It is specified for applications such as power supply pass elements, motor drive pre-drivers, and relay coil drivers where a single bipolar transistor handles moderate current and voltage. This is the preferred lifecycle stage for production BOMs that need supply continuity without obsolescence-driven redesign.","metaTitle":"2SD1818-AZ NPN Silicon Power Transistor, Active","metaDescription":"2SD1818-AZ NPN silicon power transistor in Bulk, active lifecycle.","metaKeywords":null},"attributes":{"series":"*","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":[],"specifications":{"Series":"*","Package":"Bulk","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5","stockQuantity":0,"priceTiers":[{"qty":601,"price":"$0.50000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0bc10d026f46bb3f1079312b3c6169de.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the best replacement for 2SD1818-AZ?","answer":"No official cross-reference or second-source alternate is listed for the 2SD1818-AZ.
