MM1Z5V1B

hongjiacheng · Zener Diodes · SOD-123

MM1Z5V1B from hongjiacheng, in a SOD-123. 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, marked by the cathode line on the package; Zener voltage VZ is 5.0 V min to 5.20 V max (5.1 V nominal) at IZT = 5 mA for MM1Z5V1B.
2 A passive Anode of the Zener diode; forward voltage VF is 0.9 V at IF = 10 mA and power dissipation is 500 mW maximum.
