# BNPESD5V0L5UY

**BORN** · ESD And Surge Protection (TVS/ESD) · SOT-363

BNPESD5V0L5UY from BORN, in a SOT-363. 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 | IO1 | passive | ESD-protected data/power line 1, steering-diode clamped to pin 2 (GND), with IO-to-GND capacitance 70 pF max and IO-to-IO 30 pF at VR=0V, 1MHz. |
| 2 | GND | power_in | Common ground reference for the diode array, to which all five protected I/O lines are clamped. |
| 3 | IO2 | passive | ESD-protected data/power line 2, clamped to GND with a 5.0 V reverse stand-off voltage and 12 V max clamping at 7 A (8/20µs). |
| 4 | IO3 | passive | ESD-protected data/power line 3, rated for IEC 61000-4-2 ±15 kV contact and ±15 kV air discharge. |
| 5 | IO4 | passive | ESD-protected data/power line 4, with 6.0 V min breakdown at 1 mA and 500 nA max leakage at 5 V. |
| 6 | IO5 | passive | ESD-protected data/power line 5, with 80 W peak pulse power (8/20µs) and 7 A peak pulse current. |
