TVS - Diodes are an integral component in a large variety of electronic applications, from consumer devices to automobiles to military and aerospace applications. A TVS Diode, or Transient Voltage Suppressor Diode, is a semiconductor diode designed specifically for protecting sensitive electronics against transient overvoltages from electrical surges. One such device, the ATV30C131J-HF, meets Automotive AEC-Q101 qualified and is presented in a small 1.3 mm x 1.1 mm flat TVS package. This device offers a wide range of protection features, as well as low insertion loss and low clamping voltage.

ATV30C131J-HF is well suited for use in the automotive environment, as it is AEC-Q101 qualified. It is reliable over a wide temperature range (-40°C to 85°C) and provides up to 1500 Watts of peak pulse power dissipation. Additionally, it provides a fast response time used to keep the circuit protected from transient voltage, with response time of less then 1.0 nanoseconds. This makes it well suited for use in a variety of automotive applications, including those where fast rising transients and over-currents may occur.

The ATV30C131J-HF is an unidirectional device with a rated working voltage of 13 volts. It can be configured in parallel with a resistor to generate multiple levels of protection. The device has an On-Chip voltage clamping voltage of 31 volts, a reverse Stand-Off Voltage of 11 Volts, and a Reverse Breakdown Voltage of 13 Volts. The leakage current at Maximum Reverse Voltage (MRV) is 200 nA. It also offers superior protection for static electricity by blocking up to 1500 Volts ESD from both in-line and cross-line discharges.

The ATV30C131J-HF works on the principle of avalanche breakdown. When exceeding the Reverse Breakdown Voltage of 13 Volts, the diode enters a state of breakdown, allowing current to flow through it at low voltage and high current density resulting in voltage clamping effect. This results in low clamping voltage and allows the device to quickly absorb and dissipate the transient voltage, thus providing protection to the circuit. This device can also be used in a low clamping configuration for applications involving pulse ringing suppression or for AC power line protection where the device can swiftly respond to negative or positive going transients.

The ATV30C131J-HF is a robust and reliable device capable of withstanding multiple transient overvoltage events. It can be effectively used in a wide range of automotive applications, from protecting low-voltage components from electrical surge, to providing improved ESD protection for all circuits, including control, power and signal circuits. With its small package size, fast response time, wide temperature range and low clamping voltage, the ATV30C131J-HF is well suited for use in a variety of automotive electrical applications.
