SMA2Z4.7A

XCH(旭昌辉) · IC · SMA

SMA2Z4.7A from XCH(旭昌辉), 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, the end of the SMA body with the marking band; it is positive with respect to the anode in zener (reverse) operation, with VZ 4.46 V min / 4.7 V nom / 4.94 V max at IZT = 106 mA.
2 A passive Anode, the lead at the unbanded end of the SMA body; forward voltage is 1.2 V at IF = 200 mA.

CAD (KiCad official)

  • Symbol: SMA2Z4.7A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: sma2z4-7a-etched.step / sma2z4-7a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sma2z4-7a.step / sma2z4-7a.glb are the bare package body.
