USB50812CE3/TR7 Circuit Protection

TVSs (Transient Voltage Suppressors) are essential components which protect sensitive electronics from overvoltage disturbances and electrical transients. Silicon diodes (TVS-Diodes) provide protection against voltage spikes with excellent transient overvoltage protection performance. USB50812CE3/TR7 is a typical type of TVS-Diodes. It is designed to protect sensitive electronics from over-voltage, damage and destruction by the lightning strike and inductive kick-back of high-energy transient.

The package of USB50812CE3/TR7 is in a SOT-323 package, with an operating temperature range of -55℃ to 150℃. The maximum peak pulse power dissipation and breakdown voltage arestanding at 600W and 41.3V, respectively. It also features an opposite polarity device (E Series diode), which minimized the capacitive loading and provides protection against positive and negative electrical transients.

Applications of USB50812CE3/TR7

USB50812CE3/TR7 is widely used in hand held devices, PC boards, telecom boards, digital home applications, industrial controllers, and consumer electronic systems. It can also be used on automotive electronics, motherboard, server and routers, or any other devices that require protection from over voltage.

Working Principle of USB50812CE3/TR7

The working principle of USB50812CE3/TR7 is similar to a diode. It can absorb any surge or spike in the voltage and limit the peak voltage, thus protecting the connected components from over-voltage damage. This type of protective diode normally has a junction breakdown voltage of 41.3V. When the reverse voltage across the diode is below this threshold, the diode will remain in the off/open state; but when the reverse voltage exceeds 41.3V, the diode will break down and enter into the on/closed state, thus providing protection to the connected components.

Besides, this type of diode also provides the function of clamping. If the applied voltage exceeds the breakdown voltage, the diode will short circuit the incoming voltage, thus limiting the voltage to a safe level and providing protection to the connected components.

In conclusion, the USB50812CE3/TR7 is a type of TVS-Diodes, which is designed to protect sensitive electronics from over-voltage due to lightning strike, inductive kick-back or spike. It Has a maximum peak pulse power dissipation of 600W along with a breakdown voltage of 41.3V, and a broad range of applications. Its working principle is similar to a diode, with the ability to limit the peak voltage and provide protection via its short circuit clamping function.
