MMBZ39VCLT1G-N from BORN, 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 | 1 | passive | One of the two ESD protection diode line terminals; the datasheet gives 12 pF typical junction capacitance measured from pins 1 and 2 to pin 3 at VR = 0 V, f = 1 MHz. |
| 2 | 2 | passive | The second ESD protection diode line terminal; the datasheet gives 12 pF typical junction capacitance measured from pins 1 and 2 to pin 3 at VR = 0 V, f = 1 MHz. |
| 3 | 3 | passive | Common terminal of the diode array, rated for 36 V reverse stand-off (VRWM), 40 to 50 V breakdown at 1 mA, and 4 A peak pulse current (8/20 µs). |
