KPESD12VL2UT
KUU · ESD And Surge Protection (TVS/ESD) · SOT-23
KPESD12VL2UT from KUU, 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 | BASE | passive | Pin is labeled BASE on the SOT-23 outline; the datasheet gives no separate electrical limit or function for this pin, and the part is rated for a 12V stand-off voltage (VRM) with a 13.3V minimum breakdown voltage at 1mA. |
| 2 | EMITTER | passive | Pin is labeled EMITTER on the SOT-23 outline; the datasheet gives no separate electrical limit or function for this pin, and the part is rated for a 12V stand-off voltage (VRM) with a 13.3V minimum breakdown voltage at 1mA. |
| 3 | COLLECTOR | passive | Pin is labeled COLLECTOR on the SOT-23 outline; the datasheet gives no separate electrical limit or function for this pin, and the part is rated for a 12V stand-off voltage (VRM) with a 13.3V minimum breakdown voltage at 1mA. |
