The SMF85A RQG (Reverse Quarter Geometry) is an advanced TVS (Transient Voltage Suppressor) diode which provides superior protection for sensitive electronics from electrical transients. It is suitable for protecting a wide range of semiconductor devices, such as microcontrollers, shift registers, crystal oscillators, memories, and power devices, as well as providing a failsafe protection for applications subjected to ESD (electro-static discharge).

The SMF85A RQG is designed using NXP Semiconductor’s advanced reverse quarter geometry (RQG) technology which enables the device to provide a much faster response time in comparison to other transient voltage suppressor diodes; it is also able to withstand higher working voltages up to 9V, as well as providing lower leakage current than most other TVS diodes.

The working principle of the SMF85A RQG is based on the concept of avalanche breakdown, which is a phenomenon that occurs when an electric current in a reverse-biased semiconductor device exceeds the breakdown level. This causes an avalanche of electrons to flow from the P-type to the N-type region, resulting in a rapid increase in the voltage across the junction. The SMF85A RQG will then clamp the input voltage to its breakdown voltage, thus preventing further voltage spikes and providing protection against any transient voltages that might otherwise damage sensitive electronic components.

The SMF85A RQG has many advantages over other TVS diodes. It has an incredibly fast response time of less than 1ns, making it ideal for protecting sensitive electronic components, such as microcontrollers, from electrical transients. In addition, the device has a much higher breakdown voltage than regular TVS diodes, which makes it suitable for use in higher voltage applications. Furthermore, the SMF85A RQG has a low capacitance of just 4.5pF, which helps to reduce device power consumption and also prevents any interference from creeping into the protected circuit.

The SMF85A RQG has a wide range of application fields including consumer electronics, automotive, medical, industrial, and aerospace. It can be used to protect against electro-static discharge (ESD) in PCs, tablets, smartphones, and other electronic devices. The SMF85A RQG is also an ideal protection solution for power supply voltages, I/O ports, and many other applications.

In summary, the SMF85A RQG is an advanced transient voltage suppressor (TVS) diode suitable for a wide range of applications. It utilizes NXP Semiconductor’s reverse quarter geometry (RQG) technology to provide superior protection from electrical transients and ESD, with its incredibly fast response time and high breakdown voltage. Furthermore, its low capacitance ensures minimum power consumption and less interference, making the SMF85A RQG an excellent choice for any application needing reliable protection.
