DT2041-04SO-7

Diodes Incorporated · ESD And Surge Protection (TVS/ESD) · SOT-26

DT2041-04SO-7 from Diodes Incorporated, in a SOT-26. 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 high-speed I/O channel 1 (typ. 1.0pF, max 1.5pF), clamped to VSS with ±10A 8/20µs surge rating and ±30kV IEC 61000-4-2 protection.
2 VSS power_in Ground reference (VSS) for the TVS array; all I/O and VCC clamping is referenced to this pin.
3 I/O2 passive ESD-protected high-speed I/O channel 2 (typ. 1.0pF, max 1.5pF), clamped to VSS with ±10A 8/20µs surge rating and ±30kV IEC 61000-4-2 protection.
4 I/O3 passive ESD-protected high-speed I/O channel 3 (typ. 1.0pF, max 1.5pF), clamped to VSS with ±10A 8/20µs surge rating and ±30kV IEC 61000-4-2 protection.
5 VCC power_in Positive supply/rail pin for the steering diodes, with 5.5V max operating voltage and ±12A 8/20µs surge rating VCC to VSS.
6 I/O4 passive ESD-protected high-speed I/O channel 4 (typ. 1.0pF, max 1.5pF), clamped to VSS with ±10A 8/20µs surge rating and ±30kV IEC 61000-4-2 protection.
