DO-214AB SMC package — surface mount integration
The 1.5SMC22AHM3_A/H: The wide-body SMC footprint provides adequate copper area for heat sinking during the 10/1000 µs pulse — the package's thermal impedance, not the silicon junction, sets the repetitive pulse capability. The supplier device package is identical to the package/case, simplifying land-pattern reuse across the 1.5SMC family.
Application fit — signal and data line protection
The absence of power line protection means this TVS is intended for signal, data, or low-power rail clamping, not for direct AC mains or high-current DC bus protection. Typical use cases include automotive CAN/LIN bus, telecom line cards, and industrial sensor inputs where the 18.8 V standoff matches the 24 V nominal supply with margin for transients.
