The SMBJ6.5 is one of the few TVS – Diode types that can be used with low-voltage systems. It\'s a surface-mounted device (SMD), which makes it ideal for uses in any conditions where low-voltage applications are needed. The SMBJ6.5 is typically used to protect sensitive electronics from overvoltage transients. It can be used to protect microcontrollers, operational amplifiers, and other low-voltage electronic devices.

The SMBJ6.5 is a unpolarized device, meaning it can be connected either way. This makes it extremely versatile, as there is no restriction on the orientation of the TVS – Diode. However, the SMBJ6.5 does have an additional feature that other TVS – Diodes don’t. The SMBJ6.5 also has an adjustable threshold voltage (Vi) that can be set to meet the needs of the application or the specific requirements of the device it’s protecting. This feature makes it invaluable for any application where sensitive equipment or circuits must be protected from high-power, high-voltage transients.

As with all TVS – Diodes, the SMBJ6.5 is a clamping device, meaning it limits the voltage that is applied to a device. When an excessive voltage is applied, the SMBJ6.5 diverts the transient current round a low-impedance path away from the device, thus protecting it. The SMBJ6.5 is a low-capacitance device, meaning it doesn’t significantly interfere with the normal functioning of the device it’s protecting. This is important, as TVS – Diodes that introduce significant capacitance often degrade the performance of the devices they’re protecting, ultimately defeating the purpose of having them.

The working principle of SMBJ6.5 is quite simple. When the voltage applied to a device is higher than the adjustable threshold voltage (Vi) of the SMBJ6.5, the device will activate, creating a low-impedance path to divert the transient current away from the device, thus protecting it. This low-impedance path prevents the device from becoming damaged or destroyed due to the excessive voltage.

The SMBJ6.5 is very popular for use in low-voltage systems due to its adjustable threshold voltage (Vi), its large temperature range, and its low capacitance. The SMBJ6.5 provides robust protection for sensitive low-voltage devices that may be exposed to high-power transients. It’s an invaluable device for any low-voltage application that needs to be safely protected from high-voltage transients.
