1SMA5936BT3G-MS

MSKSEMI · Zener Diodes · SMA

1SMA5936BT3G-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, indicated by the molded polarity notch or cathode band; the Zener is reverse-biased with this pin positive to regulate at VZ (30 V nominal, 28.5 to 31.5 V at IZT = 12.5 mA for the 1SMA5936B).
2 A passive Anode of the Zener diode; forward voltage VF is 1.2 V max at IF = 200 mA.
