TVS - Diodes

Transient Voltage Suppressor (TVS) diodes are semiconductor devices designed to protect electronic circuits against voltage transients and surges that are higher than the normal operating voltage levels. A TVS diode is essentially two back-to-back Zener diodes connected in series. The P4KE62C-E3/54 is a unidirectional TVS diode specifically designed to protect equipment from voltage surges in industrial, automotive, and telecom applications.

Application Field and Working Principle

The primary application field of the P4KE62C-E3/54 is in protecting power supply circuits from ESD and lightning transients. These two types of surges arrive at different times and have different waveforms, so manufacturers design the diode to offer protection from both. The diode can be used in a positive or negative line, and its surge capability is about 8kV for a peak pulse of up to 10V. This provides excellent protection against spikes or surges in an application\'s voltage.

The P4KE62C-E3/54 works on the principle of "avalanche voltage breakdown". When the applied voltage exceeds the reverse breakdown voltage of the diode, a large current flows through it and the diode clamps the voltage to a certain level. This prevents the voltage from reaching the critical level which may damage the IC or other components. The peak power rating of the P4KE62C-E3/54 is 6W and it can be used in various different applications.

Due to its high surge protection capability, the P4KE62C-E3/54 is ideal for automotive applications such as Electronic Control Units (ECU), engine computers, junction box, and distributor modules where ESD and surge protection is essential. In industrial applications, the diode is used in operations such as process control and power supplies for air conditioners, washing machines, and other household appliances.

The diode is also used in telecommunications applications such as network routers, modems, and surge protectors. It provides excellent protection against voltage transients and surges for the telecom equipment which helps maintain the stability and reliability of the network.

The P4KE62C-E3/54 is a unidirectional diode designed for protection against overloads and inductive transients. It has a low leakage current and its operating temperature range is from -55°C to 175°C. The diode is available in surface mount and through-hole options and its maximum reverse clamping voltage is 62V.

The device is designed for reliable protection across a wide temperature and voltage operating range, and it is UL recognized. It is ideal for use in consumer, automotive and industrial electronic devices, allowing for reliable protection from voltage transients and surges.
