Rated for 100 mA continuous collector current with a 50 V collector-emitter breakdown, it handles typical logic-level loads like relay coils, LED indicators, or small signal switching where you want to eliminate external base resistors. The dual-transistor layout shares the emitter for both devices, common in BRT arrays for space-constrained boards. Available in tape-and-reel or cut-tape quantities for prototyping or production runs.","metaTitle":"Toshiba RN1705,LF dual NPN pre-biased transistor, 100mA, USV","metaDescription":"Toshiba RN1705,LF dual NPN pre-biased transistor, 100mA Ic, 50V Vce, 200mW, SOT-353 (USV).

The key difference is the base resistor R1: 2.2 kOhms on the RN1705 vs 10 kOhms on the RN1707. That changes the input threshold — the RN1705 turns on at a lower base current than the RN1707. If your circuit was biased for the 10 kOhm resistor, swapping in the 2.2 kOhm part may drive the transistor harder into saturation, so verify the base drive conditions first."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/RN1705LF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/RN1705LF when reusing this data.
