SP0504BAJTG

Leiditech · ESD And Surge Protection (TVS/ESD) · SOT-353

SP0504BAJTG from Leiditech, in a SOT-353. 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/O1 passive ESD-protected line 1 of the quad array, rated for ±30kV air and ±25kV contact discharge per IEC 61000-4-2.
2 GND power_in Common node of the diode array, drawn in the pin configuration as the center bottom pin tied to the internal common line.
3 I/O2 passive ESD-protected line 2 of the quad array, rated for ±30kV air and ±25kV contact discharge per IEC 61000-4-2.
4 I/O3 passive ESD-protected line 3 of the quad array, with 5V reverse working voltage and 150W peak pulse power (8/20µs).
5 I/O4 passive ESD-protected line 4 of the quad array, with 5V reverse working voltage and 150W peak pulse power (8/20µs).
