The \"CA\" suffix marks the bidirectional polarity configuration; the \"HM3_A/I\" ordering code variant carries the automotive grade and internal construction specific to this exact ordering code. ## Clamping performance — what the voltage and current ratings mean Reverse standoff is 70.1 V typ, meaning the device idles invisible across the rail until a transient pushes it into conduction. When it clamps, the maximum clamping voltage at the rated peak pulse current is 113 V — that is the ceiling the downstream circuitry sees even if the surge exceeds the part's peak rating. These two figures are linked: at 113 V clamping, 13.3 A × 113 V ≈ 1500 W, so a surge that holds the clamping voltage lower than 113 V also carries lower peak current — both specs must be satisfied simultaneously for the device to survive within its rated SOA. The minimum breakdown voltage is 77.9 V — the device turns on above this level in either polarity. For a bidirectional suppressor, this symmetric knee is the key design parameter: the system rail sits below standoff, and any overvoltage above 77.9 V is clamped before it reaches the load. ## Thermal margin and package for automotive environments Junction temperature is rated to 150 °C, which aligns with the AEC-Q101 automotive thermal envelope and covers the under-hood and engine-bay bands where ambient can spike well above 125 °C. The DO-214AB (SMC) package is the standard surface-mount footprint for 1.5–3 kW TVS parts — the cathode bar on the top of the package is the thermal interface; board pad design and solder coverage directly affect the thermal resistance junction-to-ambient. The part is surface-mount, supplied on tape and reel for automated placement. Confirm the exact reel quantity against your pick-and-place tooling — the \"_A/I\" suffix in the ordering code specifies the tape-and-reel orientation and automotive packaging requirement, which is a common catch point when cross-referencing to the base 1.5SMC82C variant. ## Sourcing — lifecycle and availability The \"_A/I\" suffix in the ordering code designates the automotive grade and internal construction of this specific variant — confirm this is the exact code your BOM calls out. The base 1.5SMC82C part shares the same 82 V Zener family but differs in the suffix-coded construction and AEC-Q101 sub-variant; swapping to a non-suffix-matched code without engineering sign-off is not recommended.","metaTitle":"Vishay 1.5SMC82CAHM3_A/I TVS Diode, 113V Clamping","metaDescription":"1.5SMC82CAHM3_A/I — Automotive AEC-Q101 bidirectional TVS Zener, 70.1V standoff, 113V clamping, 1500W peak pulse, DO-214AB SMC.
