SLVU2.8-4-LF-T7

ProTek Devices · ESD Protection Devices · SO-8

SLVU2.8-4-LF-T7 from ProTek Devices, 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 Line Pair 1 (pin 1) passive Pin 1 is one terminal of Line Pair 1, with the datasheet measuring the clamp between pin 1 and pin 2, rated at 2.8 V stand-off (VWM) with leakage below 1.0 µA and typical capacitance of 3 pF.
2 GND passive Pin 2 is the other terminal of Line Pair 1 (measured against pin 1), but the common-mode application example also lists pin 2 as connected to ground, so its role depends on the configuration used.
3 Line Pair 2 (pin 3) passive Pin 3 is one terminal of Line Pair 2, measured against pin 4, and is used as Line 3 in the common-mode example.
4 GND passive Pin 4 is the other terminal of Line Pair 2 (measured against pin 3), but the common-mode application example also lists pin 4 as connected to ground.
5 Line Pair 2 (pin 5) passive Pin 5 is one terminal of Line Pair 2, measured against pin 6, and is used as Line 4 in the common-mode example.
6 GND passive Pin 6 is the other terminal of Line Pair 2 (measured against pin 5) in the differential-mode configuration.
7 Line Pair 1 (pin 7) passive Pin 7 is one terminal of Line Pair 1, measured against pin 8, and is listed as Line 2 in the common-mode example although the same text also lists it as connected to ground.
8 GND passive Pin 8 is the other terminal of Line Pair 1 (measured against pin 7) in the differential-mode configuration.
