TVS (transient voltage suppressor) diodes are designed to provide high electrical protection against transient over-voltage events. This article will explore the application field and working principle of the MSMCJLCE75A TVS diode.

Applications

The MSMCJLCE75A TVS diode is a unidirectional diode that is designed to provide surge protection from over-voltages on I/O lines. It can be used in a wide variety of applications such as transient protection of data lines, power lines, telecom lines, and consumer electronic equipment. MSMCJLCE75A TVS diodes are also suitable for protecting signal lines from surge-induced damages.

Working Principle

When excessively high voltages, caused by lightning or electrostatic discharge (ESD) for example, appear on the protected line, the TVS diode breaks down rapidly by a “snap-off” process. This occurs when the diode’s reverse breakdown voltage (clamping voltage) is exceeded, allowing a high current to flow through the diode.

The MSMCJLCE75A has a clamping voltage of 75V and is designed to dissipate 360W of energy at 8/20μs in a 10/1000μs waveform. This allows it to absorb large pulse energy without heat accumulation and makes it suitable for use in surge protection.

Summary

The MSMCJLCE75A is a TVS diode used to protect sensitive electronic components from short duration, high-voltage transient events. It has a clamping voltage of 75V and is designed to dissipate 360W of energy at 8/20μs in a 10/1000μs waveform. These features make the MSMCJLCE75A suitable for use in a variety of applications, including transient protection of data lines, power lines, telecom lines, and consumer electronic equipment.
