TVS (Transient Voltage Suppressor) diodes are typically used to protect media vulnerable to transient events, sometimes referred to as ESD (electrostatic discharge) or EFT (electrical fast transients). The TV30C191J-G is a unidirectional TVS diode commonly used in clamping applications, with a peak pulse power rating of 1.5kW.

What Is TV30C191J-G?

TV30C191J-G is a unidirectional TVS diode that functions by conducting current only in one direction. It features a peak pulse power rating of 1.5kW and an operating temperature range of -40 to +85°C. It is a component commonly used in clamping applications.

Application Field of TV30C191J-G

TV30C191J-G is commonly used for protecting circuits against transient events such as ESD or EFT. It is typically used in clamping applications where it can absorb current spikes and clamp transient events, thus helping to protect vulnerable components. It is also used in AC/DC applications, DC/DC applications and other industrial control applications. Besides, it is also used in high frequency signal input protection, automotive system protection, communications and consumer electronics equipment.

Working Principle of TV30C191J-G

When a transient event occurs, the TV30C191J-G diode rapidly conducts current in one direction and then switches off. This clamping action absorbs the current spike quickly and helps prevent damage to the circuits. The diode is designed to dissipate power through its own internal resistance, thus protecting vulnerable components from damage. As the diode is unidirectional, meaning it conducts current in only one direction, it prevents the back flow of current, thus providing protection from both positive and negative transients.

Conclusion

The TV30C191J-G diode is a unidirectional TVS diode that provides protection from transient events such as ESD and EFT. It is commonly used in clamping applications to absorb current and dissipate power. Its peak pulse power rating of 1.5kW makes it suitable for use in AC/DC, DC/DC and other industrial control applications, as well as in automotive, communications and consumer electronics equipment. The diode is designed to conduct current in one direction only, thus providing protection from both positive and negative transients.
