The 250 MHz transition frequency keeps edges clean for level shifting, relay drivers, or small-signal switching up into the low-MHz range. ## Package and board-fit — ES6 vs SOT-563 The 100 mW max power limits the continuous current per channel in free air; at 25 °C ambient, each transistor's 100 mA rating is achievable only with moderate duty cycle or adequate copper area on the collector pads. CT is for prototype or low-volume builds.","metaTitle":"Toshiba RN1904FE,LF(CT Dual NPN Pre-Biased, 100mA, 50V, ES6","metaDescription":"Toshiba RN1904FE,LF(CT dual NPN pre-biased transistor, 100mA Ic, 50V Vce, 100mW, ES6 package.

The RN1904FE uses the smaller ES6 (SOT-563) package rated at 100 mW max power, while the RN1904 comes in a larger package rated at 200 mW. If your board has the space and needs the extra thermal headroom, the RN1904 is the drop-in alternative; otherwise the FE variant saves PCB area."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/RN1904FELFCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/RN1904FELFCT when reusing this data.
