1KSMB30CAHR5G

TVS diodes, also known as Transient Voltage Suppressors, are an important group of components used to control overvoltage and overcurrent spikes in circuits. They are capable of withstanding high surge currents and voltages that are beyond the normal operating limits of the circuit, protecting it from damage. 1KSMB30CAHR5G is one such example of a TVS diode.

1KSMB30CAHR5G is a unidirectional TVS diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other electrical disturbances. It has a symmetrical bidirectional Working Voltage of 28V and an average Peak Power Dissipation of 30 Watts. The total peak power pulse may exceed 30 watts, but not by more than two times. This makes it suitable for protecting components against high voltage and current spikes, ensuring uninterrupted operation of the circuit.

The main application field of the 1KSMB30CAHR5G diode is in the protection of electronic devices against environmental and man-made voltage transients. It can be used in various areas such as automotive, industrial, consumer, and medical. It can be used in power supplies, DC/DC converters, data lines, and telecommunications equipment. It can also be used for surge suppression in circuits attached to monitoring devices, such as accelerometers and gyroscopes.

The working principle behind the 1KSMB30CAHR5G diode is the zener-breakdown effect. When a high surge voltage is applied to the diode, it will reach a certain breakthreshold level and become highly conductive. At this point, the diode will conduct current in an order of magnitude greater than its normal operating current, quickly limiting the surge voltage.

When the surge subsides, the diode will return to its non-conductive state. This is because the breakthreshold is significantly higher than the diode’s normal operating voltage. The diode will then dissipate the excessive energy in the form of heat, again protecting the circuit from overvoltage and overcurrent spikes.

In summary, 1KSMB30CAHR5G is a unidirectional TVS diode designed to protect sensitive electronic equipment from excessive voltages and current surges. It is suitable for use in automotive, industrial, consumer, and medical applications. The diode works by conducting current in an order of magnitude greater than its normal operating current, quickly limiting the surge voltage. When the surge subsides, the diode will return to its non-conductive state and dissipate the excessive energy in the form of heat.
