1SMA5913BT3G

onsemi · Zener Diodes · SMA

1SMA5913BT3G 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 terminal of the Zener diode, identified on the package by the polarity band (Style 1: pin 1 = cathode, polarity band).
2 ANODE passive Anode terminal of the Zener diode (Style 1: pin 2 = anode).
