Transil (TVS – transient voltage suppression) diodes protect sensitive equipment from overvoltages, which consist of high frequency noise. These overvoltages may occur due to switching operations, incoming lightning discharges or electrostatic discharge (ESD).
30KP48CA-TP series is a low capacitance, high surge rated Transient Voltage Suppressor (TVS) diode. It is suitable for various applications requiring overvoltage transient protection and system-level ESD protection. The TVS-diode features a 650W (8/20µs) peak pulse power rating, a 48V breakdown voltage and a low typical capacitance of 0.65pF. It is suitable for protecting I/O and communication ports like USB, RS232, HDMI, etc.
In general, Transil diodes are bidirectional devices, with a low dynamic resistance (RDYN) and fast response time (trr). The components have an integrated protection element and anode-cathode junction. Internal circuitry ensures maximum switching speed and minimal power dissipation in order to prevent device overheating.
The 30KP48CA-TP is an unidirectional device, meaning it only conducts current in one direction. It has a peak pulse current rating of 28 A and an operating junction temperature range of -55°C to 150°C. When the junction is exposed to a fast, high energy pulse, the junctions breakdown and the electrical energy is absorbed. The peak breakdown voltage of this TVS-diode is 48V.
The capacitance of the TVS-diode is very important for the application it is being used in. The capacitance of the 30KP48CA-TP is 0.65 pF, which makes it suitable for very high frequency applications. The TVS-diode also dissipates very low power levels, making it suitable for applications with an total power dissipation requirement of 0.1W or less. Moreover, its high surge withstand capability ensures that the device is able to survive high energy surges without any damage.
The 30KP48CA-TP TVS-diode is suitable for the following applications: USB, RS232, and HDMI ports, telecom/datacom ports, consumer/professional wireless audio cables, automotive, medical, and IT equipment. The device can also be used for other applications where protect sensitive components from ESD, electrical transients, and other surge related events.
In conclusion, the Transil (TVS – transient voltage suppression) 30KP48CA-TP diode provides excellent overvoltage protection and ESD protection. It has a 650W (8/20µs) peak pulse power rating, 48V breakdown voltage, low typical capacitance of 0.65pF and a peak pulse current rating of 28A. This TVS diode is suitable for protecting various types of ports, including USB, RS232, HDMI, and others. In addition, it is also suitable for use in applications such as consumer/professional wireless audio cables, automotive, medical and IT equipment.
