SSP61CC2402MR from Shanghai Siproin Microelectronics, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VOUT	output	Detector output. CMOS push-pull (C-suffix part). VOUT = Hi (following VIN, up to VIN) when VIN > VDET(+); VOUT = VSS (low) when VIN <= VDET(-). Guaranteed output sink current IOL >= 0.5 mA at VOUT = 0.2 V, VIN = 2 V.
2	GND	power_in	Ground / VSS reference for the detector. Also serves as the low-side output rail for VOUT in the CMOS output configuration.
3	VIN	power_in	Supply / sense voltage input. Absolute maximum -0.3 to 8.0 V; operating range 0.7 V to 10 V (per Electrical Characteristics VDD spec). The internal comparator monitors this pin against the 2.4 V (±2%) internal reference.
