The device is an asymmetrical Transil diode designed specifically for one automotive LIN bus line against electrostatic discharge (ESD) protection. The SOD323 is a very small package that saves space on high density printed circuit board.
Transil diodes provide high overvoltage protection by clamping action and have instantaneous response to transient overvoltages. TM: Transil is a trademark of STMicroelectronics.
- AEC-Q101 qualified
- Asymmetrical bidirectional device
- Stand-off voltage:
- - 15 V (to comply with reverse battery)
- + 24 V (to comply with jump start)
- Low leakage current
In this video, we explain why it is important to protect against electrostatic discharges. We give a quick demonstration to show exactly what happens when you shoot at a microcontroller with an ESD gun!
