Zener TVS for 24V signal-line clamping
The NUP2105LT1G is an onsemi Zener-type TVS diode designed for general-purpose circuit protection. It provides bidirectional clamping across two channels in a single SOT-23-3 package. With a 24V minimum reverse standoff voltage and a 44V maximum clamping at 8A peak pulse (8/20µs waveform), it suits 24V power or data lines where overvoltage events must be shunted without interrupting normal operation.
Capacitance and signal integrity
Typical capacitance is 30pF at 1MHz — low enough for most low-speed data interfaces (CAN, RS-485, I²C) but not intended for high-frequency RF lines where sub-5pF parts are preferred. The device does not include power-line protection features; it is a dedicated signal-line clamp.
Housed in a surface-mount SOT-23-3 (TO-236) package, supplied on Tape & Reel or Cut Tape. onsemi lists the product status as Active, meaning ongoing production with no announced end-of-life.
