The 1SMB12AT3G from On Semiconductor is a 600W unidirectional Zener TVS diode designed for general purpose transient voltage suppression. It features a reverse standoff voltage of 12V and a clamping voltage of 19.9V at a peak pulse current of 30.2A (8/20µs waveform). The device provides 600W peak pulse power dissipation for reliable circuit protection against ESD and other voltage transients.
Packaged in a DO-214AA (SMB) surface mount package, the 1SMB12AT3G supports operating temperatures from -65°C to 150°C (junction). It is a single-channel unidirectional TVS diode suitable for general purpose applications requiring robust clamping performance with low leakage. The diode offers a capacitance of 1245pF at 1MHz, which should be considered for high-speed signal lines.
With its industry-standard SMB footprint, this TVS diode can be easily integrated into automated assembly processes. It is commonly used for protecting sensitive circuits in consumer electronics, industrial controls, and communication equipment where 12V power rails need transient protection.
