SPD9103W

TECH PUBLIC · MOSFETs · SOD-323

SPD9103W 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 1 passive Pin 1 is one terminal of the bidirectional TVS clamp, tied to the top node of the internal diode network; the datasheet gives a Nominal Reverse Working Voltage (VRWM) of 3.3 V max and a Breakdown Voltage (VBR) of 4 V min at IT = 1 mA.
2 2 passive Pin 2 is the other terminal of the bidirectional TVS clamp, tied to the bottom node of the internal diode network; the datasheet gives a Junction Capacitance of 1 pF typical at VR = 0 V, f = 1 MHz and a Clamping Voltage of 9 V max at IPP = 1 A (8/20 µs).
