PSD05C-LF-T7

ProTek Devices · ESD And Surge Protection (TVS/ESD) · SOD-323

PSD05C-LF-T7 from ProTek Devices, 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 1 passive Bidirectional TVS terminal for the protected line or bus (PSD05C: 5.0 V rated stand-off, 6.0 V minimum breakdown at 1 mA, 9.8 V maximum clamping at 1 A); polarity-independent with pin 2.
2 2 passive Bidirectional TVS terminal to the other side of the protection path, typically ground (PSD05C: 5.0 V rated stand-off, 10 µA maximum leakage at VWM, 175 pF typical capacitance at 0 V, 1 MHz); polarity-independent with pin 1.
