D20V0L1B2WS-7

Diodes Incorporated · ESD And Surge Protection (TVS/ESD) · SOD-323

D20V0L1B2WS-7 from Diodes Incorporated, in a SOD-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 1 passive Terminal 1 of the symmetrical bidirectional single-channel TVS, with 20V reverse standoff voltage (VRWM) and 21 to 25V breakdown at 1mA.
2 2 passive Terminal 2 of the symmetrical bidirectional single-channel TVS; either terminal can be the protected line, with ±30kV IEC 61000-4-2 contact and air ESD rating.
