MP5KE9.0AE3 Datasheet/PDFTVS - Diodes
TVS (transient voltage suppression) diodes are a type of semiconductor device whose ability to protect electronic circuits against voltages spikes. TVS Diodes come in a variety of forms and styles and provide protection against various electronic threats such as electrostatic discharge (ESD), inductive load switching, lightning, over-temperature, and power line surges. TVS Diodes protect circuits against high transient voltage surges in the 1µs to 1ms range by diverting the excess current during a surge and then removing the resulting voltage by clamping.
MP5KE9.0AE3 Application Field and Working Principle
The MP5KE9.0AE3 is a Transient Voltage Suppression Diode designed to protect sensitive electronic circuits from transient over-voltages. It is available in a small SOT-23 surface mount package. The diode can withstand voltages up to 9 V, has a low capacitance of around 14 pF, and is ideal for suppressing induced ESD transients Events up to 24A (8/20µs). The diode shows typical reverse leakage current down to 60nA, and very tight dynamic resistance across a wide range of voltages.
The working principle of the diode is fairly simple. When a voltage surge occurs, the diode activates and the current flows through it to the ground, thus diverting excess voltage away from the protected device. The diode can then clamp the voltage to about 9 V and keep it from getting too high. The diode then quickly returns to its original state after the voltage surge has passed.
The diode can be used in a variety of applications, such as ESD and over-voltage protection for computer and telecommunications systems, suppressing high current transients in automotive applications, and high-frequency PFET and LED protection for consumer electronics. The MP5KE9.0AE3 is reliable and provides reliable protection against high-voltage surges.
In summary, the MP5KE9.0AE3 is a reliable transient voltage suppression diode that provides low capacitance, low reverse leakage current, high peak current handling capability, and tight dynamic resistance. The diode is useful in a wide range of applications in automotive, consumer electronics, and other fields.
