NUP2105LT1G

NUP2105LT1G is an onsemi dual bidirectional TVS array in SOT-23-3 (TO-236), tape and reel — purpose-built transient protection for CAN bus lines in automotive and industrial networks. The protection figures are the selection point, and one of them is routinely misquoted: the 350 W peak pulse power is per line on the 8/20 µs waveform, not a whole-device figure. Working peak reverse voltage is 24 V, breakdown is 26.2 V minimum, and clamping is 44 V maximum at IPP = 8 A (8/20 µs) — the window a CAN transceiver's bus pins must survive. Capacitance is 26 pF typical and 30 pF maximum at VR = 0 V and f = 1 MHz, line-to-ground at TJ = 25 °C, low enough to keep CAN edges clean, and the junction range is −55 to +150 °C. Selection advice: place the array at the connector, keep its ground path short, and do not substitute a general-purpose ESD part with higher capacitance on a fast bus — the capacitance, not the wattage, is usually what breaks the signal integrity budget. onsemi status wording for this code was not captured for this record, so no status is claimed here — the offered lot is confirmed against your requirement before quotation.
