The P4KE540-B TVS Diode is a bi-directional unidirectional surge suppressor diode designed to protect sensitive electronics from voltage transients in electrical and electronic systems, such as transients caused by lighting. It is part of IXYS-ChipExpress Corporation’s family of proven, high-performance transient voltage surge suppressors for consumer, industrial, and telecommunications applications.

P4KE540-B is engineered with a diode bridge rectifier, which has a fast turn-on response time. It features an integrated, voltage-dependent resistor to prevent follow-on current surge and enhance clamping performance. It also includes an anode-diode protection system to prevent direct reverse voltage application. The device also has a notch on the surface of its case that allows for secure mounting of the device to the circuit board or system case.

The P4KE540-B is designed to provide up to 540 watts peak pulse power dissipation, with a minimum stand-off voltage of 5.4V. It has a high holding voltage of 5.0V, a low holding current of 50mA, and an insulation resistance of 1×1011Ω. It also has a thermal resistance of 6.14°C/W and an operating temperature range of -55°C to +150°C. Its features make the P4KE540-B suitable for applications in a wide range of industries such as automotive, medical electronics, communications, consumer electronics and industrial electronics.

P4KE540-B TVS diodes work by clamping voltages above the device\'s breakdown voltage. By connecting the TVS diode between an input voltage source and the circuit ground, the TVS diode works to protect the circuit from transient voltages larger than the breakdown voltage. The device is able to do this because its breakdown voltage is much lower than the breakdown voltage of the circuit the TVS is protecting. The device is designed to clamp the voltage by sensing current spikes and quickly responding to them to divert the voltage away from the protected circuit.

Once the current has been diverted, the voltage is clamped back to the safe range. The diode bridge design allows for the bi-directional capability, offering protection against voltage transients from either direction. The device also has a large capacitance range, which results in increased protection and high surge current capacity. The increased capacitance range also allows for faster restoration of the circuit\'s voltage in the case of a transient.

The P4KE540-B is capable of effectively suppressing lightning, surge, and transients from either direction on a single line and protecting circuits from voltage transients in both high voltage and sensitive electronics applications. The TVS diode is an ideal protection device, providing superior protection and reliability in a wide array of applications.
