Transient Voltage Suppressors (TVS) or Transient Voltage Surge Suppressor (TVSS) such as the 30KP240CA-TP, are a form of electronic protection device designed to protect equipment from damage due to voltage transients or spikes. They are often employed where lightning is a common occurrence, or in noisy RF applications. By definition, a transient is an abrupt, short-term change in potential which can result in disruption, damage, or destruction of electrical or electronic equipment.

TVS diodes are typically used to protect against common-mode and differential-mode transients, helping to protect the circuits from damage, disruption, or destruction from overvoltages. They are used in I/O ports, power supplies, and digital circuits as well as medical equipment, consumer electronics, telecommunications, industrial and automotive electronics.

The 30KP240CA-TP is a Transient Voltage Suppresor (TVS) diode with an exceptionally low clamping voltage and excellent electrical performance, beyond what can be expected from a standard TVS diode. It features a surge rating of 240A, an operating temperature range from -55°C to +125°C, RoHS compliance, and a maximum peak pulse current of 360A. It is ideal for applications requiring protection and clamping of transient surges.

The structure of the 30KP240CA-TP consists of two parts: the reverse-blocking or TVS diode and the avalanche breakdown diode. The breakdown diode is defined as the zener diode, responsible for the reverse polarity voltage breakdown that sets the clamp voltage. The TVS diode is responsible for clamping the voltage at a fixed value when it exceeds the breakdown voltage of the zener diode.

The 30KP240CA-TP is designed to operate in the event of an overvoltage transient, allowing the diode to clamp the voltage quickly and effectively. When the voltage exceeds the breakdown voltage, the avalanche breakdown diode triggers the TVS diode to start conducting. This allows current to flow in the opposite direction, clamping the voltage to the set breakdown voltage. The clamping voltage is maintained until the input voltage returns below the breakdown voltage. As soon as the voltage returns to normal, the diode stops conducting and the circuit is protected from the peak voltage.

Overall, the 30KP240CA-TP Transient Voltage Suppresor (TVS) diode is suitable for a wide range of applications including RF, consumer electronics, automotive electronics, medical equipment, and telecommunications. It features a surge rating of 240A, an operating temperature range from -55°C to +125°C, RoHS compliance, and a maximum peak pulse current of 360A. It is designed to clamp the voltage quickly and effectively in the event of an overvoltage transient, allowing the circuit to be protected from the peak voltage.
