The onsemi 1SMB28AT3 is a transient voltage suppressor (TVS) diode designed for robust protection in demanding applications. Featuring a reverse standoff voltage of 28V and a breakdown voltage of 31.1V (minimum), this component effectively clamps transient surges to a maximum of 45.4V at a peak pulse current of 13.2A. With a peak pulse power rating of 600W, it offers significant protection against overvoltage events. The device is housed in a compact DO-214AA SMB package, suitable for surface mounting and available on tape and reel. Its low capacitance of 590pF at 1MHz makes it adaptable for various signal and power line protection scenarios across general-purpose applications. Operating within a wide temperature range of -65°C to 150°C, the 1SMB28AT3 from onsemi provides reliable transient suppression for sensitive electronic systems.
