Transient Voltage Suppression diodes, more commonly referred to as TVS diodes, are an important component of any power supply design. The MXLP5KE78A TVS diode is a high performance device designed for the protection of power supply circuits against voltage transients.

The MXLP5KE78A is a single-line TVS diode in a low-profile, surface mount, 5.1mm, thermally-enhanced package and is rated at 78V. It is designed to provide protection against transients such as lighting, inductive switching, and automotive ignition. When exposed to a voltage higher than the device’s nominal rating, the diode will clamp the transient voltage, thus preventing it from damaging the circuit or the connected device.

The MXLP5KE78A diode has an impressive peak pulse power rating of 9kW, as well as a response time of less than 1ns (nanosecond). The device also features a rated leakage current of 1µA maximum, which helps prevent drain corrosion for higher reliability.

In terms of its application field, the MXLP5KE78A diode is ideal for protection of power supplies that are exposed to high power levels. It is suitable for use in a wide variety of applications including power supplies for consumer electronics, industrial control systems, automotive systems, as well as renewable energy sources.

In terms of its working principle, the MXLP5KE78A is a nonlinear device that operates in the avalanche breakdown region of the diode’s I-V curve. When the diode is exposed to a voltage higher than its specified breakdown voltage, the electric field within the device increases to a point where the diode begins to conduct current, producing a clamping action that protects the circuit and connected components against transient voltage.

The MXLP5KE78A is designed to provide protection against transients that exceed its specified breakdown voltage, allowing the device to provide effective protection against power supply transients. The device’s impressive peak pulse power rating, response time, and low leakage current make it an excellent choice for high power applications.
