TV02W140B-G diodes are a type of TVS (Transient Voltage Suppression) diode or transil, specifically designed for protection from over-voltage transients such as ESD (electrostatic discharge), lightning, RF, power induction and other surge sources. TVS diodes provide protection in electronic circuits by clamping the voltage level to prevent destructive surges.

TV02W140B-G diodes are used in a variety of applications including automotive, industrial, communications and consumer electronics. They are commonly found in cellphones, smartphones, laptops, tablets, smart speakers, servers, power supplies, power over Ethernet (PoE) systems and other consumer electronics equipment.

TV02W140B-G diodes are versatile in their application. They can be used to protect against ESD, noise, or inductive spikes, and can be used as a part of the signal conditioning circuit, as well as for signal protection across a wide range of frequencies. They can also be used in high-voltage applications, such as power supplies and AC/DC converters, where they provide over-voltage protection.

TV02W140B-G diodes are working based on the avalanche effect. When a surge or transient voltage is encountered, the diode enters the "avalanche" or "Zener" breakdown mode and clamps the voltage to a predetermined level. This is known as the "clamping voltage". As the diode clamps the voltage level, the excess current is conducted away from the protected circuit and dissipated through the diode, preventing damage to the circuit.

The main component of the TV02W140B-G diode is a zener diode, composed of P-type and N-type layers. When the diode starts conducting, the P-type and N-type layers form a junction. This junction acts as a one-way valve, allowing current to flow from one layer to the other. When the diode is subjected to a surge or transient voltage, the junction breaks down and provides for a low-resistance conduction path, thus clamping the voltage to a predetermined level.

TV02W140B-G diodes are available in several variants, such as surface mount, axial lead, gull wing package and reverse mount. They can be used in a wide range of applications thanks to their wide operating temperature and frequency range, small package size and wide clamp range. They also offer high surge capability, fast recovery time, low capacitance, and ESD protection up to 25kV.

In conclusion, TV02W140B-G diodes are an important component in the field of transient voltage suppression. They are used in a wide range of applications and provide a cost effective solution for protecting circuits from destructive over-voltage transients. Thanks to their wide operating temperature and frequency range, small package size and wide clamp range, they are able to provide superior protection in the most challenging applications.
