MSKSEMI · ESD And Surge Protection (TVS/ESD) · SOT-23
SDT23C12L02-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 | passive | Protected bidirectional line 1, connected through a back-to-back TVS diode pair to common pin 3; the datasheet gives ESD ratings of ±30kV contact and ±30kV air per IEC61000-4-2. |
| 2 | I/O2 | passive | Protected bidirectional line 2, connected through a back-to-back TVS diode pair to common pin 3; the datasheet gives ESD ratings of ±30kV contact and ±30kV air per IEC61000-4-2. |
| 3 | COMMON | passive | Common node shared by both TVS diode pairs, shown joined to pins 1 and 2 through the diodes in the pin configuration drawing; the datasheet does not name it GND. |
