MA4E1338B1-287T

MA/COM · Diodes - General Purpose · SOT-23

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.
