MMSZ4702-TP

MCC Micro Commercial Components · Zener Diodes · SOD-123

MMSZ4702-TP from MCC Micro Commercial Components, 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, the end marked with the cathode band; the Zener breakdown voltage is 15V nominal (14.25V to 15.75V) at IZT=50µA for the MMSZ4702.
2 A passive Anode; forward voltage is at most 0.95V at IF=10mA, and steady-state power dissipation is 500mW at TL<75°C.
