PANJIT International · Zener Diodes · SMA(DO-214AC)

1SMA4740_R1_00001 from PANJIT International, in a SMA(DO-214AC). 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, marked by the color band; for the 1SMA4740 the nominal zener voltage is 10 V (9.5 V to 10.5 V) at IZT = 25 mA.
2 Anode passive Anode terminal of the zener diode; the 1SMA4740 is rated for 1 W power dissipation.
