099-04AT1G

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

099-04AT1G from UMW, 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 CH1 bidirectional Channel 1 ESD-protected I/O line that steers ESD current to the VDD or GND rail, with a 5 V reverse working voltage and 0.9 pF max I/O-to-GND capacitance.
2 GND power_in Ground reference pin for the ESD array, connected to the negative rail, with the integrated zener between VDD and GND.
3 CH2 bidirectional Channel 2 ESD-protected I/O line that steers ESD current to the VDD or GND rail, with 0.45 pF max channel-to-channel capacitance.
4 CH3 bidirectional Channel 3 ESD-protected I/O line that steers ESD current to the VDD or GND rail, with 0.45 pF max channel-to-channel capacitance.
5 VDD power_in Positive supply rail of the ESD array, with the integrated zener connected between VDD and GND.
6 CH4 bidirectional Channel 4 ESD-protected I/O line that steers ESD current to the VDD or GND rail, with 0.45 pF max channel-to-channel capacitance.
