Product details

600W Zener TVS for 12V automotive rails

The AEC-Q101 qualification confirms it meets the stress and reliability requirements for under-hood and chassis-domain electronics.

Clamping voltage and pulse current

With a minimum breakdown voltage of 10.5V and a maximum clamping voltage of 15.6V at 38A peak pulse current, this part holds the protected rail below typical 12V-system transient immunity thresholds. The 1550pF capacitance at 1MHz is high enough to load high-speed data lines — keep this part on power inputs, not signal pins.

onsemi lists the P6SMB11AT3 as Obsolete. The DO-214AA (SMB) package is surface-mount, tape-and-reel packaged. Confirm the date code and moisture sensitivity level with the supplier before reflow.

Frequently asked questions

How can I order P6SMB11AT3 or check availability?

The P6SMB11AT3 is obsolete per onsemi. No factory stock exists. We source it through independent distribution — submit an RFQ with your target quantity and we will quote availability and current pricing.

What is the replacement for P6SMB11AT3?

onsemi does not list a direct successor for the P6SMB11AT3. For a current-production alternative, look at onsemi's P6SMB series parts with similar voltage ratings, or consider the SZP6SMB series (also AEC-Q101). Verify the breakdown and clamping voltages match your protection threshold before swapping.
