HDMIULC6-4SC6

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

HDMIULC6-4SC6 from STMicroelectronics, in a SOT-23-6L. 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 signal line 1 (rail-to-rail clamp to GND/VBUS), max leakage 0.5 µA at 5 V, clamping voltage 12 V @1A/17 V @5A (8/20 µs).
2 GND power_in Ground reference for the ESD protection array; breakdown voltage between VBUS and GND is 6 V at 1 mA.
3 I/O2 passive ESD-protected signal line 2 (rail-to-rail clamp to GND/VBUS), max leakage 0.5 µA at 5 V, clamping voltage 12 V @1A/17 V @5A (8/20 µs).
4 I/O3 passive ESD-protected signal line 3 (rail-to-rail clamp to GND/VBUS), max leakage 0.5 µA at 5 V, clamping voltage 12 V @1A/17 V @5A (8/20 µs).
5 VBUS power_in Optional VBUS supply protection pin, clamped between GND and I/O lines; in HDMI applications this pin should be left unconnected to avoid backdrive current flow.
6 I/O4 passive ESD-protected signal line 4 (rail-to-rail clamp to GND/VBUS), max leakage 0.5 µA at 5 V, clamping voltage 12 V @1A/17 V @5A (8/20 µs).
