TPAZC199-04S

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

TPAZC199-04S from TECH PUBLIC, 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 IO1 passive I/O protected data line 1 (Note 1: I/O pins are 1, 3, 4 and 6); reverse working voltage 5V max to ground, 0.3pF typ between I/O pins.
2 GND power_in Ground reference pin connected to the TVS diode in the center of the schematic; I/O pins are rated to this pin with VRWM 5V max.
3 IO2 passive I/O protected data line (Note 1: I/O pins are 1, 3, 4 and 6); reverse working voltage 5V max to ground, 0.8pF max to ground.
4 IO3 passive I/O protected data line (Note 1: I/O pins are 1, 3, 4 and 6); clamping voltage 15V max at IPP=1A (8x20µs).
5 VCC power_in Center pin of the schematic connected to the TVS diode cathode, which the features list calls the power line protected; the datasheet does not name it explicitly.
6 IO4 passive I/O protected data line (Note 1: I/O pins are 1, 3, 4 and 6); clamping voltage 20V max at IPP=4A (8x20µs).
