TVS diode or Transient Voltage Suppresor (TVS) are used to protect the circuit from potentially damaging voltage transients produced by lighting strikes, power sources and electrostatic discharge. The P4KE200C is a unidirectional or bidirectional TVS diode specifically designed for applications such as signal lines, power lines, and telecommunications.

The P4KE200C is designed to protect against transients up to 200 volts peak, and it is able to dissipate power greater than 16 watts in unidirectional version or 10 watts in case of bidirectional version. All parts are UL recognized, CSA certified, and meet or exceed the following surge performance, IEC 61000-4-5 (2nd edition): 8/20 us standard wave (level 4) 2,000 Amps (8/20 us).

This P4KE200C is packaged in surface mount (SMD) Plastic case with a minimum lead spacing of 0.5mm. It is a very compact and highly reliable solution for transient protection applications. It is designed to provide excellent protection from low energy transients and high energy surges, as well as easy integration into higher current protection schemes. This device also offers excellent ESD protection for communication lines.

The P4KE200C Transient Voltage Suppressor is built with a diode bridge in two different designs: unidirectional, and bidirectional. The breakdown voltage is usually in the range of 5 to 200 volts. The P4KE200C has a specified breakdown rating of 177V.

The unidirectional (or ‘crowbar’) version of the P4KE200C is designed to protect two separate lines from over voltage or ESD. This provides protection from both positive and negative transients on either side of the protected line as long as the transient energy is less than the maximum power rating of the device. The unidirectional version of the device will cause the voltage on the line to drop to approximately zero volts during a surge event.

The bidirectional version of the P4KE200C protects two lines from over voltage or ESD on either side of the device. This protects against both positive and negative voltage transients. The bidirectional version will cause the voltage on the line to drop and then rise again to a level close to the original voltage. This helps reduce the risk of circuit damage due to overvoltage.

The P4KE200C device has a low capacitance between the lines and high surge capability for excellent ESD protection of signal lines and other sensitive components. It offers good thermal characteristics and good electrical performance with minimal propagation delay. This device is designed for high reliability and long-term stability, and it comes in a small size package for increased flexibility in design.

The P4KE200C is an ideal choice for protecting sensitive electronic components against voltage transients and power surges. Its low capacitance, high surge capability, and robust construction make it suitable for a wide range of applications, such as signal lines, power lines, and telecommunications.
