AZC199-04S-MS

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

AZC199-04S-MS from MSKSEMI, 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 TVS array, rated 100 W peak pulse power per line (tP=8/20µs) with IEC61000-4-2 ESD protection of ±30 kV (air and contact).
2 GND power_in Ground reference for the protection array; the clamping voltages are specified I/O pin to Ground.
3 I/O 2 bidirectional Protected I/O line 2 of the four-line TVS array, rated 100 W peak pulse power per line (tP=8/20µs) with IEC61000-4-2 ESD protection of ±30 kV (air and contact).
4 I/O 3 bidirectional Protected I/O line 3 of the four-line TVS array, rated 100 W peak pulse power per line (tP=8/20µs) with IEC61000-4-2 ESD protection of ±30 kV (air and contact).
5 VDD power_in VDD pin of the protection array as shown in the pin configuration and circuit diagram; the datasheet gives no separate voltage limit or function for this pin.
6 I/O 4 bidirectional Protected I/O line 4 of the four-line TVS array, rated 100 W peak pulse power per line (tP=8/20µs) with IEC61000-4-2 ESD protection of ±30 kV (air and contact).
