TV50C121JB-G

TVS - Diodes

Transient voltage suppressor (TVS) diodes are a type of semiconductor protective device that is designed to protect sensitive electronic components and systems from voltage spikes, high voltage transients, and other forms of overvoltage protection. TVS diodes are often used in automotive, industrial, and consumer electronics applications to protect circuits from damaging voltage transients. TV50C121JB-G is a TVS - Diode offered by STMicroelectronics.

TV50C121JB-G Application Field and Working Principle

TV50C121JB-G is designed for transient protection of electronic equipment against over voltage transients caused by lighting, electrostatic discharge (ESD), inductive switching, etc. It is designed to protect data and signal lines, such as USB ports, HDMI ports, etc. The device is available in a 0603 packaging and is AEC-Q101 qualified for automotive applications. It has a low capacitance of 5.3 pF and can withstand voltages up to 150 V.

The TV50C121JB-G is designed to clamp the voltage peak to a safe level, which limits the current that flows into the protected circuit. It works by providing a highly conductive low impedance path for the transient voltage when it reaches a breakdown voltage. The breakdown voltage is determined by the breakdown voltage rating of the device, which is typically around 2 to 3 volts.

The TVS diode has a breakdown voltage that is typically lower than the nominal working voltage of the device, which means it will not allow voltages above the breakdown voltage to pass. When the voltage reaches the breakdown voltage, the diode begins to conduct and the voltage is clamped down to a safe level. The TVS diode also has a clamping voltage that is typically higher than the breakdown voltage, which helps protect the device and components from overvoltage transients.

The TV50C121JB-G is designed to protect against ESD, inductive switching, and other high voltage transients. It has a fast response time of 1.2 ns, which helps to provide protection from voltage transients and spikes. The device also has a low quiescent current of 0.2 uA, which helps to reduce power consumption.

The TV50C121JB-G is designed for use in automotive, industrial, and consumer electronics applications. It is a robust, reliable, and cost effective solution for protecting the sensitive components in these applications. The device can also be used for Surge and transient voltage protection.
