TVS (Transient Voltage Suppressors) diodes are a type of specialized electronic component designed to protect sensitive electrical circuits from voltage spikes and other on-chip induced surges. The ATV30C101J-HF is a TVS diode ideal for protecting communication, consumer, computer, and industrial applications. This diode is ideal for applications that require protection from high voltage spikes, including surge protection for notebooks, ultrathin PCs, gaming consoles, and displays.

The ATV30C101J-HF is an axial-leaded device (lead type) and designed to deliver up to 6.7kW peak pulse power in a 200mΩ series resistance (Zzt). Its unidirectional protection is offered in three voltage classes: 6.8 volts, 10 volts, and 16 volts.

The ATV30C101J-HF has been designed to possess a wide operating temperature range of -65C to 125C and optimized for automation placement in today’s high speed assembly operations. The device is also equipped with an electrically isolated backplate, which provides low parasitic inductance and opposite polarity protection for added flexibility in applications.

The basic working principle of the ATV30C101J-HF is to clamp the surge voltage below the forward breakdown voltage of the device. It performs this function by using a shunt direction of current flow. When the voltage rises quickly, the shunt trips, allowing current to flow through the TVS diode. This current limits the surge voltage to the forward bias voltage of the diode while the load remains protected.

The working principle of TVS diodes can be broken down into two main processes; the absorption process and the diverting process. In the absorption process, excess energy from the surge is absorbed by the diode and dissipated by its internal resistance. The diverting process occurs when the diode\'s PIV (peak inverse voltage) is exceeded, causing it to divert the excess current away from the primary load.

The ATV30C101J-HF is ideally suited for protecting sensitive communication, consumer, computer, and industrial applications from high voltage spikes that could cause permanent damage. By providing 6.7kW peak pulse power along with a 200mΩ series resistance and an electrically isolated backplate, the ATV30C101J-HF offers reliable protection from a wide range of voltage surges.
