The 1.5SMB39CA: The reverse standoff voltage of 33.3 V means the diode does not conduct at normal operating levels up to that rail; breakdown begins at 37.1 V minimum, and clamping is guaranteed at 69.6 V maximum at the rated current. Operating temperature spans -65°C to 150°C junction, covering outdoor telecom cabinets and industrial enclosures without derating concerns at the high end.
