MSKSEMI · ESD And Surge Protection (TVS/ESD) · SOT-23
AZC199-02S-MS from MSKSEMI, 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 | bidirectional | Protected data line with IEC61000-4-2 ESD protection of ±20kV (contact and air) and IEC61000-4-5 surge protection of 4A (8/20μs), with ultra-low capacitance of 0.4pF typ. |
| 2 | I/O2 | bidirectional | Protected data line with IEC61000-4-2 ESD protection of ±20kV (contact and air) and IEC61000-4-5 surge protection of 4A (8/20μs), with ultra-low capacitance of 0.4pF typ. |
| 3 | GND | power_in | Common ground reference for the two protected I/O lines; the datasheet gives no separate electrical limit for this pin. |
