MMBZ15VDLT1G

onsemi · ESD And Surge Protection (TVS/ESD) · SOT-23

MMBZ15VDLT1G from onsemi, in a SOT-23. 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 ANODE 1 passive Anode of the first zener diode of the dual common-cathode pair; for unidirectional use the circuit is tied between pins 1 and 3.
2 ANODE 2 passive Anode of the second zener diode of the dual common-cathode pair; for unidirectional use the circuit is tied between pins 2 and 3.
3 CATHODE passive Common cathode shared by both zener diodes, which allows two separate unidirectional lines or a single bidirectional configuration.
