MMSZ3V9T1G-TP

TECH PUBLIC · Zener Diodes · SOD-123

MMSZ3V9T1G-TP from TECH PUBLIC, 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 CATHODE passive Cathode terminal of the Zener diode, marked CATHODE in the Pin Configuration diagram and identified by the bar on the Zener symbol. The datasheet gives no separate pin-level electrical limit; the device ratings apply, including PD of 500 mW and TJ of -55 to +150 °C.
2 ANODE passive Anode terminal of the Zener diode, marked ANODE in the Pin Configuration diagram. The datasheet gives no separate pin-level electrical limit; the device ratings apply, including VF of 0.9 V at IF = 10 mA.
