MAPLAD36KP220AE3 TVS - Diode Application Field and Working Principle

MAPLAD36KP220AE3 TVS diodes are electrical components used in various types of electrical applications such as power supplies, electronic equipment, and power control systems. Generally, the TVS (Transient Voltage Suppressor) diode performs the same basic function as standard diodes, but with a added capability of suppressing transients or electrical pulses that are created through current surges, damaged insulation or a series of disconnects when two circuits create a current flow. In various applications, this added feature of transient suppression prevents a circuit from damaging itself or the equipment connected to it.

Application Fields

MAPLAD36KP220AE3 TVS diodes are one of the most commonly used electrical components when transient suppression is needed. Used in various power supplies as circuit protection, they also are widely used in Ethernet broadband systems, LCD and LED TVs, servers, and other various electronic systems to suppress the ESD (Electrostatic discharge) pulses, EFT (Electrical Fast Transient) surges, and differential-mode currents that are usually present in these types of circuits.

In addition, the MAPLAD36KP220AE3 TVS diode can be used for its clamping capability in many automotive applications, such as protecting the airbag system from accidental over-voltage, and suppression of differential mode current transients in car ECUs (Engine Control Unit). Furthermore, this particular diode is very popular for its easy of surface mounting as it requires no special tools, and is commonly used in device interfaces.

Working Principle

MAPLAD36KP220AE3 TVS diode functions as a normal silicon diode when there is no over-voltage transmitted through a circuit, which means it will act as an insulator for the current. However, if the voltage exceeds the reverse-biased breakdown value, the diode will become a closed switch and direct all currents into itself, thus funneling the voltage into its own body. This process is referred to as the “clamping process”.

For instance, when applying MAPLAD36KP220AE3 TVS diode to a power supply system, an over-voltage can cause a current flow surge. When this happens, the MAPLAD36KP220AE3 TVS diode will direct the extra power to itself in order to provide protection and prevent circuit damages. The MAPLAD36KP220AE3 TVS diode is then able to safely dissipate the power as heat, thus protecting the circuit from any damage.

Conclusion

The MAPLAD36KP220AE3 TVS diode is a transistor type component used to protect circuits from over-voltages or current surges. It can be used in applications such as power supplies, electronic equipment, and automotive systems where transient suppression is needed. The MAPLAD36KP220AE3 TVS diode works by acting as a “clamp”; absorbing currents to itself in order to prevent damages to the system and equipment connected to it. Overall, the MAPLAD36KP220AE3 TVS diode is an invaluable component in many circuits as it provides necessary protection against accidental over-voltages.
