TV15C170J-G devices are Smart ProtectorTM devices, which are Diode-TVS (Transient Voltage Suppressor) devices. Diode-TVS devices are unidirectional protection components that prevent voltage and current spikes from damaging sensitive electrical components. By redirecting and suppressing excessive voltage and current before it can reach sensitive equipment, diode-TVS components ensure maximum efficiency and prevent data loss.

The TV15C170J-G device is a Surface Mount (SMT) Diode-TVS component. This component is designed to provide protection for DC and AC power lines, and is suitable for applications that require high power protection, such as laptop computers, cellular phones, and other consumer electronics. It is a single line device capable of protecting against transient voltage up to 15V and maximum peak pulse current up to 140A.

The working principle of the TV15C170J-G device is based on the phenomenon of reverse breakdown. This phenomenon occurs when the reverse bias voltage of a semiconductor junction exceeds a certain threshold. When this happens, high current flows through the junction. The TV15C170J-G device uses this phenomenon to redirect and suppress excess voltage and current.

When voltage or current spikes occur, the small junction capacitance of the TV15C170J-G diode-TVS component causes it to be reverse biased. This reverse bias causes the device to initiate a current flow, which quickly increases to its maximum peak pulse current capability. As the current increases, the junction capacitance also increases, resulting in a rapid and sufficient voltage clamping of the transient. Thus, the TV15C170J-G device provides excellent protection against transient over-voltage and over-current spikes.

The TV15C170J-G device is designed to provide maximum transient protection in high power applications while minimizing power consumption. In addition, the device requires no external components, thus simplifying system design and reducing costs. With its fast response time, the TV15C170J-G device is an ideal choice for applications in which high power protection is necessary.
