed data lines, as well as for EMI/RFI interference rejection. It is also used in circuit protection applications such as power supply line transient protection, power supply sequencing, reverse battery protection, and transient voltage line bypass protection.

In summary, the 15KP90CA TVS diode is a versatile and reliable solution for protecting digital and analog circuits from damaging voltage transients. It has a high peak surge current capability and a low capacitance range, making it ideal for high speed data line applications. It is available in multiple versions including a surface mount version, making it suitable for a wide range of applications.
