SMDA03-6E3

Microsemi · TVS · SO-8

SMDA03-6E3 from Microsemi, in a SO-8. 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 Protected unidirectional data/interface line 1 of the 6-line TVS array; SMDA03-6 has a 3.3 V maximum standoff voltage (VWM) per line.
2 I/O 2 passive Protected unidirectional data/interface line 2 of the 6-line TVS array; SMDA03-6 has a 3.3 V maximum standoff voltage (VWM) per line.
3 I/O 3 passive Protected unidirectional data/interface line 3 of the 6-line TVS array; SMDA03-6 has a 3.3 V maximum standoff voltage (VWM) per line.
4 I/O 4 passive Protected unidirectional data/interface line 4 of the 6-line TVS array; SMDA03-6 has a 3.3 V maximum standoff voltage (VWM) per line.
5 I/O 5 passive Protected unidirectional data/interface line 5 of the 6-line TVS array; SMDA03-6 has a 3.3 V maximum standoff voltage (VWM) per line.
6 GND power_in Common ground reference for the TVS array diodes, shown tied internally with the other GND pin in the circuit diagram.
7 GND power_in Common ground reference for the TVS array diodes, shown tied internally with the other GND pin in the circuit diagram.
8 I/O 6 passive Protected unidirectional data/interface line 6 of the 6-line TVS array; SMDA03-6 has a 3.3 V maximum standoff voltage (VWM) per line.
