The CA suffix marks the bidirectional configuration; the CAs protect signal rails and telecom equipment bus rails where the polarity of the transient is undefined. ## Clamping voltage and the protection envelope The reverse standoff of 70.1 V sets the working rail — the part idles below this voltage without conducting. That 113 V clamping ceiling is what the downstream circuitry must survive — select downstream components with absolute-maximum ratings above this level. Sustained or repetitive transients above this rating cause thermal runaway — the TJ ceiling is 150 °C, so thermal relief and board copper area under the SMC tab directly affect survivable event count. ## Temperature grade and telecom deployment The lower bound matters for outdoor telecom cabinets in cold climates; the upper bound defines the thermal headroom available above the worst-case ambient in a sealed enclosure. The automotive qualification (AEC-Q101) implies tighter screening and gate-life consistency than the standard industrial grade — a meaningful reliability margin for telecom infrastructure that runs unattended in remote cabinets. ## Sourcing posture Sourced to order against BOM quantity; availability and current lead time confirmed at quote. The base number 1.5SMC82 covers a range of standoff voltages in this package — if this exact code is not available, the 1.5SMC family is the cross-reference starting point.","metaTitle":"Vishay 1.5SMC82CAHM3/I TVS Diode, 70.1V standoff, 1.5 kW","metaDescription":"Vishay 1.5SMC82CAHM3/I, automotive AEC-Q101 Zener TVS, bidirectional, 70.1 V standoff, 113 V clamping, 13.3 A peak pulse, DO-214AB SMC.
