The SM712 TVS Diode Array is intended to safeguard RS-485 applications with asymmetrical working voltages (-7V to 12V) from harm caused by surges from lightning, rapid electrical transients, and electrostatic discharge (ESD). The SM712 can withstand repeated ESD hits above the maximum level allowed by the international standard IEC 61000-4-2 while operating at extremely low clamping voltages, safely dissipating up to 19A of 8/20us induced surge current (IEC-61000-4-5 2nd edition).

Integral circuits are safeguarded using transient voltage suppressor diodes or TVS diodes (ICs). TVS diodes shield semiconductors and other delicate parts from large transient voltage spikes and the effects of arcs, inductive load switching, even lightning strikes, EFT, and ESD. TVS diodes are available from various manufacturers at RS, including Bourns, STMicroelectronics, Littelfuse, ON Semiconductor, Vishay, Taiwan Semiconductor, and more.
Bidirectional or unidirectional TVS diodes are available in through-hole and surface-mount packages. Bidirectional TVS diodes can operate at both positive and negative voltages, in contrast to unidirectional TVS diodes. Due to the design of its diodes, TVS diodes can conduct substantial currents to the ground. They have a significantly larger p-n junction cross-sectional area than conventional diodes.
Transient voltage suppressors clamp transient voltages almost instantly in response to overvoltage situations. This makes it possible for them to defend against the effects of inductive load switching, arcing, EFT (fast electrical transients), lightning strikes, and the ESD (electrostatic discharge) produced by data lines and electronic circuits.
When selecting a TVS diode, several differentiators exist, but reverse standoff and breakdown voltage are the two most important. The operational Voltage, the data or power line, should not exceed is reverse standoff voltage. The voltage rating, known as the breakdown voltage, is the point at which the TVS diode begins to protect the system and conduct electricity to the ground. The reverse standoff voltage is typically a little greater than this voltage value.
There are numerous TVS diodes, each with unique qualities and suitable for various circuits and applications.
There are surface-mounted and through-hole varieties available. Additionally, these parts can be unidirectional or bidirectional, giving you more freedom to select the TVS diode type that is ideal for your configuration.
Below are more details on a few of the primary TVS diode types:
One of the more well-known TVS types is the Zener diode. These parts have a lower breakdown voltage (called the Zener voltage), which enables them to perform controlled breakdowns by maintaining a close relationship between the Zener voltage and the current flowing across the diode. Additionally, they can be employed to create voltage references and provide circuit protection against overvoltage and ESD occurrences.
High-speed data lines and high-frequency circuits both benefit significantly from Zener diodes. They are frequently used for diverting and clamping in these circuits due to their restriction to handling low energy.
TVS diodes are used in the automotive industry to shield delicate parts and semiconductors from harm from transient spikes and discharges. To provide protection, they can be used in various locations inside vehicles, including close to the alternator and regulator (which guards against high-energy events like field decay or load dump) and electronic data buses (which guard against ESD events), to name a few.
Negative and positive voltages are both compatible with bidirectional diodes. As a result, they are more adaptable than unidirectional diodes, which can only function with either positive or negative voltages.
It is important to remember that other varieties of TVS diodes can also be bidirectional. For instance, because Zener diodes are bidirectional, they are better equipped to handle circuit fluctuating voltages.
Another common form of the diode is a clamping voltage diode. Typically, this word refers to clamps that shield delicate electronics from transients and overvoltages.
These high Voltages can be effectively handled by specialized clamping diodes, which can clamp the residual Voltage and divert the surplus. Additionally, TVS clamping diodes can safeguard circuits and parts that are exceptionally delicate, responding to transients significantly faster than alternatives to lessen the risk of damage.
Selecting the appropriate device is crucial to ensure ESD protection because not all diodes are ESD-sensitive. ESD diodes should be positioned on the trace in proximity to the ground.
ICs are protected against high-Voltage ESD incidents using ESD protection diodes. To provide protection and stop circuits from malfunctioning, they absorb aberrant Voltage. The device malfunctions in an ESD event, creating a low-impedance path that restricts and directs the current flow to the ground, thereby securing the circuit.
Components used to suppress transient voltages, such as ESD events, include transient suppression diodes.
They protect against spikes that could damage circuits and fragile components by grounding the clamped Voltage. The circuits and applications that require these fast-acting, straightforward unidirectional, and bidirectional devices have intermediate frequency ranges. Transient suppression diodes can be more expensive than alternative solutions and have a limited frequency due to their large capacitance.
