ESD5V0B12-523 from TECH PUBLIC, 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 | TVS terminal 1 | passive | One terminal of the bidirectional TVS, rated for a nominal reverse working voltage VRWM of 5 V max, breakdown VBR of 6 V min to 9 V max, reverse leakage of 1 uA max, and clamping voltage of 8 V typ at 1 A (8x20 us) and 15 V max at 5 A. |
| 2 | TVS terminal 2 | passive | The second terminal of the bidirectional TVS, with the same ratings as pin 1 (VRWM 5 V max, VBR 6 to 9 V, IR 1 uA max, clamping 8 V typ at 1 A and 15 V max at 5 A) and 12 pF typ junction capacitance at VR = 0 V, f = 1 MHz. |
