TVS-Diodes are semiconductor voltage protection devices which are designed to limit overvoltages or rate of change of voltage (di/dt protection) events triggered by external transients or lightning surges. Very commonly, TVS-Diodes are used in automotive, industrial, and consumer applications to guard against possible damage due to voltage surges. The 6SMAJ26ADF is an ultra-low capacitance, low-power, small-footprint, two-channel TVS Diode Array specifically designed to protect high-speed signal lines from voltage transients induced by lighting strikes or other electrostatic discharge events. This device is AEC-Q101 qualified, making it usable in harsh automotive and other industrial applications.

The 6SMAJ26ADF offers a typical breakdown voltage of 26 volts in order to protect the signal lines. In addition, it offers an enhanced protection structure which limits any transients to less than 10 volts at its output nodes regardless of the specified transient waveforms. This device is capable of ensuring that ESD protection is at least +/- 8 kV qualified as per IEC 61000-4-2 specification, and an IEC 61000-4-5 withstand voltage of 12A. It also has a typical capacitance of 0.45 pF, making it suitable for high-speed data lines.

The 6SMAJ26ADF TVS Diode Array works by providing transient voltage suppression for two lines. It generates a low voltage at its output if the event overtaxes the normal protection level. This low voltage then forces the current to migrate through the TVS Diode Array, thus protecting the signal lines from voltage transients. The device is also configured to ensure that the robustness of the signal line protection is sustained even if the overvoltage persists beyond the normal protection range. If protection against rate of change of voltage (di/dt protection) events is necessary, then a filter capacitor can be included in the application circuit.

The 6SMAJ26ADF has multiple applications in various TVS-Diodes target markets such as automotive, industrial and consumer applications. It can be used to protect sensitive equipment from damage due to lightning strikes and other electrostatic discharge events. In automotive applications, it can be used to protect the ECU, ABS and other similar systems. In industrial applications, it can be used to protect industrial electronic systems from voltage surges. It can also be used to protect the wiring in electrical systems, both in new and already existing systems. In consumer applications, it can be used to provide protection for consumer electronic devices and home appliances such as TVs, cameras, washing machines, dishwashers, and other similar products.

In conclusion, the 6SMAJ26ADF is an ultra-low capacitance, low-power, small-footprint two-channel TVS Diode Array which offers excellent protection capability for signal lines. It is AEC-Q101 qualified and capable of ensuring ESD protection of at least +/- 8kV and an IEC 61000-4-5 withstand voltage of 12A. Its multiple applications make it suitable for use in automotive, industrial, and consumer applications.
