TVS (Transient Voltage Suppressors) Diodes are designed to protect sensitive electronic equipment from voltage transients caused by events such as lightning strikes, electrostatic discharges, power line surges, or inductive switching. Among them, MPLAD36KP20CAE3 is specifically developed to protect low-voltage microcontroller (MCU) and other applications that are sensitive to EMI (electromagnetic interference) and for which ultra-low capacitance sub-1pF is required in an ultra-small SOT323 package. This article will discuss the applications and working principle of MPLAD36KP20CAE3.

MPLAD36KP20CAE3 is most suitable for electrical board design applications which require an uni-directional ESD protection device with ultra-low capacitance values. The standard ESD protection for I/O pins of MCUs are spikes in air-gap between finger and the pad of the device. The MCUs are especially vulnerable to this type of transients. To prevent this from happening, MPLAD36KP20CAE3 is used. The device is ultra-low capacitance at 0.75pF and is mounted in a SOT323 package.

MPLAD36KP20CAE3 is in a uni-directional ESD device with a high workingvoltage of 20V that allows it to power the device under heavy surge conditions. The device can discharge the high ESD pulse with high speed and efficiency. The device can handle high ESD pulse of up to ±17KV contact discharge, with a clamping voltage of 36V. The device offers excellent ESD performance while maintaining low operating capacitance, ensuring that the MCU has no significant interference from electromagnetic rays.

The working principle of MPLAD36KP20CAE3 is based on the principle of charge balance. In this case, the device including a single element core and a surface-mounted ESD diode. When exposed to an electrostatic field, the device disperses the field over a larger area of the device and spreads the field current over a larger volume of the device than a conventional diode. This results in a lower overall voltage drop across the device compared to a standard diode. This is how the device offers ultra-low capacitance of 0.75 pF while being able to handle a high ESD pulse.

MPLAD36KP20CAE3 is an ideal choice for applications which require good on-board ESD protection. It offers high performance, owing to its excellent ESD performance and low operating capacitance. It can power the device under heavy surge conditions, while ensuring efficient and reliable operation. The device can handle a high ESD pulse of up to ±17KV contact discharge, with a clamping voltage of 36V. It is recommended for applications which require an ultra-low capacitance value and uni-directional ESD protection device.
