SZA6.8A

LRC · Zener Diodes · DO-214AC(SMA)

SZA6.8A from LRC, in a DO-214AC(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 color band on the DO-214AC molded plastic case; Zener voltage 6.8V at Izt 37mA for SZA6.8A.
2 A passive Anode terminal of the Zener diode, opposite the cathode marking band; 1.0W steady state power dissipation at TL=75°C.
