Product details

The P6SMB68AT3: For existing BOM lines, procurement must source through independent distribution or broker channels; we can quote to order against your quantity.

600W peak pulse, 58.1V standoff – what it protects

The clamping voltage at 6.5A peak pulse current is 92V max. It is designed to protect a single 48V–58V DC rail from transient overvoltage events such as load dump or inductive kickback.

DO-214AA (SMB) package – footprint and storage

Supplied in a surface-mount SMB package. Store the reels dry – the SMB body is not hermetically sealed, and moisture sensitivity level should be confirmed from the original reel label before reflow.

Frequently asked questions

How can I order P6SMB68AT3 or check stock?

The P6SMB68AT3 is obsolete per onsemi. We do not hold stock but can source it through our independent distribution network. Submit an RFQ with your target quantity and we will confirm availability and pricing at quote time.

Is P6SMB68AT3 AEC-Q101 qualified?

Yes, the series is listed as Automotive, AEC-Q101. This qualification covers the temperature range -65°C to 150°C junction and the production lot traceability required for automotive applications.

What is the peak pulse power of P6SMB68AT3?

600W peak pulse power per the 10/1000µs waveform. The clamping voltage at that pulse is 92V max at 6.5A peak pulse current.
