CDSOT23-SLVU2.8 from BOURNS, in a SOT-23. 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 | Common reference node for all stated TVS measurements, with leakage, clamping and capacitance specified Pin 3 to Pin 1 or Pin 2 to Pin 1; the datasheet does not label it as ground. |
| 2 | 2 | passive | Maximum clamping voltage is 7.0 V at IP = 5 A and 8.5 V at IP = 5 A measured Pin 2 to Pin 1, with 30 A clamping of 21.0 V and a 2.5 pF typical junction capacitance when Pin 3 is NC. |
| 3 | 3 | passive | Leakage is 1.0 µA maximum at VWM = 2.8 V measured Pin 3 to Pin 1, and typical junction capacitance is 20 pF measured Pin 3 to Pin 1 and Pin 2; Pin 3 may be left NC in the Pin 2 to Pin 1 configuration. |
