TVS, or Transient Voltage Suppressors, are diodes that provide protection against destructive over-voltage transients. The P4KE160CA, in particular, is a unidirectional diode TVS that is designed to protect into-the-cable connections from transients. It is often used in automotive applications, such as for Electronic Control Units (ECU) or airbag circuits.

The P4KE160CA is constructed from multiple stacked avalanche diodes with extremley low reverse and forward leakage currents. Its ultra-fast response time helps reduce false tripping and extends its service lifetime. It is rated for a peak power of 400W and an operating voltage range of 4.5V to 160V. The P4KE160CA is also RoHS compliant, meaning it does not contain any hazardous materials.

The P4KE160CA works by presenting an extremely high resistance when a transient is encountered. The avalanche diodes will switch into their breakdown region, dissipating any energy from the transient without destroying the TVS. All this happens in a micro-second, protecting whatever is being supplied from the transient voltage.

The P4KE160CA provides robust protection for a variety of applications. Its low capacitance makes it especially useful in applications needing high-speed data transmission, such as Ethernet or CAN networks in automotive electronics. It can also be used to protect a variety of small electronics, such as phones, tablets, or laptops. The P4KE160CA is also used to protect solar panels from surges due to lightning strikes, helping ensure long-term performance and safety.

In summary, the P4KE160CA is a unidirectional TVS diode that provides reliable protection against destructive over-voltage transients. It can withstand a peak power of 400W and has an operating voltage range of 4.5V to 160V. Common applications include automotive systems, Ethernet/CAN networks, and solar cells. The P4KE160CA is constructed from multiple avalanche diodes that switch into their breakdown region when a transient is encountered, dissipating the energy and protecting the application.
