It works across a 2.5V to 34V supply range, drawing only 125µA quiescent current — low enough to leave it powered continuously on a battery bus without noticeable drain. The 2.5V to 34V input range covers common rails like 3.3V, 5V, 12V, and 24V with margin. If your design runs on a 5V bus and you want to clamp off anything above, say, 5.5V, this part handles it without an external regulator. The 125µA supply current is the current the chip itself burns — not the load current — so it can sit on the input side of the protection FET and stay alive even when the output is disconnected. That matters for always-on protection in remote sensors or POE-powered devices where every microamp counts. ## Package and footprint notes 8-WFDFN exposed pad package (8-DFN 3x2 mm), surface mount. Operating temperature 0°C to 70°C. ## Lifecycle and sourcing posture For a repair bench or a production line filling a BOM line, this is a straightforward part to bring in without worrying about a sudden obsolescence surprise.","metaTitle":"LTC4365CDDB-1#TRMPBF Overvoltage Protection IC, 2.5V-34V","metaDescription":"LTC4365CDDB-1#TRMPBF overvoltage/undervoltage protection IC from Analog Devices. 2.5V to 34V supply, 125µA quiescent current, 8-DFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"Overvoltage, Undervoltage Protection","Mounting Type":"Surface Mount","Package / Case":"8-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"125µA","Voltage - Supply":"2.5V ~ 34V","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"8-DFN (3x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.84","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.84000","currency":"USD"},{"qty":10,"price":"$4.35100","currency":"USD"},{"qty":25,"price":"$4.11320","currency":"USD"},{"qty":100,"price":"$3.56480","currency":"USD"},{"qty":250,"price":"$3.38200","currency":"USD"},{"qty":500,"price":"$3.03464","currency":"USD"},{"qty":1000,"price":"$2.55934","currency":"USD"},{"qty":2500,"price":"$2.43137","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/77bf6cf901a065085e68381abc0e704a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the equivalents for LTC4365CDDB-1#TRMPBF?","answer":"The closest functional peer is the LTC4365CDDB#TRMPBF, which shares the same die and 8-DFN package but differs in the tape-and-reel suffix.
