CDDFN10-3304NA

BOURNS · ESD And Surge Protection (TVS/ESD) · TDFN-10-EP(2.5x2.5)

CDDFN10-3304NA from BOURNS, in a TDFN-10-EP(2.5x2.5). 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	CH1	passive	I/O data line 1 protected by the TVS steering diode array (4 pF typical junction capacitance to ground, 3.3 V working voltage).
2	NC	unconnected	No connection.
3	CH3	passive	I/O data line 3 protected by the TVS steering diode array (4 pF typical junction capacitance to ground, 3.3 V working voltage).
4	NC	unconnected	No connection.
5	VDD	power_in	Steering diode supply reference pin; leakage specified at VRWM 3.3 V with pin 5 to ground, 1 µA max.
6	NC	unconnected	No connection.
7	CH4	passive	I/O data line 4 protected by the TVS steering diode array (4 pF typical junction capacitance to ground, 3.3 V working voltage).
8	NC	unconnected	No connection.
9	CH2	passive	I/O data line 2 protected by the TVS steering diode array (4 pF typical junction capacitance to ground, 3.3 V working voltage).
10	NC	unconnected	No connection.
11	GND	power_in	Center tab ground pad of the DFN-10 package, the ground reference for all I/O clamping.

CAD (KiCad official)

Symbol: CDDFN10-3304NA
Footprint: Package_DFN_QFN:DFN-10-1EP_2.6x2.6mm_P0.5mm_EP1.3x2.2mm
3D model: TDFN-10-EP(2.5x2.5), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal QFN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
3D model files: cddfn10-3304na-etched.step / cddfn10-3304na-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cddfn10-3304na.step / cddfn10-3304na.glb are the bare package body.
