Transient-Voltage-Suppression (TVS) diodes are an important element of circuit protection designs. TVS diodes protect against transient voltage surges by limiting the maximum voltage spike and clamping it to a level below the breakdown of the protected component. The JAN1N6164A is a unidirectional TVS diode designed to protect sensitive electronic components from over-voltage transients. This TVS diode is well suited for automated mounting in most applications due to its low profile design and wide operating temperature range.

The JAN1N6164A is a part of the popular media diode series available from QVS-Tech. It is designed to provide superior protection against voltage transient surges in consumer electronics and TVs. This diode is capable of suppressing even the most extreme voltage transient events, such as lightning strikes and power fault disturbances. It can handle transient voltage levels up to 30kV and its low capacitance makes it suitable for high-speed applications such as Ethernet, USB, HDMI, and other high-speed digital/analog interfaces.

The JAN1N6164A has proven reliability. Its low profile design allows for mounting in difficult locations and applications. Its low capacitance helps to minimize signal degradation in high-speed data lines, making it an ideal solution for multi-mode signal protection. Its low leakage current and low clamping voltage also make the JAN1N6164A ideal for voltage spike protection in applications with limited power budgets. The diode comes in a SOT-23 SMD package and has a maximum power dissipation of 350 mW and a maximum break-down voltage of 64 V.

The working principle of the JAN1N6164A is straightforward and consists of two main components. It is mainly composed of a junction diode and a Zener diode, with the junction diode providing protection against high positive voltage spikes and the Zener diode providing protection against high negative voltage spikes. When a voltage spike of any polarity enters the circuit, the diode conducts and the Zener diode clamps the voltage to a desired level. The junction diode then shorts out the voltage spike allowing it to be dissipated into the ground. The breakdown voltage of the diode is set by the Zener diode, which allows it to hold the desired level even at high levels of voltage spikes.

The JAN1N6164A is a great solution for protecting circuits with limited power budget from voltage transient events such as ESD and lightning strikes. Its low profile design, wide operating temperature range, and excellent protection performance make it an ideal choice for applications in consumer electronics and TV applications. The principle of operation and excellent protection capability make it an ideal choice for voltage transient protection.
