The single bidirectional channel replaces two unidirectional diodes in series, saving board space and reducing part count on the BOM. ## Through-hole DO-15 axial package — what it means for assembly Housed in the DO-204AC (DO-15) axial-lead package, the P6KE51CA-T is a through-hole part — it inserts into plated through-holes and is wave-soldered, not reflowed. Available in Tape & Reel (TR) or Cut Tape (CT) formats, the TR variant feeds into axial-tape feeders for automated insertion; the CT option suits prototype or low-volume builds where hand-insertion is acceptable. ## Obsolete — sourcing through independent channels No official successor order code is recorded from the manufacturer. A functionally equivalent replacement would need matching 600W peak pulse power, 43.6 V standoff, bidirectional polarity, and DO-15 package — any substitution requires board-level validation of the clamping voltage and surge current profile.","metaTitle":"P6KE51CA-T Diodes Inc Zener TVS, 600W, DO-15, Obsolete","metaDescription":"Diodes Inc P6KE51CA-T bidirectional Zener TVS, 600W peak pulse, 43.6V standoff, DO-15 axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Diodes Incorporated","Type":"Zener","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-204AC, DO-15, Axial","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"600W","Base Product Number":"P6KE51","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-15","Voltage - Breakdown (Min)":"48.5V","Voltage - Clamping (Max) @ Ipp":"70.1V","Voltage - Reverse Standoff (Typ)":"43.6V","Current - Peak Pulse (10/1000µs)":"8.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8069264fd616209624e252e56a5326bb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to P6KE51CA-T?","answer":"No official successor or pin-compatible cross-reference is recorded from Diodes Incorporated.
