TVS – diodes, or Transient Voltage Suppressors, are electrical components that regulate voltage, protect circuits from over-voltage conditions, and suppress noise in power supplies. The P4KE170CA-E3/73 is a high-performance TVS diode designed to protect high-speed communications such as Gigabit and 10G Ethernet applications. It is suitable for ESD and other surge electrical transients. The P4KE170CA-E3/73 is versatile and reliable, preventing damage to the system from transients.

The P4KE170CA-E3/73 TVS diode has a low capacitance of 0.6pF and an operating voltage of 170V (AC peak). It is capable of absorbing the ESD Voltage up to 25kV (contact discharge) and up to 30kV (air discharge) with a maximum breakdown voltage of 170V. It has a low clamping voltage (Vc)of 21V maximum and an operating temperature range of -55°C to +125°C & +150°C for Industrial grade types.

The P4KE170CA-E3/73 is also suitable for protecting high-powered automotive electronics from electrical transients. It has an integrated \'VTMOS\' component for higher clamping voltage performance to protect systems up to 65V. The minimum continuous reverse voltage of the P4KE170CA-E3/73 is 85V, allowing it to be used in different applications.

The work principle of the P4KE170CA-E3/73 is based around its semiconductor layer. During normal full-load operation, current is conducted in the forward direction along the device. During over-voltage conditions, the current is clamped at voltage levels due to the avalanche breakdown characteristics of the P4KE170CA-E3/73. The TVS diode acts as a unidirectional current device that limits the current flow, thus not only ensuring the endurance of the equipment under over-voltage conditions but also protecting the equipment against short-circuits.

The P4KE170CA-E3/73 is unique thanks to its versatile characteristics. It can be used in many applications, from high-speed communications to automotive electronics. It is reliable and can be trusted to protect circuits from over-voltage conditions. It has a low clamping voltage and can absorb up to 25kV ESD voltage. The P4KE170CA-E3/73 is the perfect component for providing high-performance over-voltage protection.
