The onsemi 1SMA12AT3 is a transient voltage suppressor (TVS) diode designed for robust protection in demanding applications. This component offers a 12V reverse standoff voltage (Vrwm) with a low clamping voltage of 19.9V at a peak pulse current (Ipp) of 20.1A for a 10/1000µs waveform. It features a 400W peak pulse power rating and operates across a wide temperature range of -65°C to 150°C (TJ). The device is housed in a compact DO-214AC, SMA surface-mount package, supplied on tape and reel. Its low capacitance of 925pF at 1MHz makes it suitable for general-purpose applications where effective transient suppression is critical, including industrial and automotive systems.
