CDSOD323-T03C
BOURNS · ESD And Surge Protection (TVS/ESD) · SOD-323
CDSOD323-T03C from BOURNS, in a SOD-323. 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 | Bidirectional TVS terminal 1 (no polarity band on the C suffix part); protects one line or I/O port with VWM 3.3 V, minimum VBR 4.0 V @ 1 mA, and maximum VC 7.0 V @ IP = 1 A. |
| 2 | 2 | passive | Bidirectional TVS terminal 2; electrical specifications apply in both directions, with typical capacitance of 3 pF at 0 V, 1 MHz. |
