TVS (Transient Voltage Suppressor) Diodes are commonly used for the protection of circuits from high-energy transients. TVS Diodes can quench the surge voltage generated due to lightning strikes, switching surges, or any kind of over-voltages. The SMDA05C-4/TR7 is a 5.0V Transient Voltage Suppressor from ON Semiconductor. Its package is a DO-214AC (SMC) which is a molded epoxy JEDEC DO-214AC type. It has a superior protection against lightning as well as inductive loads and a peak pulse power of 1000 Watts.

Application Fields

The SMDA05C-4/TR7 can be used in a variety of applications. It is highly suitable for use in automotive and consumer electronics. Additionally, it can be used in computer applications, especially for protection against ESD (Electrostatic Discharge). It is also suitable for applications where pulse power protection is required.

Working Principle

TVS diodes work on the principle of avalanche breakdown. They are basically PN junction diodes made up of two regions between the P-type and N-type semiconductors. When an external voltage is applied and the current is increased, the PN junction generates a strong electric field. This increases the potential barrier, and eventually, when the threshold voltage is crossed, the barrier breaks down and current flows through the diode. This phenomenon is known as avalanche breakdown.

The SMDA05C-4/TR7 TVS diode features a low breakdown voltage of 5 V and a reverse standoff voltage of 4.1 V. It has a maximum peak pulse current of 375 A and a maximum clamping voltage 1.6 V.

The TVS diode features the following features: it has an extremely fast response time of < 1.0 ns to respond to the transients; it can handle high levels of power; and it provides superior spike protection. Moreover, the TVS diode is designed to limit the peak pulse current in case of an over-voltage event.
