LM-MSMF05LC from Leiditech, in a SOT-553. 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 | IO1 | passive | Protected line 1 connected through a steering diode to the common center node; the datasheet gives VRWM 5V, 0.7pF max capacitance and ±15kV air / ±8kV contact ESD ratings. |
| 2 | GND | power_in | Common center node of the diode array shown on the pin configuration, which is the reference/ground connection for the protected lines. |
| 3 | IO2 | passive | Protected line 2 connected through a steering diode to the common center node; the datasheet gives VRWM 5V, 0.7pF max capacitance and ±15kV air / ±8kV contact ESD ratings. |
| 4 | IO3 | passive | Protected line 3 connected through a steering diode to the common center node; the datasheet gives VRWM 5V, 0.7pF max capacitance and ±15kV air / ±8kV contact ESD ratings. |
| 5 | IO4 | passive | Protected line 4 connected through a steering diode to the common center node; the datasheet gives VRWM 5V, 0.7pF max capacitance and ±15kV air / ±8kV contact ESD ratings. |
