# PESD15VL2BT-FS

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

PESD15VL2BT-FS from FUXINSEMI, 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 | I/O1 | passive | Protected I/O line 1 (bi-directional TVS to pin 3), working voltage 15V max, clamping 20V max at IPP=1A and 35V max at IPP=13A (8/20µs). |
| 2 | I/O2 | passive | Protected I/O line 2 (bi-directional TVS to pin 3), working voltage 15V max, clamping 20V max at IPP=1A and 35V max at IPP=13A (8/20µs). |
| 3 | COMMON | passive | Common pin of the two bi-directional TVS diodes, shared by pin 1 and pin 2 (pin1 to pin3, pin2 to pin3 clamping and 30pF typ capacitance). |
