TVS (transient voltage suppressors) diodes are electronic components that are used to protect electronics against damage caused by the sudden release of energy or voltage. They are especially important in applications where there is a risk of an electrical overshoot or a sudden increase in voltage. The SMAJ100CAHE3/5A is an example of a TVS diode, specifically designed for use in automotive, telecommunications, and industrial applications.

Application field

TVS diodes like the SMAJ100CAHE3/5A can be used as voltage protection devices in a variety of applications. They are commonly used in automobile and industrial systems for overvoltage spike protection, in telecommunications systems for lightning protection, and in audio and video equipment for ESD (electrostatic discharge) protection. The SMAJ100CAHE3/5A has an operating range of 6.8V to 12V, which makes it particularly suited for automotive applications.

Working principle

TVS diodes like the SMAJ100CAHE3/5A are designed to respond quickly to high voltage transients by allowing a large amount of current to flow in a single direction. When it detects an overload in a circuit it quickly switches from its forward conduction state to its reverse conduction state, diverting the excess current to ground. This keeps the circuit from being damaged by too much voltage.

TVS diodes like the SMAJ100CAHE3/5A are typically bidirectional, meaning that they can protect against overvoltages in either direction. They also provide protection against ESD, which is especially important in applications that involve people moving around in static environments. The SMAJ100CAHE3/5A is rated for a peak pulse power of 1.7 kV, making it a suitable choice for many of these applications.

Conclusion

The SMAJ100CAHE3/5A is an example of a TVS diode, specifically designed for automotive, telecommunications, and industrial applications. It is designed to quickly respond to high voltage transients and divert the excess current to ground, protecting the circuit from damage. The SMAJ100CAHE3/5A is bidirectional and provides protection against ESD as well. With its wide operating range and high peak pulse power, it is a suitable choice for many applications.
