1SMA5916BT3G

onsemi · Zener Diodes · SMA

1SMA5916BT3G 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, identified by the molded polarity notch or cathode band on the package, and the Zener regulating terminal of the device (Style 1, pin 1 = cathode polarity band).
2 ANODE passive Anode terminal, the opposite terminal of the Zener diode, which is the pin not marked by the cathode polarity band (Style 1, pin 2 = anode).
