1SMB30CAT3G Description

Short technical summary and product information.

The 1SMB30CAT3G is a bidirectional Zener TVS diode designed for general-purpose overvoltage protection. It features a reverse standoff voltage of 30V and a minimum breakdown voltage of 33.3V. When subjected to a transient event, the device clamps at a maximum of 48.4V while handling a peak pulse current of 12.4A (10/1000µs waveform).

 

With a peak pulse power rating of 600W, this diode is suitable for protecting sensitive electronics from voltage spikes. It is housed in a DO-214AA (SMB) surface-mount package and operates over a wide temperature range of -65°C to 150°C. The device has a typical capacitance of 290pF at 1MHz, making it appropriate for general-purpose applications where moderate speed is acceptable.

 

The 1SMB30CAT3G is not intended for power line protection and is best suited for signal or low-power DC rail protection. Its surface-mount package facilitates automated assembly and compact PCB layouts.
