DT2042-04TS-7

Diodes Incorporated · ESD Protection Devices · TSOT-26

DT2042-04TS-7 from Diodes Incorporated, in a TSOT-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/O 1 bidirectional ESD-protected channel 1 I/O, rated for ±30 kV contact and air discharge per IEC 61000-4-2 with respect to VSS.
2 VSS power_in Ground reference for all I/O channels, with the operating voltage (DC) rated at 5.5 V I/O to VSS.
3 I/O 2 bidirectional ESD-protected channel 2 I/O, with a peak pulse current of ±10 A (8/20 µs) and reverse working voltage of 5.5 V relative to VSS.
4 I/O 3 bidirectional ESD-protected channel 3 I/O, with a channel input capacitance typically 1.2 pF (1.5 pF max) at VR = 2.5 V, f = 1 MHz.
5 NC unconnected Labelled NC on the top-view diagram; the datasheet specifies no function or connection for this pin.
6 I/O 4 bidirectional ESD-protected channel 4 I/O, with TLP dynamic resistance of 0.25 Ω and ESD clamping voltage of 9 V typical at 10 A to VSS.
