TV02W240B-HF

Comchip · ESD And Surge Protection (TVS/ESD) · SOD-123

TV02W240B-HF from Comchip, in a SOD-123. 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 A1 passive Bidirectional TVS terminal 1 (the B suffix denotes a bi-directional device with no cathode band), 24.0 V working peak reverse voltage (VRWM), 200 W peak pulse power at 10/1000µs.
2 A2 passive Bidirectional TVS terminal 2, interchangeable with terminal 1 and rated for 24.0 V VRWM, with VBR of 26.70 to 29.50 V and a maximum clamping voltage of 38.9 V.
