MMSZ4708-TP

MCC Micro Commercial Components · Zener Diodes · SOD-123

MMSZ4708-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 (marked end of the body); the Zener breakdown voltage for MMSZ4708 is 22V nominal (20.9V to 23.1V) at IZT=50µA, with IR 0.01µA max at VR=16.7V.
2 A passive Anode; maximum forward voltage is 0.95V at IF=10mA and steady-state power dissipation is 500mW at TL<75°C.
