Power Line Protection is listed as No — this part is not intended for continuous power-line DC clamping roles; it is a transient suppressor sized for single-event surge absorption, not a clamp that sits across the rail continuously. ## SMC footprint and thermal considerations The DO-214AB SMC package mounts flush to the PCB; the cathode band on the body identifies the terminal that connects toward the line to be protected. Surface-mount termination is tin-lead finish on the SMC grade; adequate solder mask clearance around the landing pads ensures the thermal path from the diode body to the board copper carries the surge heat away without the solder joint becoming the bottleneck.","metaTitle":"Diotec 1.5SMCJ85CA TVS Diode, 1500W Peak, 85V Standoff","metaDescription":"Diotec 1.5SMCJ85CA bidirectional TVS diode, 1500W peak pulse, 85V standoff, 137V clamping, DO-214AB SMC package, active production.
