TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-23

TPSTS232033B102 from TECH PUBLIC, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	I/O1	passive	Protected line 1 of the bi-directional TVS pair, connected through back-to-back diodes to pin 3 (common), with 75 pF max junction capacitance to pin 2 and 150 pF max for pins 1,2 to pin 3.
2	I/O2	passive	Protected line 2 of the bi-directional TVS pair, connected through back-to-back diodes to pin 3 (common), with 75 pF max junction capacitance to pin 1 and 150 pF max for pins 1,2 to pin 3.
3	COMMON	passive	Common node joining the two bi-directional TVS diodes of pins 1 and 2 (3.3 V max reverse working voltage), typically tied to ground or the reference node.
