The base product number is P6SMB, and the P6SMB series includes many active 600W TVS variants in the same DO-214AA package. If your design can tolerate a different standoff voltage or clamping level, a current P6SMB part may drop in without a board change — but the 27A suffix (25.7V breakdown, 23.1V standoff) is unique to this code. ## Package and mounting — DO-214AA SMB footprint The SMB footprint is standard — the same pad layout used by the SMCJ and SMBJ families — so a board already laid out for a 600W SMB TVS accepts this part without a layout change. The 700pF capacitance at 1MHz is typical for a 600W Zener TVS — it adds about 5-10pF to the line capacitance, negligible for 1MHz signal integrity but worth noting if the protected line is a high-speed data bus.","metaTitle":"P6SMB27AT3 onsemi Zener TVS Diode, 600W, AEC-Q101, DO-214AA","metaDescription":"P6SMB27AT3 onsemi Zener TVS, 600W peak pulse, 23.1V reverse standoff, AEC-Q101 automotive grade.

We source it through independent distribution — submit an RFQ with your target quantity and we will confirm availability and current pricing at quote time. No stock-holding claim; availability is confirmed per order."},{"question":"Is P6SMB27AT3 equivalent to P6SMB27A?","answer":"The P6SMB27A is the base device in the same series — same 27V breakdown class, same DO-214AA package. The 'T3' suffix on P6SMB27AT3 indicates a specific tape-and-reel packaging variant. Electrically they are identical; the T3 suffix is a packaging code, not a parametric change."},{"question":"Can I use P6SMB27AT3 in automotive applications?","answer":"Yes — the series is explicitly rated Automotive, AEC-Q101. The -65°C to 150°C junction temperature range covers under-hood and chassis environments.
