TVS - Diodes, also known as transient-voltage-suppressors (TVS’s), are devices which are designed to protect sensitive circuits from electrical transients, or surges, that may arise in the power supply system. In particular, TVS-diodes are used in applications where over voltage protection is required, such as computer systems and telecommunications equipment. The SMDA05C-4E3/TR7 device is a transient-voltage-suppressors (TVS’s) diode specifically designed for use as an over voltage and over current protection in numerous application areas.

The SMDA05C-4E3/TR7 diode is packaged in a standard lead-frame TO-252:3-P package. The device has an operating temperature range of -55°C to +150°C and is rated for a maximum peak power dissipation of 6.6W. The SMDA05C-4E3/TR7 has a maximum reverse surge withstand capability of 5A (8/20 μs) and a maximum peak pulse current of 30A (1ms). The diode also has a maximum reverse breakdown voltage of 5.0V and a maximum allowable operating current of 1.0mA at +125°C.

The SMDA05C-4E3/TR7 is a unidirectional device which provides over-voltage and over-current protection for a wide range of applications. It is well suited for use in applications such as computer, telecom and industrial electronics, as well as automotive and military applications. It has been designed to protect against voltage transients caused by inductive and non-inductive loads, such as those caused by motor spikes, as well as protecting sensitive circuits from over-currents which may arise in certain types of equipment.

The working principle of an SMDA05C-4E3/TR7 diode is quite straightforward. When a voltage transient or current surge occurs, the diode will act like a switch, allowing current to flow in only one direction. This in turn causes the excess current to be passed away from the sensitive circuit, protecting it from damage. The diode also helps to limit the maximum voltage that the circuit may be subject to.

The SMDA05C-4E3/TR7 diode is an effective solution for the protection of sensitive circuits. It is well suited for use in various types of equipment, including computers, telecom and industrial electronics, as well as automotive and military applications. The device is an easy to install solution which provides reliable protection against voltage transients and over-currents.
