The SMCJ70CA with SMC TVS RoHS is an electronic part manufactured by TWGMC. It is a unidirectional, surface mount TVS diode that can be used to protect high-speed communication lines from over-voltage transients. It is constructed using silicon, 200W, and comes in a small, lead-free 4-pin SMC package. The SMCJ70CA has an operating junction temperature range of -55°C to 150°C with a fast response time of less than 5ns, and a maximum clamping voltage of 70V. The SMCJ70CA is also compliant with RoHS Directive 2011/65/EU and has multiple applications including telecommunications, networking, consumer electronics, and automotive electronics.
