The DO-15 axial package (DO-204AC) is through-hole, which means it can be hand-soldered and replaced on a repair bench without hot air – a practical advantage for rework and field service. The 500W peak pulse rating is the energy the part can absorb in a single surge event. For a 150V rail, the 243V clamping voltage ensures the protected circuit sees no more than that during a transient – but the designer must verify the downstream components' voltage rating has margin above 243V. Bidirectional means a single device protects against both positive and negative surges, which saves board space compared to using two unidirectional diodes back-to-back.","metaTitle":"SA150CA TVS Diode – onsemi, 500W, Bidirectional, DO-15","metaDescription":"SA150CA from onsemi: 500W peak pulse power, 150V standoff, 243V clamping, bidirectional Zener TVS in DO-15 axial package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"onsemi","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-204AC, DO-15, Axial","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Base Product Number":"SA150","Operating Temperature":"-","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-15","Voltage - Breakdown (Min)":"167V","Voltage - Clamping (Max) @ Ipp":"243V","Voltage - Reverse Standoff (Typ)":"150V","Current - Peak Pulse (10/1000µs)":"2.1A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5fc0e2ff8bc3d36b3848520208d9d8d1.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/SA150CA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/SA150CA when reusing this data.
