TVS – Diodes

Transient Voltage Suppression, or TVS diodes, are essential semiconductor circuit protection devices. They can protect sensitive electronic components within a circuit from external transients resulting from lightning strikes, or other transient events. The PGSMAJ8.5A M2G is an example of a transient protection device, with various application fields and a working principle that make it particularly suitable for sensitive circuits.In many circuits, transient events can cause excessively large voltages, or overvoltages, to form within sensitive circuit components. These overvoltages can cause extremely high power losses, reducing circuit performance and leading to potentially expensive repairs. TVS diodes are designed to protect such circuits from overvoltages, by absorbing transient event voltages in an orderly manner. When a transient occurs, the TVS diode will absorb most of the voltage spike and thus protect the circuit components from being damaged.The PGSMAJ8.5A M2G is a surface mount TVS diode featuring high levels of surge current protection. It is specially designed to protect sensitive circuits from transients resulting from ESD events, or Electro Static Discharge. It has a clamping voltage of 8.5V at 8A, and is available with European E10 ratings. The device also has a very fast response time, allowing it to protect the circuit from repeated ESD events.The PGSMAJ8.5A M2G has excellent directivity, impedance suppression and peak energy handling capabilities. The peak energy of the diode is maintained over a wide range of clamping voltages, and its low capacitance allows it to be used in a wide range of sensitive applications. The device is also offered with various electrical parameters, allowing the user to choose the best possible combination for any given circuit.The PGSMAJ8.5A M2G has a number of applications fields, including consumer electronics, medical systems, automotive equipment and telecommunication systems. It can be used to provide lightning protection, overvoltage protection, overcurrent protection and ESD protection. In addition, the device can be used in various combinations with other components, in order to optimise the protection of any sensitive digital or analogue circuit.The working principle of the PGSMAJ8.5A M2G is based on the principle of zener breakdown. When a transient exceeds the zener voltage of the device, a current flows through the PN junction of the diode, resulting in a change of voltage across the device. The excess voltage is clamped at 8.5V, preventing it from damaging sensitive components in the circuit. The device then quickly dissipates the transient surge energy, allowing the circuit to recover.In summary, the PGSMAJ8.5A M2G is a transient voltage protection device with excellent surge current protection and fast response time. It has a number of applications fields, and can be used to protect a range of sensitive circuits from transient events. The device works on the principle of zener breakdown, absorbing the excess voltage of a transient event and quickly dissipating it, preventing damage to delicate components.
