TVS - Diodes: MXLP4KE100AE3 application field and working principle

The MXLP4KE100AE3 is a transient voltage suppression (TVS) diode, which is available in an ultra small SOT-323 package. It is designed to protect sensitive electronic equipment and devices from voltage spikes caused by transients, static electricity discharges, power surges, etc. The MXLP4KE100AE3 can be used for board level protection in consumer electronics, automotive and telecommunication equipment and networks.

The MXLP4KE100AE3 is a mono-directional diode that can suppress voltage peaks. It has a peak pulse power rating of 400 Watts (pk) and a peak pulse current of 10 Amps (pk). It has a low operating clamping voltage of 6.5V typically at 125A. The device is characterized for operation from -55°C to +150°C.

The MXLP4KE100AE3 works by suppressing voltage spikes and current surges using a specially designed diode. The diode is designed to protect sensitive electronic components from damage resulting from voltage spikes. The MXLP4KE100AE3 functions as a zener diode, clamping the voltage across its terminals when it exceeds its breakdown voltage. This voltage clamping is known as "breakdown voltage". When the voltage on the diode is higher than the breakdown voltage, the diode will conduct current (limited by its max rated current) and ‘clamp’ the voltage to its rated breakdown voltage, thus protecting the components connected from high voltage transients.

The MXLP4KE100AE3 has a maximum peak pulse power of 400W and a maximum peak pulse current of 10A. The breakdown clamping voltage is typically 6.5V, with a low maximum clamping voltage of 9V. The device is designed to operate over a wide temperature range from -55°C to +150°C, making it ideal for use in automotive, telecommunications and other harsh environments. The device is available in a small SOT-323 package, making it suitable for use in space constrained applications.

The MXLP4KE100AE3 uses a metal-oxide varistor to protect against voltage spikes. This technology works by providing a high impedance path through which the transient current and voltage can pass, allowing the transient to dissipate safely and without damaging the protected components.

In summary, the MXLP4KE100AE3 is a TVS diode designed to protect sensitive electronic components from voltage spikes, transients and other high voltage surges. It has a peak pulse power rating of 400W and a peak pulse current rating of 10A. It operates over a wide temperature range and is available in a small SOT-323 package. The device uses metal-oxide varistor technology to provide a high impedance path for the transient current and voltage, allowing it to safely dissipate without causing any damage.
