D5V0H2U3SO-7

Diodes Incorporated · ESD And Surge Protection (TVS/ESD) · SOT-23-3

D5V0H2U3SO-7 from Diodes Incorporated, in a SOT-23-3. 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/O1 passive ESD-protected line 1 (unidirectional channel, diode to pin 3 and to ground); connecting pin 1 to pin 2 allows bidirectional use.
2 I/O2 passive ESD-protected line 2 (unidirectional channel); connecting only pin 1 to pin 2 lets the device work as a bidirectional suppressor.
3 GND power_in Common reference/ground pin of the dual ESD protection device schematic.
