CDSOT23-SRV05-4

BOURNS · ESD And Surge Protection (TVS/ESD) · SOT-23-6

CDSOT23-SRV05-4 from BOURNS, in a SOT-23-6. 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 I/O 1 bidirectional Protected I/O line 1 of the four-line steering diode TVS array, rated for a 5 V working peak reverse voltage and 30 kV contact/air ESD protection per IEC 61000-4-2.
2 GND power_in Ground pin of the steering diode array, shown as GND in the block diagram; the datasheet gives no further electrical limit for it.
3 I/O 2 bidirectional Protected I/O line 2 of the four-line steering diode TVS array, rated for a 5 V working peak reverse voltage and 30 kV contact/air ESD protection per IEC 61000-4-2.
4 I/O 3 bidirectional Protected I/O line 3 of the four-line steering diode TVS array, rated for a 5 V working peak reverse voltage and 30 kV contact/air ESD protection per IEC 61000-4-2.
5 REF passive Reference pin of the steering diode array, labelled REF in the block diagram; the datasheet does not state its voltage or required connection.
6 I/O 4 bidirectional Protected I/O line 4 of the four-line steering diode TVS array, rated for a 5 V working peak reverse voltage and 30 kV contact/air ESD protection per IEC 61000-4-2.
