TVS - Diodes

SA5.0A A0G Application Field and Working Principle

TVS (transient voltage suppression) diodes are used in electronic circuits to protect them from current or voltage spikes that could damage or cause failure. When a sudden power surge, static discharge, electromechanical contact, or electrical transients occurs, the surge current spikes to a higher level than normal and the TVS diode steps in to lower the overvoltage.

Electronic equipment is subject to a variety of risks from overvoltages due to power surges, lightning strikes, electrostatic discharges, and other electrical transients. The transient voltage suppression (TVS) diode is designed to protect sensitive electronic components from such damaging voltages. TVS diodes provide an efficient and cost-effective surge protection solution for a variety of products. TVS diodes are available in a range of technology types such as unidirectional and bi-directional types.

The SA5.0A A0G TVS diode is an unidirectional diode designed to protect against overvoltage transients in both positive and negative polarities. It has a maximum breakdown voltage of 5V and a peak power of 25W, which makes it suitable for a wide range of operating voltages. It is optimized for high power applications, with a low dynamic resistance and fast switching speeds that help to protect against voltage surges.

The working principle of the SA5.0A A0G TVS diode is based on the avalanche breakdown principle in which a Zener diode provides a variable voltage output when a reverse biased voltage is applied to the diode. When an over voltage transient occurs, the breakdown voltage of the diode is exceeded and the diode begins to conduct. The diode will then typically divert any over voltage on the output or connected components to its own protected ground connection.

The SA5.0A A0G TVS diode is a versatile surge protection component that offers high performance protection for a variety of applications. It is available in a variety of packages and configurations, making it suitable for use in a wide range of applications. It is ideal for use in power supplies, computers, telecommunication systems, consumer electronics and many other applications.
