TV30C540J-G is a diode used as an overvoltage protection device, belonging to the category of Transient Voltage Suppressor (TVS) diodes. Its primary application field is the protection of electrical and electronic components and circuits from damagingly high voltages due to electromagnetic interference (EMI) or electrostatic discharge (ESD).

TV30C540J-G comes with a number of beneficial features which make it an ideal choice for overvoltage protection:

• It is bidirectional, able to protect against positive or negative overvoltages.
• It is capable of absorbing up to 500W of peak power.
• It has a low capacitance of only 0.1pF and a capacitance temperature coefficient of just 0.25pF/°C.
• It has an ultrafast 3.5ns response time.
• It is enclosed in a small SOD-523 SMD package.

The working principle of TV30C540J-G is relatively straightforward: during normal operation (i.e., when the input voltage is below its rated standoff voltage), the diode is virtually an open circuit, meaning there is no current flow. When the input voltage exceeds its rated voltage, however, the diode switches on and begins conducting current, thus limiting the voltage across its terminals below the breakover voltage by forming a low-resistance, high-current path.

TV30C540J-G, due to its favourable parameters and highly robust design, is a reliable choice for overvoltage protection in a wide range of applications, from consumer electronics and automotive components to telecommunications equipment and industrial automation systems.
