TVS (Transient Voltage Suppressor) diodes are often used in protection circuits for protecting sensitive electronic equipment. The MSX1PBHM3/89A is the latest type of diode developed for this purpose. It is composed of two discrete diodes connected in series and is also referred to as a double diode. It is designed to absorb transient voltages up to 20kV and has a surge current rating of 1.25A.

The main application field for the MSX1PBHM3/89A is in the high frequency, RF protection circuits of consumer electronics. It is used in this application mainly because of its high surge current rating, which is critical for RF protection. It is also suitable for use as a transient voltage suppression (TVS) diode in industrial and automotive applications.

The MSX1PBHM3/89A also has a surge absorption capacity that is superior to traditional avalanche diodes. It uses a specially designed silicon-oxide layer to limit the spread of electron-hole pairs, which helps to reduce the amount of transient energy that it can absorb. This makes it well suited for use in protection circuits in which exposure to large transients, or surges in voltage, are frequent.

The working principle of the MSX1PBHM3/89A is based on the same principles that govern the behavior of other TVS diodes. When the applied voltage reaches a certain threshold, the diode begins to conduct current. The diode then acts as a shunt, dissipating the energy of the transient by producing a short circuit effect, effectively absorbing the excess voltage and protecting the sensitive electronic components from damage. This type of diode is particularly well suited for its application in RF protection circuits, as its low capacitance and small footprint make it ideal for high frequency protection.

In conclusion, the MSX1PBHM3/89A is a unique type of diode which is used in high frequency, RF protection circuits of consumer electronics. It is designed to absorb transient voltages up to 20kV and has a surge current rating of 1.25A. It has a superior surge absorption capacity than traditional avalanche diodes and utilizes a specially designed silicon-oxide layer to limit the spread of electron-hole pairs. Its working principle is based on the same principles that govern the behavior of other TVS diodes. The MSX1PBHM3/89A is ideal for high frequency protection and is suitable for use as a transient voltage suppression diode in industrial and automotive applications.
