TVS (transient voltage suppressor) diodes are part of the family of voltage protection devices commonly used in many electronic systems to protect them from high voltages and large current transients. The SMP16-M3/84A TVS diode is an advanced version of the SMF series of voltage suppressor diodes that offers superior performance and reliability in harsh and rugged application environments. The diode is made up of a rugged ceramic package and is designed for top-powered over-voltage protection.

Application Field

The SMP16-M3/84A is designed for automotive, aerospace, military, and other harsh environments that are exposed to high temperatures, vibration, or shock. It can also be used in consumer electronic applications such as notebook and desktop computers, PDAs, and digital cameras. In addition, it can be incorporated into circuit boards for industrial, telecom, and medical applications.

The diode is especially well-suited for environments with high humidity, moisture, or dust as well as high-voltage/high-temperature applications. It is also suited for use in high-voltage electric power grids and military applications. Furthermore, the diode is suitable for use in a variety of power supply designs including isolated and non-isolated topologies.

Working Principle

When a voltage higher than what the SMP16-M3/84A is designed to withstand is applied to it, the diode will activate its protection circuit. This protection circuit will then force the diode to enter into its avalanche breakdown state, allowing a large current to flow through it to bypass the external voltage source and protect the circuit from overvoltage. Once the transient event is over, the diode will return to its original, non-conducting state. In this manner, the diode acts as a one-way valve, allowing current to flow in one direction only and preventing damaging spikes of current from passing through the circuit.

The diode\'s protection circuit is designed to be virtually instantaneous, allowing it to respond to transients as quickly as possible and neutralize them while they are still below the voltage level required to damage the circuit. The diode also features a wide operating temperature range, so that it can remain active even when subjected to extreme heat or cold.

The SMP16-M3/84A is an example of a TVS diode that has been designed to provide superior protection to high-voltage and high-current circuits in tough, hostile environments. By leveraging its state of the art protection circuitry and rugged construction, the diode can provide long-lasting protection to even the most extreme operational environments.
