The TESDA1L2B17P1Q1 is an ESD protection device designed for a single LIN bus signal line, providing effective immunity against electrostatic discharge and transient surge events. Typical LIN applications include seat control systems, door locking modules, mirror adjustment units, and sensor interfaces such as rain sensors.
The LIN bus employs a single-wire serial communication scheme with a maximum data rate of 20 kbit/s. The operating bus voltage is approximately equal to the vehicle supply voltage, typically around 14.4V in a 12V automotive system. External ESD protection on the LIN bus is recommended to enhance module ESD robustness, as the LIN line may be shorted to the battery and must withstand the maximum battery voltage.
To maintain signal integrity at 20 kbit/s, diode capacitance should be below 100 pF, with values under 30 pF preferred.
