RS-485

RS-485 ESD Protection

RS-485 has long been a workhorse communication standard for industrial and communications electronics. RS-485 is still widely prevalent today for its advantages in robust, high noise immunity electrical communication. From high-end base stations to surveillance to HVAC control to POS terminals to industrial networks, RS-485 is everywhere. The harsh environments and long distances over which RS-485 links run mean that they are often assaulted with a broad range of electrical transient spikes. Semtech makes highly differentiated TVS protection to safeguard RS-485 ports from the most harsh electrical conditions.
