The 1.5SMB75A: The device is unidirectional (single channel), so it protects one signal or DC rail per package. It is not intended for AC power-line protection — the spec explicitly marks power line protection as 'No'.
The supplier device package is DO-214AA (SMBJ), a standard footprint shared across the 1.5SMB series. Operating junction temperature spans -65°C to 150°C, covering telecom outdoor cabinets and industrial enclosures.
