Rated for -40°C to 85°C ambient, this part is suited for industrial control panels, outdoor telecom cabinets, and factory-floor equipment where the electronics see seasonal temperature swings but not under-hood extremes. The SOT-143-4 package keeps the footprint small for dense PCB layouts.
That means no LTB pressure for existing BOM lines and no need to qualify a replacement for new designs.
The operating temperature range is -40°C to 85°C ambient. It monitors a single supply voltage and is mounted surface-mount in a SOT-143-4 package.
