SZ1SMB12AT3G Description

Short technical summary and product information.

The SZ1SMB12AT3G is an automotive-grade TVS diode from Littelfuse Inc., designed for transient voltage suppression in vehicle electronics. It features a 12V reverse standoff voltage (typical) and a minimum breakdown voltage of 13.3V. The device clamps transient voltages to a maximum of 19.9V at a peak pulse current of 30.2A (10/1000µs waveform). With a peak pulse power rating of 600W, it provides robust protection against voltage spikes. The component is unidirectional with a single protection channel and has a typical capacitance of 1245pF at 1MHz. It is housed in a DO-214AA (SMB) surface-mount package and supports an operating temperature range of -65°C to 150°C. Ideal for automotive applications where reliability under harsh conditions is required.
