TVS (transient voltage suppressor) diodes have become increasingly popular in recent years. This is due to their ability to protect a device or system from high-voltage transients, as well as other environmental stressors such as electrostatic discharges and surges. The RSB6.8SMT2N is an ultra-low capacitance, surface mount TVS diode with an ultra-small SMT package. It is designed for applications where space is limited and transient protection is needed. In this article, we will discuss the application field and working principle of the RSB6.8SMT2N.

The RSB6.8SMT2N is primarily used in automotive applications, including automotive electronic control units (ECUs) and ECM microcontrollers. In situations where the ECU or ECM are exposed to severe electrical transients and surges, a low capacitance TVS diode can provide effective protection. The RSB6.8SMT2N is designed to clamp voltage transients to a safe level, protecting the ECU or ECM microcontroller from damage.

The RSB6.8SMT2N is also used in a range of other applications, including industrial and communications equipment, such as radios, switches, routers, and other equipment used in hazardous environments. In these cases, the low capacitance of the device can prevent damage to sensitive circuits in unforeseen situations.

The RSB6.8SMT2N operates by clamping high-voltage transients to a safe level. When a transient voltage is applied to the device, it will “clamp” the voltage by conducting a small current and bypassing the transient voltage to ground. This allows the suppressed voltage to remain at a safe level, protecting both the device and the power supply from damage. The diode is compact and fits into an SMT package for easy implementation into board designs.

The RSB6.8SMT2N is RoHS compliant and comes in three variants to meet different voltage, current, and capacitance requirements. With a wide operating temperature range of -55°C to 150°C, it is a reliable solution for automotive and industrial applications. Additionally, it has a reliable failure mechanism: when the current reaches a certain level, it fails open, providing a reliable level of protection.

In conclusion, the RSB6.8SMT2N is a high-performance transient voltage suppressor designed for automotive, industrial, communications, and other applications. It is designed to clamp high-voltage transients and surges to safe levels, protecting circuits from damage and providing reliable operation even in extreme conditions. With its small and ultra-low capacitance package, the RSB6.8SMT2N is an ideal solution for applications with space constraints.
