The unidirectional polarity means it clamps only one polarity — for AC rails or bidirectional fast transients a bidirectional (B) variant would be needed; this is a single-polarity clamp only. ## Junction temperature and mounting Rated junction temperature spans -50 °C to 150 °C, covering the industrial ambient envelope for enclosed panels and equipment rooms. Surface-mount SMC body — the solder-tab footprint under the cathode tab is the thermal dissipation path; adequate pad coverage and via-in-pad to the ground plane matter for peak pulse thermal management.","metaTitle":"Diotec 1.5SMCJ9.0A TVS Diode, 1500W Peak, 9V Standoff","metaDescription":"Diotec 1.5SMCJ9.0A unidirectional Zener TVS diode, 1500W peak pulse, 9V standoff/10V breakdown, DO-214AB SMC.
