TVS - diodes is an important component in electric circuit protection, and LCE85A is a kind of popular TVS devices from Littelfuse. As an important protector, the application fields and working principle of LCE85A TVS-diode should be understood.

In terms of application fields of LCE85A, it can be used in automotive, industrial electronics, consumer MSR and telecom infrastructure. Apart from these applications, it can be used in different and versatile applications that require surge protection. LCE85A series TVS-diodes offer up to 560W peak pulse power, 4kV ± 6kV surge for an 8/20μs waveform, ultra-fast response time as low as 1 nanosecond, ultra-small package, and pPPM standard dissipation. This make LCE85A TVS-diodes popular in many applications that require excellent protection.

To understand how LCE85A TVS-diodes perform, let us take a look at its working principle. LCE85A TVS-diodes act like a simple diode in the normal state, which only allows current flow in one direction. When surge voltage occurs, it will be clamped down to a fixed value and grounded, thus providing protection and minimising the chance of damaging the circuit or devices. Under an intense surge event, LCE85A TVS-diodes can conduct an amount of surge current and safely divert it to the ground, thus ensuring the safety of the electric circuit and devices in the circuit.

Apart from its excellent surge protection ability, LCE85A also has some other advantages. Typically the junction capacitance of the LCE85A TVS-diode is relatively small, which means it has low parasitic capacitance for the signal lines in the transmission line. This helps to minimise the electrical noise interference and has some important implications in the analog application.

To sum up, LCE85A TVS-diodes are a kind of popular surge protector, and they have a wide range of applications in electric circuits. Also, their working principle and advantages should be noted.
