MBRA1H100T3G

onsemi · Schottky Barrier Diodes (SBD) · SMA

MBRA1H100T3G from onsemi, in a SMA. 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 lead, marked by the polarity band on the package and identified as Pin 1 in the SMA outline (Style 1); the device is rated 100 V VRRM and 1.0 A average forward current.
2 ANODE passive Anode lead, identified as Pin 2 in the SMA outline (Style 1), opposite the cathode polarity band.
