TVS (Transient Voltage Suppressor) diodes can prevent the unwanted transients that working circuits see from time to time. TVS diodes are available in a variety of shapes and sizes, which make them suitable for protecting small electronics to large factories and data centers. The MXL5KP26A is a prime example of one such TVS diode. This article will discuss the application field and working principle of the MXL5KP26A.

Application Field:

The MXL5KP26A is a 5.2V bidirectional diode with a peak pulse power rating of 5.7KW or 26A. This diode is typically used in automotive, consumer electronics, and computer equipment to protect against over-voltage transients. It is also found in applications that require high pulse capability. This device is also used to protect sensitive components such as analog-to-digital converters, voltage regulators, and microcontrollers.

Working Principle:

The working principle of the MXL5KP26A lies in its ability to provide surge protection while effectively clamping any transients over the specified voltage level. This device has two distinct components consisting of a metal-oxide-semiconductor field-effect transistor (MOSFET) and a diode that are designed to activate in the same manner as valve controlled devices used in consumer electronics. The drain-to-source voltage of the MOSFET is used to turn on the TVS diode, and the MOSFET also serves as a current limiter to prevent the TVS diode from drawing too much current.

The working process of the MXL5KP26A can be broken into two stages. In the first stage, when a low-voltage transient is experienced, the MOSFET will be turned on allowing the diode to conduct current. The amount of current conducted will depend on the load across the diode. In the second stage, when the voltage across the diode exceeds the specified breakdown voltage of the diode, the diode is short-circuited, thus preventing any further damage.

Conclusion:

The MXL5KP26A is an excellent choice for protecting sensitive circuitry from over-voltage transients. This TVS diode has a working principle that consists of two components: a MOSFET and a diode. Its high peak-pulse power rating and low breakdown voltage make it an excellent choice for applications that require high pulse accuracy and durability. The MXL5KP26A is an ideal choice for protecting automotive, consumer electronics, and computer equipment against over-voltage transients.
