MSKSEMI · Zener Diodes · SMA

1SMA5932BT3G-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 of the Zener diode, indicated by the molded polarity notch or cathode band; the 1SMA5932B has a 20 V nominal Zener voltage (19 V min to 21 V max) at IZT = 18.7 mA.
2 A passive Anode of the Zener diode; the datasheet gives a maximum DC power dissipation of 1.5 W at TL = 75°C and 0.5 W at TA = 25°C.
