onsemi · ESD And Surge Protection (TVS/ESD) · SOT-23
MMBZ15VALT1G 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 | CATHODE 1 | passive | Cathode of the first Zener junction; with pin 3 (anode) it forms one unidirectional TVS path, and the datasheet gives the MMBZ15VALT1G working peak reverse voltage as 12 V with 40 W peak power at 1.0 ms. |
| 2 | CATHODE 2 | passive | Cathode of the second Zener junction; with pin 3 (anode) it forms a second unidirectional TVS path, or pins 1 and 2 can be used together with pin 3 for a single bidirectional configuration. |
| 3 | ANODE | passive | Common anode shared by both Zener junctions; the datasheet states the device protects two separate lines using one package, with a 15 V nominal breakdown (14.25 V min to 15.75 V max) for the MMBZ15VALT1G. |
