# ESD1006B3V3B

**YFW** · Electrostatic And Surge Protection (TVS/ESD) · DFN1006-2

ESD1006B3V3B from YFW, in a DFN1006-2. 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 | Terminal 1 of the bidirectional ESD protection diode, shown as pin 1 in the schematic; the datasheet gives a 3.3 V reverse working voltage (3.3 V max) and a 14 V max clamping voltage at 8.0 A (tP = 8/20 µs) for the device across pins 1 and 2. |
| 2 | 2 | passive | Terminal 2 of the bidirectional ESD protection diode, shown as pin 2 in the schematic; the datasheet gives a 3.3 V reverse working voltage (3.3 V max) and a 14 V max clamping voltage at 8.0 A (tP = 8/20 µs) for the device across pins 1 and 2. |
