Transient Voltage Suppressor (TVS) Diodes provide a bidirectional protection across any voltage sensitive device. They offer a low-cost, easy to use, alternative to protection devices such as varistors and solid-state relays. TVS diodes are designed to resist high voltages and to limit the current pulses generated in the case of over-voltage or over-current conditions. The most common type of TVS diode is the P4KE27CHE3/54.

The P4KE27CHE3/54 diode is a bidirectional unidirectional peak pulse power surge suppressor. It features a working voltage range of 6.5 to 27V and a clamping voltage of 42V. It is designed for operation at ambient temperatures up to 150°C and is RoHS-compliant. The power pulse rating is 1.5KW to 15KW. It has a low capacitance of 5pF at 5V bias voltage and a fast response time of 5ns.

The P4KE27CHE3/54 can be used to protect against power transients in a variety of applications. It is well suited for use in LED driver circuits, automotive electronics, digital power supply and industrial power systems. It can also be used in high voltage power applications to provide protection from over-voltage, over-current, and undershoot conditions.

The P4KE27CHE3/54 diode operates by providing a high resistance path for any transient voltage or transient current that exceeds the working voltage or current limit of the diode. When a power transient occurs, the diode will quickly switch from a high resistance OFF state to a low resistance ON state, thus limiting or clamping the voltage or current. As the transient passes, the diode will switch back to the OFF state, providing a short, low impedance path. This will quickly dissipate any remaining over-voltage or over-current and restore the normal operating conditions.

The P4KE27CHE3/54 is a reliable, cost-effective alternative to other protection devices. With its high surge capability, fast response time, and low capacitance, it is well suited to a variety of applications. Its RoHS-compliant design ensures that it meets the most stringent environmental and safety requirements.
