TVS - Diodes, also known as Transient Voltage Suppressor Diodes, are protective components designed to protect circuits against voltage transients generated by electrostatic discharge (ESD), inductive switching, and other disturbances. This document will discuss the application field and working principles of MA5KP60CAE3—a typically used surface mount transient voltage suppressor diode.

MA5KP60CAE3 is a unidirectional device to suppress high-energy, positive transients greater than its break over voltage. It is commonly used in IEC61000-4-2, Level 4 ESD immunity testing (contact discharge) and in IEC61000-4-5, Surge Immunity testing. It is specifically designed for a variety of protection applications including automotive, industrial control systems, telecommunications, consumer electronics and many others. It provides excellent clamping performance with a low clamping voltage and fast response time.

The MA5KP60CAE3 can be installed in a variety of circuit topologies including SOT-23, SMA package and other packages. Generally, the SOT-23 package is the most common configuration used in most applications. Other packages can be used in higher temperature, higher humidity, and/or higher voltage applications.

The working principle of MA5KP60CAE3 is based on two functions. It contains a Zener diode which clamps sudden surge voltage to a specific level. When incoming voltage rises above the Zener breakover voltage (VBR), current will flows from the anode to the cathode. This process restricts surge current, allowing it to pass through the diode and be depleted by a current limiting resistor connected in series with the diode.

At the same time, another critical factor, which is the reverse working voltage, or the breakdown voltage (VBR), plays an important role in limiting the transient voltage. If the incoming voltage rises above the reverse working voltage, a reverse current will flow through the diode until the voltage is decreased below the VBR. The VBR of MA5KP60CAE3 is 6.0 volts.

In conclusion, the MA5KP60CAE3 is a surface mount transient voltage suppressor diode and can be used in various applications. It provides excellent clamping performance with low clamping voltage and fast response time, and can effectively protect circuits against voltage transients generated by Electrostatic Discharge (ESD), Inductive Switching and other disturbances. The working principle of MA5KP60CAE3 is based on two functions, the Zener diode and its reverse working voltage.
