DESD5V0S1BB-7 from Diodes Incorporated, 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 single bidirectional ESD/TVS channel, rated for a 5 V maximum reverse standoff voltage (VRWM), 100 nA maximum channel leakage at 5 V, and ±30 kV contact and air ESD per IEC 61000-4-2. The datasheet labels this terminal only as pin 1 and does not assign it a polarity. |
| 2 | 2 | passive | Terminal 2 of the single bidirectional ESD/TVS channel, sharing the same 5 V maximum reverse standoff voltage, 45 pF maximum channel input capacitance (VR = 0 V, f = 1 MHz), and ±30 kV contact and air ESD per IEC 61000-4-2. The datasheet labels this terminal only as pin 2 and does not assign it a polarity. |
