Description

This reference design proposes an implementation of combining Positive Temperature Coefficient (PTC) fuses and Silicon Diode Alternating Current (SIDAC) devices to keep the transceivers alive under sustained exposure to high voltage. It highlights the capability of this particular protection device combination for RS-485 transceivers.

Features
  • 15V low-voltage SIDAC
  • 120/240V PTC fuse
  • Extra pads for alternative device testing
  • Headers for easy connections
