TVS – Diodes: MA5KP6.5AE3 application field and working principle

Transient voltage suppression diodes, or TVS diodes, are components that are electrically designed to handle and protect other components from transient voltages (within its own rating), which could potentially damage other components. The transient voltage must exceed the devices working voltage before it activates. Famous examples of devices using TVS diodes include power supplies, computers, and circuit boards.

The MA5KP6.5AE3 is an example of a TVS diode. It is a unidirectional diode designed to safely absorb and manage transient over-voltage occurrences. This component comes in a SOT-23 package. It features a Breakdown Voltage of 6.5V for 5KW (5.0KW over voltage), 220 nsecs maximum clamping voltage, low capacitance, and ESD protection, to name a few.

The application field of the MA5KP6.5AE3 is broad, and can encapsulate a variety of scenarios. One major usage of this device is on computer peripheral boards, especially when it comes into contact with lightning or other over-voltage sources. It is also suitable for automotive applications, such as airbags and ignition systems.

The working principle behind the MA5KP6.5AE3 TVS diode is relatively straightforward. It functions by introducing a short low impedance current path for any voltage spike that occurs, allowing components connected to it, or an entire system, to remain protected. This short and available current path blocks the surge, and dissipates it into a 1-ohm resistor, of which it should fall below the peak surge energy in the system.

Conclusion: The MA5KP6.5AE3 is a powerful TVS diode that can be effectively used to protect computer peripherals, automotive components, and entire systems from transient over-voltages. It features a 6.5V breakdown voltage, ESD protection, and an available short current path to intercept and dissipate any surge.
