TVS - Diodes: TGL41-30-E3/96 application field and working principle

Transient Voltage Suppression (TVS) diodes, also known as a ‘stabilizer’, are specialized semiconductor devices used to protect sensitive electronic components from damage caused by transient voltage spikes. Transient voltages are short duration voltage spikes that occur too rapidly for traditional overvoltage protection devices to react.Such spikes can occur during electromagnetic events such as electrical transmission power switching, lightning strikes, and static discharge.

The TGL41-30-E3/96 is a uniquely designed, highly reliable 3-Line TVS device designed to protect against high-energy transients caused by inductive and capacitive loads. This device is typically used in applications such as fuse and breaker protection, as well as other communications and control systems that may require additional transient voltage protection.

Working Principle

TVS diodes usually come in two forms: Zener and Transzorb diodes. The TGL41-30-E3/96 utilizes the Transzorb diode for its working principle. It works by having a very fast switching action which enables it to quickly dissipate the energy caused by a transient voltage before it can damage the protected device. Transient voltage is usually generated by a sudden change in the voltage level – this could be caused by a power surge or lightning strike. The diode will then rapidly ‘breakdown’ the voltage, converting it into heat which is absorbed and dissipated into the environment.

Application Field

As mentioned above, the TGL41-30-E3/96 is particularly effective in protecting against high-energy transients caused by inductive and capacitive loads. This diode is particularly well suited for use in motor circuit applications, such as circuit breaker or fuse protection. This is due to the TGL41-30-E3/96’s ability to efficiently and quickly dissipate transient voltage while also providing overvoltage protection.

The TGL41-30-E3/96 is also suitable for use in a variety of communication and control systems that might require additional transient voltage protection. This diode is particularly useful if there is a risk of an external transient voltage event occurring – such as a power surge or lightning strike.

In conclusion, the TGL41-30-E3/96 is a highly reliable TVS diode that is well suited for use in motor circuit applications, as well as in a variety of communication and control systems that require additional transient voltage protection. Its unique design allows it to quickly and efficiently dissipate transient voltage, thus providing protection to the protected device.
