A common tvs diode for rs 485 applications is the sm712. White paperovervoltage protection for rs 485 bus nodes page 4 of 6 receivers stay operational during thermal shutdown and fault protection is active regardless of whether the driver is enabled disabled or the ic is powered down. Scn5 Sn65hvd82 How To Handle Esd Protection For Isolated Rs 485 Usb To Rs232 Rs485 Ttl Industrial Isolated Converter Rs 485 has long been a workhorse communication standard for industrial and communications electronics. Protection diode rs485 . Also its clamping voltage is close to the limit of the ti thvd1500 as seen in figure 6. A general protection scheme for an rs 485 network includes a tvs diode array such as the bourns model cdsot23 sm712 device on each node. 5 system design theory this ti design features the cdsot23 sm712 tvs diode from bourns inc series pulse proof resi...
