SM08C
MDD(Microdiode Semiconductor) · IC · SOT-23
SM08C from MDD(Microdiode Semiconductor), 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/O 1 | passive | Protected bidirectional line 1, clamped to common pin 3 through a bidirectional TVS diode (SM08C VRWM 8 V, VB 8.5 V min at 1 mA). |
| 2 | I/O 2 | passive | Protected bidirectional line 2, clamped to common pin 3 through a bidirectional TVS diode (SM08C VRWM 8 V, VB 8.5 V min at 1 mA). |
| 3 | COMMON | passive | Common node shared by both bidirectional TVS diodes, connected to the reference/ground return of the protected lines. |
