MSMBJ85AE3

TVS (Transient Voltage Suppressor) diodes are one of the most important components in electrostatic discharge and electrical transient protection. Generally, TVS diodes are categorized as solutions for protecting against over-voltage and over-current surges. The MSMBJ85AE3 is a bi-directional, unidirectional, and bidirectional TVS diode from the semiconductor company ON Semiconductor. The device is designed to protect electrostatic discharge, surges, transients, and electrical over-voltage in a variety of applications, including automotive, consumer electronics, and high-tech signal and data transmission systems. MSMBJ85AE3 is available in both SOT-323 and SC-70 packages.

The MSMBJ85AE3 TVS diode consists of a PN junction diode configured in a two-pin package. It is designed to clamp high peak transient voltages and dissipate large Peak Pulse powers. The device is a monolithic, bidirectional, symmetrical, unidirectional, or dual common-cathode TVS constructed of silicon avalanche rectifiers. It has a maximum breakdown voltage of 85V and a maximum peak pulse power rating of 600W.

The MSMBJ85AE3 TVS diode operates in a very simple fashion. When it comes into contact with an over-voltage surge, it will act as a non-linear voltage-limiting device to protect the connected circuit. The diode will draw a low current from the surge voltage to protect the circuit. Once the voltage returns to the normal operating range, the diode will quickly reset itself and be ready to protect the circuit against future surges.

The design of the MSMBJ85AE3 TVS diode provides it with several key advantages. It has a very fast response time, allowing it to respond to transients quickly and accurately. Additionally, the diode has a very low clamping voltage, allowing it to absorb energy from the surge without adversely affecting the circuit\'s normal operation. It also has a low dynamic resistance, meaning that it can absorb large amounts of energy and dissipate the energy safely. Lastly, the MSMBJ85AE3 TVS diode is relatively inexpensive and can be used in a wide variety of applications.

The MSMBJ85AE3 TVS diode is commonly used in automotive applications, consumer products, and high-tech signal and data transmission systems. In automotive applications, the diode is used to protect circuits that may be affected by over-voltage, surges, electrical transients, and electrostatic discharge. This can include boosting the car\'s radio reception, preventing short circuits, and protecting vulnerable components from damage. Consumer products commonly use the diode for over-voltage protection, surge protection, and transient protection, as well as protecting against electrostatic discharge.

Lastly, MSMBJ85AE3 TVS diodes are used in high-tech signal and data transmission systems. In such systems, the diode acts as a non-linear voltage limiter, clamping high-frequency transients and preventing them from adversely affecting sensitive components. The diode also acts as a low-pass filter, removing any undesired high-frequency components.

In summary, the MSMBJ85AE3 is a bi-directional, unidirectional, and bidirectional TVS diode from the semiconductor company ON Semiconductor. It is designed to clamp high peak transient voltages and dissipate large Peak Pulse powers, while providing excellent protection against over-voltage, surges, electrical transients, and electrostatic discharge. It is commonly used in automotive, consumer, and communications applications, where it is able to provide effective protection and performance.
