Above that, breakdown occurs at 133V minimum, and the clamp voltage peaks at 193V at the rated 2A peak pulse current. For a 120V bus, that clamp margin means downstream components rated for at least 200V see a protected transient. That energy envelope covers typical ESD, inductive kickback, and lightning-induced transients on outdoor or industrial cabling, but not direct mains strikes. The single bidirectional channel means one device protects both positive and negative polarity surges, simplifying BOM count on a dual-supply or AC-coupled signal line. ## Package, temperature range, and deployment context Housed in the DO-214AC (SMA) surface-mount package, the SMAJ120CA-13-F shares the same footprint as hundreds of standard TVS diodes — a drop-in replacement for existing 120V bidirectional SMA designs. The -55°C to 150°C junction temperature range covers outdoor telecom cabinets, industrial control enclosures, and under-hood automotive modules where ambient heat soaks above 85°C. The device is marked as not intended for power line protection, so it belongs on data, signal, or low-power supply rails, not AC mains inputs.","metaTitle":"SMAJ120CA-13-F Diodes Inc TVS Diode, 120V, 400W, DO-214AC","metaDescription":"SMAJ120CA-13-F bidirectional Zener TVS, 120V standoff, 193V clamp, 400W peak pulse.
