Transient Voltage Suppressors (results: 1673)

Protective Diodes (Transil)

Protective diodes are specialized electronic components designed to safeguard circuits from overvoltage and transient disturbances. Their role is to quickly limit excessive voltage caused by lightning strikes, switching operations in installations, or other sudden changes in the power supply network.

Operating Principle of Protective Diodes (Transil): Overvoltage and Transient Disturbance Protection

Transils act as surge protection devices. When the voltage exceeds a specified threshold, they rapidly switch to a conducting state, diverting the surge energy and protecting sensitive components from damage. Due to their fast and effective response, transils are essential in modern electronic systems.

Electrical Parameters of Protective Diodes: Breakdown Voltage, Surge Energy, and Response Time

When selecting protective diodes (transils), their electrical parameters are crucial in determining the effectiveness of protection. Key parameters include:

• breakdown voltage – the voltage at which the diode suddenly becomes conductive, diverting excess energy.

• surge energy (Ws) – the maximum energy the diode can absorb during a short overvoltage impulse.

• response time – transils are characterized by very fast reaction times, which are essential for effective protection of delicate electronic circuits.

Understanding these parameters will help you select protective diodes perfectly matched to your specific application. Such suitable diodes are available in the Micros product range.

Application of Transil Diodes in Overvoltage Protection Systems for Electronic Circuits

Protective diodes have wide application across many electronics fields where effective overvoltage protection is required. They are used in:

• power supplies and power systems,

• telecommunication systems,

• industrial automation,

• consumer electronics.

By using transil diodes, you can significantly extend the lifespan of your devices and increase their reliability. This is especially important in professional and demanding applications.

Comparison of Transil Diodes with Other Protective Solutions: Advantages and Limitations

Among the available overvoltage protection solutions, transil diodes stand out due to:

• very fast response time,

• precisely defined breakdown voltage,

• resistance to multiple surge pulses,

• compact size and ease of mounting.

Their limitations include reduced effectiveness at very high surge energies and lower performance under overload conditions.

Selecting the Right Transil Diode: Choosing Based on Voltage, Surge Energy, and Application

Selecting the appropriate transil diode should be based on a thorough analysis of the application requirements and the parameters of the device to be protected. Pay attention to:

• operating voltage and breakdown voltage,

• maximum surge energy,

• mounting conditions and package type,

• specifics of the application.
