DT1446-04TS-7

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

DT1446-04TS-7 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 I/O 1 passive ESD-protected high-speed I/O line 1, steered to Vcc/Vss by diodes, with 0.3pF typical I/O-to-I/O capacitance and 5V max reverse working voltage.
2 Vss power_in Ground reference of the TVS array, to which the I/O pins are clamped.
3 I/O 2 passive ESD-protected high-speed I/O line 2, rated for IEC 61000-4-2 ±25kV air and ±20kV contact discharge.
4 I/O 3 passive ESD-protected high-speed I/O line 3, with 0.8pF max junction capacitance to ground and 15V max clamping at 4.0A (8x20µs).
5 Vcc power_in Positive supply/power line connection of the array; the datasheet states it protects one power line and a 5V low operating voltage.
6 I/O 4 passive ESD-protected high-speed I/O line 4, with 0.08µA max leakage at VRWM = 5V.
