TVS (Transient Voltage Suppression) Diodes protect sensitive electronic circuits from voltage transients caused by Electrical Fast Transients (EFTs), Lightening, and Electrostatic Discharge (ESD). The ATV06B191J-HF was specifically designed to protect against these events. This includes pins 3-10 on the Surface Mount Device (SMD) and pins 1-7 on the Through Hole (TH) device.

The ATV06B191J-HF utilizes a uniquely designed Zener diode array that is able to activate in microseconds when an incoming transient voltage is sensed. This drastically limits the duration and amplitude of the voltage event by steady state clamping of the voltage. In contrast to this, a regular Zener diode and most other surge suppressors require microseconds to milliseconds before responding to a high energy voltage spike.

The ATV06B191J-HF is able to protect against both low-frequency and repetitive ESD pulses. It is also able to provide superior transient protection from a single strike of lightning, protecting the sensitive components of electronic circuitry. The device is qualified to the following standards:

• IEC 61000-4-4
• IEC 61000-4-5
• IEC 61000-4-2 Air 15kV, Contact 8kV

Its design also makes it compatible with both telecommunications and networking applications. The SMD device is a space-saving footprint, measuring just 2.1mm x 1.6mm. Meaning it can be installed within tight-fitting spaces for electronic devices. This makes it suitable for cell phones, PDAs, and other handheld devices that require surge and ESD protection for their sensitive internal components.

The ATV06B191J-HF is highly robust and is a low-power solution for protecting connected equipment. It has a low power rating of <100mW and offers practically surge free operation with an enter input current leakage of <10uA. Its flexibility to operate in both low and high temperature environments (-40°C to 125°C) also makes it an ideal choice for rugged applications in military, aerospace, and industrial equipment.

The ATV06B191J-HF is a highly reliable form of surge protection that is compliant to the stringent requirements of the electronic industry. It offers superior protection from transient events such as EFTs and lightning, is small enough to fit into most spaces, is highly reliable, and provides cost effective protection for sensitive electronics.
