TPGC05C-1

TECH PUBLIC · ESD Protection Devices · SOD-323

TPGC05C-1 from TECH PUBLIC, in a SOD-323. 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 Line 1 passive Top terminal of the bidirectional TVS, tied to pin 2 through two back-to-back diode pairs in the schematic, protecting one power or data line with a 5 V maximum reverse working voltage.
2 Line 2 passive Bottom terminal of the bidirectional TVS, joined to pin 1 through the same two back-to-back diode pairs, with a 9 V maximum clamping voltage at 1 A IPP (8 x 20 µs pulse).
