ST0561D4-P

TECH PUBLIC · ESD Protection Devices · DFN1006-2

ST0561D4-P from TECH PUBLIC, in a DFN1006-2. 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 Terminal 1 passive One of the two terminals of the bidirectional TVS diode, which has a 5 V maximum reverse working voltage (VRWM) and a 5.6 V minimum breakdown voltage (VBR) at 1 mA.
2 Terminal 2 passive The other terminal of the bidirectional TVS diode, which clamps to 10 V maximum at Ipp = 8 A (8/20 µs pulse) and has 15 pF typical junction capacitance at VR = 0 V, f = 1 MHz.
