The 30.6 V ceiling is what the downstream circuitry must survive — it is the selection criterion, not the standoff rating alone. This is a unidirectional device — it protects a single polarity. If the circuit sees AC or reversed polarity during fault conditions, a bidirectional TVS or a separate polarity handling strategy is required. Operating junction temperature runs from -55 °C to 175 °C — the wide span covers outdoor enclosures, engine-bay-adjacent panels, and industrial environments without derating concerns at the low end. Tape & Box packaging is the standard pack for this axial body, which matters if your pick-and-place tooling has size constraints — confirm reel diameter and lead bend radius before committing a high-volume BOM.","metaTitle":"Vishay 1N6279A-E3/73 TVS Diode, 18.8V standoff, 1.5 kW peak","metaDescription":"Vishay 1N6279A-E3/73 TransZorb Zener TVS, 18.8V standoff, 30.6V clamping, 49A peak pulse, DO-201AA axial.
