1SMA5927BT3G-MS

MSKSEMI · Zener Diodes · SMA

1SMA5927BT3G-MS from MSKSEMI, 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 K passive Cathode, marked by the molded polarity notch or cathode band; it goes positive for reverse Zener regulation (VZ 12 V nominal for the 1SMA5927B).
2 A passive Anode, the end opposite the cathode band; forward conduction has VF = 1.2 V max at IF = 200 mA.
