TVS (Transient Voltage Suppressor) diodes can both absorb and regulate electrical surges. They are commonly used for biomedical, automotive, and consumer electronics applications, and are often used to protect against transient over-voltage and/or transients. The SA16AHE3/73 TVS diode is an efficient and reliable device that works to shield electrical systems from harm. Here, we will discuss the application areas the SA16AHE3/73 and its working principles.

Application Fields

The SA16AHE3/73 is an electrical surge suppressor that is often used as a protection device in consumer electronics and automotive industries. It is mainly employed in these two industries because its low surge voltage and low leakage current make it ideal for controlling and managing low-power to medium-power electrical systems. In addition to using it in these industries, the diode is also employed as a protective device for medical equipment, particularly those used in intensive care units. It can also be used as a circuit protection device in automotive and AV systems.

For consumer electronics, the SA16AHE3/73 can be used in electronic control boards, modems, mobile phones, automotive avionics, and on-board Voltage Protection (OVP) control boards. This gives it a wide range of applications, including computers, digital display systems, drones, and robotics. Automotive applications of the diode include engine control, dashboard, and navigation systems.

Working Principle

The SA16AHE3/73 is a voltage-controlled diode with the ability to effectively control and regulate the flow of electrical currents. When an electrical system is exposed to rising or falling voltages, the SA16AHE3/73 will automatically activate and protect the system from over-voltage surges and transients. Due to its low surge voltage and low leakage current, it provides an excellent level of protection for sensitive electrical systems.

The SA16AHE3/73 also utilizes a multi-junction design to guard against reverse-polarity conditions. This helps to protect the system from false triggering caused by accidental reverse-polarity trips. In addition, the diode also employs a silicon nitride passivated mesa that helps to protect against junction ablation, which can lead to a decrease in efficiency and operational stability.

The diode is composed of solid, construction-grade materials, providing excellent durability. This makes it highly suitable for applications in extreme environments, such as those found in automotive or medical instrumentation systems. The SA16AHE3/73 is also designed to be compatible with both lead-free and traditional SnPb soldering processes.

Conclusion

The SA16AHE3/73 TVS diode is an efficient and reliable device that works to shield electrical systems from harm. It is often used as a circuit protection device in consumer electronics, automotive, and medical equipment applications. With its low surge voltage and low leakage current, it can serve as an exceptional surge suppressor. Additionally, the device also utilizes a multi-junction design to effectively guard against reverse-polarity conditions, while its construction-grade materials make it suitable for use in extreme environments.
