PLR0521

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · DFN1006-2

PLR0521 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 terminal of the bidirectional TVS diode, with the device rated for a reverse working voltage (VRWM) of 5 V max and a peak pulse current (8/20µs) of 4 A, as given in the absolute maximum and electrical tables.
2 Terminal 2 passive The other terminal of the bidirectional TVS diode, with a typical junction capacitance of 0.3 pF at VR = 0 V and f = 1 MHz, as given in the electrical characteristics table.
