The bidirectional configuration protects both polarities with a single device, simplifying layout on a 23.1 V rail where reverse-voltage events are possible. Capacitance is 370 pF at 1 MHz – a consideration for high-speed signal lines where added capacitive loading may affect signal integrity. ## Clamping voltage and peak current – 37.5 V at 16 A The maximum clamping voltage of 37.5 V at 16 A peak pulse current defines the voltage the protected circuitry must survive during a transient event. For a 23.1 V nominal rail, this provides a 14.4 V headroom above the working voltage. The breakdown voltage range starts at 25.7 V minimum, ensuring the device begins conducting before the rail exceeds safe limits.","metaTitle":"P6SMB27CAT3 onsemi Zener TVS – Obsolete, AEC-Q101","metaDescription":"P6SMB27CAT3 from onsemi: 600W peak pulse, 23.1V standoff, bidirectional Zener TVS in DO-214AA.

We can source it through independent distribution – submit an RFQ with your target quantity and we will confirm current availability and pricing at quote time."},{"question":"What is the replacement for P6SMB27CAT3?","answer":"onsemi has not published an official successor for this order code. For a drop-in functional equivalent, look at the P6SMB series with the same standoff voltage (23.1 V) and bidirectional configuration in DO-214AA – confirm the breakdown and clamping specifications match your design. We can help cross-reference against your BOM."},{"question":"What is the difference between P6SMB27CAT3 and SMBJ27CA?","answer":"Both are bidirectional Zener TVS diodes in DO-214AA with a 23.1 V standoff. The P6SMB27CAT3 is AEC-Q101 qualified (automotive grade) and rated for 600 W peak pulse, while the SMBJ27CA is typically a commercial-grade part rated for 600 W as well. The key delta is the automotive qualification – the P6SMB27CAT3 carries documented AEC-Q101 reliability data that the SMBJ27CA may lack."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/P6SMB27CAT3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/P6SMB27CAT3 when reusing this data.
