TP24C02S5 from TECH PUBLIC, in a SOT-23-5. 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	SCL	input	Serial clock input. Positive-edge clocks data in, negative-edge clocks data out. Schmitt-trigger filtered. Must be pulled high externally per I2C spec.
2	GND	power_in	Ground reference for the device.
3	SDA	bidirectional	Bidirectional serial data line. Open-drain output; requires an external pull-up resistor to Vcc (typ. 1.3k for 2.5-5.5V, 10k at 1.7V). Wire-OR capable with other open-drain devices.
4	Vcc	power_in	Supply voltage input, 1.7V to 5.5V. Read current 400 uA max, write current 1.6 mA max.
5	WCB	input	Write control input, active-low. Tie to GND to allow normal writes; tie to Vcc to inhibit all writes (hardware write-protect). Internally pulled down to GND when left floating.
