MA4E1338B1-287T from MA/COM, 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 | 1 | passive | Outer terminal of the series-pair Schottky diodes (case style 287), connected through the first diode to common pin 3; max reverse voltage 8 V. |
| 2 | 2 | passive | Outer terminal of the series-pair Schottky diodes (case style 287), connected through the second diode to common pin 3; max reverse voltage 8 V. |
| 3 | 3 | passive | Center node shared by the two series-connected Schottky diodes of the MA4E1338B1 series pair; continuous forward current 150 mA max. |
