SZESD7205WTT1G

onsemi · ESD Protection Devices · SOT-323

SZESD7205WTT1G from onsemi, in a SOT-323. 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 I/O line 1 (Pin 1), flow-through, with 0.34 pF typ to 0.47 pF typ junction capacitance to GND and 5.0 V reverse working voltage.
2 I/O2 passive ESD-protected I/O line 2 (Pin 2), flow-through, with 5.0 V reverse working voltage and capacitance matched to I/O1 within 5% typ, 10% max.
3 GND power_in Ground reference (Pin 3) common to both I/O protection diodes.
