MBRA140T3G

onsemi · Schottky Barrier Diodes (SBD) · SMA(DO-214AC)

MBRA140T3G from onsemi, in a SMA(DO-214AC). 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 CATHODE passive Cathode terminal, marked by the polarity band on the package; the device is rated for a 40 V peak repetitive reverse voltage (VRRM) and 1.0 A average rectified forward current at TC = 95°C.
2 ANODE passive Anode terminal; the device has a non-repetitive peak surge forward current rating of 30 A (halfwave, single phase, 60 Hz) and an operating junction temperature range of −55 to +125 °C.
