SP0502BAJTG

Littelfuse · ESD And Surge Protection (TVS/ESD) · SC-70-3

SP0502BAJTG from Littelfuse, in a SC-70-3. 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 TVS channel 1 protected line, steering-diode/avalanche array to pin 3 with 5.5V min reverse standoff, up to 5VDC, and 20kV IEC 61000-4-2 contact ESD level.
2 CH2 passive TVS channel 2 protected line, steering-diode/avalanche array to pin 3 with 5.5V min reverse standoff, up to 5VDC, and 20kV IEC 61000-4-2 contact ESD level.
3 GND power_in Common ground connection of the two-channel TVS array, shared by both channel diodes.
