TVS (Transient Voltage Suppressors) diodes are an essential component in many electrical designs and the TV30C141J-G is a widely-used, reliable component for protecting sensitive parts from voltage “spikes” or other short-term electrical disturbances. It provides protection from high-voltage transients, helps ensure the safe operation of delicate circuitry, and is suitable for a variety of consumer, automotive, and industrial applications.

Application Field of TV30C141J-G

The TV30C141J-G is a unidirectional TVS diode. Its most common application area is consumer electronics, where it is used to protect against surges such as overvoltage, electrostatic discharge (ESD), and line inductive transients. This type of diode can also be used in automotive and industrial electronics to protect against lightning-induced overvoltage transients and inductive transients.

The TV30C141J-G has a breakdown rating of 30 volts, a peak pulse power rating of 141 watts per line, and a pulse discharge current of 16 amps (1/10 of 8/20 microsecond waveform). The device has a low clamping voltage, making it suitable for use in low-voltage applications. It is also provided in the small, low-profile SMA package, meaning that it can fit into a range of designs.

Working Principle of TV30C141J-G

The TV30C141J-G diode works by providing a low-impedance path to ground in the event of a transient voltage surge. When the voltage across it exceeds its breakdown voltage (typically 30 volts), the diode is effectively short-circuited, limiting the voltage across the protected part of the circuit and allowing the excess energy to be dissipated as heat. By reducing the voltage across the protected part of the circuit to a safe level, the diode prevents damage to sensitive components and helps ensure that the circuit operates as intended.

The TV30C141J-G is a unidirectional diode, meaning that it only allows current to flow in one direction (from its anode to its cathode). This is important, as it allows the device to provide voltage protection in applications where the polarity of the supply voltage is known. If a diode were to allow current to flow in both directions, the end result would be a short-circuit, which could potentially damage the protected device or circuit.

The TV30C141J-G also provides excellent surge protection characteristics. It has an excellent peak pulse power rating of 141 watts and a pulse discharge current rating of 16 amps (1/10 of 8/20 microsecond waveform). This ensures that the diode can effectively absorb high-voltage transients without causing damage to the protected device or circuit.

In summary, the TV30C141J-G is an excellent choice for those looking to protect sensitive electronic components from voltage “spikes” or other short-term electrical disturbances. With its wide range of applications, low-profile design, and excellent surge protection characteristics, this diode is an ideal choice for both consumer and industrial applications.
