TVS - Diodes

TVS (Transient Voltage Suppressors) are electrostatic discharge (ESD) protection devices that protect electronic components from ESD, electrical fast transients (EFT) and lightning induced surges. TVS diodes are devices which protect from over-voltage transients and also protect from reverse-voltage transients.

The ATV04A141J-HF diode is one such TVS device. The product is from ON Semiconductor and is ideal for ESD protection in high-speed differential Data Bus applications which have a bandwidth of over 66MHz. It has an ESD protection of up to 8 kV (Human Body Model) and up to 16 kV (IEC 61000-4-2 air gap discharge).

The ATV04A141J-HF is a bidirectional device which offers fast, low clamping voltage performance. It also has a very low leakage current which helps to preserve battery life. This low leakage current is supported by the low forward voltage drop of the diode. The diode is also designed to protect against low charge transients and is RoHS complaint.

The ATV04A141J-HF diode is designed to protect high speed data systems which are sensitive to ESD, lightning induced surges and electrical fast transients. The diode is also designed to provide low capacitance, low inductance and high peak pulse current handling capability. It has a peak pulse current rating of 4.3A (8/20µs) and can be used in applications with a wide operating temperature range (-55°C to +150°C).

The ATV04A141J-HF diode works on the principle of a Zener diode or avalanche diode. When the voltage of the diode rises to the breakdown voltage (or the Zener voltage) of the diode, the diode enters the breakdown region. When this happens, the diode starts to conduct and the current in the diode starts to increase. During this time, a voltage drop occurs in the diode and the voltage across the diode is reduced to a safe level. This is called the clamping voltage. The diode can provide this protection to circuits from over voltage transients and it also helps to prevent it from getting any electrostatic discharges.

In summary, the ATV04A141J-HF diode is a TVS device from ON Semiconductor which is designed for high-speed differential Data Bus applications. It is a bidirectional device which has a low clamping voltage, low leakage current and is RoHS complaint. It offers ESD protection of up to 8 kV and supports a wide operating temperature range of -55°C to +150°C. It is designed to protect high speed data systems which are sensitive to ESD, lightning induced surge and electrical fast transients. The diode works on the principle of Zener diode or avalanche diode for providing protection to circuits from over-voltage transients.
