PANJIT International · ESD And Surge Protection (TVS/ESD) · SOT-23
PEC3324C2A-AU_R1_000A1 from PANJIT International, 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 | ESD-protected I/O line 1 (diode to common pin 3), reverse stand-off 24 V, breakdown 26.2 V to 30.3 V at 1 mA, 25 pF typical capacitance to GND. |
| 2 | I/O2 | passive | ESD-protected I/O line 2 (diode to common pin 3), reverse stand-off 24 V, breakdown 26.2 V to 30.3 V at 1 mA, 25 pF typical capacitance to GND. |
| 3 | GND | power_in | Common connection of the two protection diodes, the ground reference for the I/O pins; the datasheet specifies clamping voltage of any I/O pin to GND. |
