ESD5VFBD523 from YFW, in a SOD-523. 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 TVS, which protects one I/O or power line with a reverse stand-off voltage (VRWM) of 5.0 V max, breakdown 5.6 V min to 7.4 V max at 1 mA, clamping 9.5 V max at IPP = 8 A (tP = 8/20 µs), and 100 W peak pulse power. |
| 2 | 2 | passive | Terminal 2 of the bidirectional TVS, which has the same limits as pin 1: VRWM 5.0 V max, breakdown 5.6 V min to 7.4 V max at 1 mA, clamping 9.5 V max at 8 A, and ESD protection rated ±30 kV contact and air per IEC 61000-4-2. |
