ATV30C150J-HF is a TVS (Transient Voltage Suppression) Diode, widely used to protect sensitive electronic equipment from voltage surges due to inductive or capacitive kick back. The device is designed to deliver ESD protection in a variety of applications, such as Automotive, Industrial, Medical, Energy Storage and Telecom equipment. With its fast response time (10 ns) and low leakage current (1 μA) this device provides exceptional ESD protection.The ATV30C150J-HF has an operating voltage range of 70 to 160 volts, a peak pulse current of 30 watts (at 10/1000 μS), and a typical clamping voltage of 30 volts (at 1.5 amperes). The device has a reverse stand-off voltage of 7 volts and a leakage current of 1 microampere. It has a temperature coefficient of -1.4 mV per ℃ and an operating temperature range from -55 to 150℃. It is made of a ceramic-filled epoxy package with two leads for easy connection.The ATV30C150J-HF is typically used in combination with a TVS Array such as the ATV30C110J-HF to provide additional protection. The TVS Array contains multiple channels of protection, and is designed to absorb multiple transient spikes and limit inductive kickback.The ATV30C150J-HF works by clamping voltages to a specific level. When a voltage surge occurs, the diode initiates a rapid clamping action, which prevents high voltage from damaging sensitive electronics. This clamping action is based on the application of the P-n junction, where a reverse bias voltage is applied to the semiconductor junction. This creates a curved depletion layer between the N and the P regions, which works to limit junction current. When a steady state voltage or a transient surge transits a value higher than the reverse breakdown voltage, the diode "clamps" the voltage to its clamped value, thereby protecting sensitive electronics against high voltage damage.The ATV30C150J-HF is a reliable and cost-effective solution for protecting circuits from over-voltage and transients. Its rugged construction and quick clamping response make it an ideal choice for a variety of applications, such as Automotive, Industrial, Medical, Energy Storage and Telecom equipment.
