MSMBJ85A/TR

TVS (Transient Voltage Suppressors) diodes, also known as clamp diodes, are electronic devices that protect connected components from voltage transients. The MSMBJ85A/TR is a bi-directional TVS diode that is typically used in automotive ESD applications. This help sheet will discuss the application field of this diode and its working principle.

The MSMBJ85A/TR diode can be used in automotive applications such as airbag and brake systems. It is designed to protect connected devices and drivers from ESD (electrostatic discharge) events up to +/-8 kV (HBM, Human Body Model). The diode is capable of safely dissipating up to 24.5 A of surge current. It also has a low reverse leakage current at high working voltage, making it suitable for low-noise operation.

The working principle of the MSMBJ85A/TR diode can be explained in terms of how it operates during an ESD event. When an ESD event occurs, the diode creates a low-impedance path to ground. This low-impedance path will quickly transfer any surge voltage and dissipate any high current caused by the ESD event. When the ESD event is over, the diode will reset and return to its normal operating mode.

The MSMBJ85A/TR diode is a reliable and efficient solution for automotive ESD protection. It is capable of withstanding high surge currents and dissipating the energy quickly and safely. The diode also has a low reverse leakage current at high working voltage, making it suitable for low-noise operation. As a result, it is well suited for automotive applications such as airbag and brake systems.
