SMA5J30A-M3/5A

TVS diodes, also known as Transient Voltage Suppression, are used to protect sensitive electronic devices from voltage transients that exceed the normal operational voltage of the device. They are commonly used to protect against electrical surges in power plants, automotive, and industrial equipment. The SMA5J30A-M3/5A is a TVS diode that offers protection against voltage transients and surges up to 5 Amps. It is a vitreous silicate glass overcoated TVS diode with a unidirectional bidirectional 30A pulse peak current rating.

The SMA5J30A-M3/5A has a variety of applications. It is primarily designed to protect against over-voltage or under-voltage conditions in automotive, industrial, and power-plant equipment. Furthermore, this tvS diode can be used to protect digital and analog circuits from electrostatic discharge that can damage sensitive components and circuits. It is also suitable for use in other applications such as surge suppression, over-voltage protection, and the protection of DC converters.

The SMA5J30A-M3/5A works by clamping the voltage transient at the clamp voltage, thus preventing further damage to the components. When a peak voltage surge occurs, the TVS diode begins to conduct current and provide a low impedance path for the transient current to dissipate. This process is known as clamping, and it helps to reduce the amount of current that can be passed through the circuit and protect the device from damage.

The SMA5J30A-M3/5A has a clamping voltage of 32V and an on-state voltage of 3.7V. The back-to-back diode configuration helps to reduce losses and provides a higher surge current rating. The diode also has a capacitance range of 16-50pF, which helps to reduce interference and provide reliable protection of sensitive components. It is also designed with a surge current rating of 30A for 10/1000 μs and a peak pulse current rating of 5A for 8/20ms.

In conclusion, the SMA5J30A-M3/5A is a TVS diode that offers protection against over-voltage and under-voltage conditions. It is designed with a clamping voltage of 32V and an on-state voltage of 3.7V and can provide reliable protection of sensitive components. The diode also has a surge current rating of 30A for 10/1000 μs and a peak pulse current rating of 5A for 8/20ms. The SMA5J30A-M3/5A is suitable for use in automotive, industrial, and power-plant equipment and is also suitable for use in surge suppression, over-voltage protection, and protection of DC converters.
