That means one component replaces two discrete transistors plus four resistors, which shrinks the pick-and-place count and frees up board area in a tight layout. The emitter-coupled pair configuration is handy for differential line receivers, current mirrors, or any low-side switch pair where you want matched Vbe tracking. ## 50 V, 100 mA — sizing the load With a 50 V collector-emitter breakdown and 100 mA continuous collector current, this part fits 12 V, 24 V, and even 48 V industrial logic rails as long as the load stays under 100 mA. The 250 MHz transition frequency means it switches fast enough for PWM drive up to a few megahertz — plenty for relay coils, LED strings, or signal-level gate drive. ## SOT-553 — tiny footprint, careful assembly The SOT-553 package is about 1.6 mm × 1.6 mm, which is small enough to fit under a BGA shadow or on a cramped sensor module. The trade-off is that hand-soldering is impractical — you want a reflow profile matched to the package. The ESV supplier device package code tells you the die attach and wire bond variant Toshiba uses internally; for footprint purposes, stick to the SOT-553 land pattern in the datasheet.","metaTitle":"Toshiba RN1709JE(TE85L,F) dual NPN pre-biased transistor","metaDescription":"Toshiba RN1709JE(TE85L,F) dual NPN pre-biased transistor pair with integrated 47kΩ base and 22kΩ emitter-base resistors. 50V Vce, 100mA Ic, 250MHz ft.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Power - Max":"100mW","Mounting Type":"Surface Mount","Package / Case":"SOT-553","Transistor Type":"2 NPN - Pre-Biased (Dual) (Emitter Coupled)","lifecycle_stage":"eol_hot","Resistor - Base (R1)":"47kOhms","Frequency - Transition":"250MHz","Supplier Device Package":"ESV","Resistor - Emitter Base (R2)":"22kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 250µA, 5mA","Current - Collector (Ic) (Max)":"100mA","Current - Collector Cutoff (Max)":"500nA","DC Current Gain (hFE) (Min) @ Ic, Vce":"70 @ 10mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.41","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.41000","currency":"USD"},{"qty":10,"price":"$0.30500","currency":"USD"},{"qty":100,"price":"$0.17290","currency":"USD"},{"qty":500,"price":"$0.11448","currency":"USD"},{"qty":1000,"price":"$0.08777","currency":"USD"},{"qty":2000,"price":"$0.07632","currency":"USD"},{"qty":4000,"price":"$0.07632","currency":"USD"},{"qty":8000,"price":"$0.06869","currency":"USD"},{"qty":12000,"price":"$0.06106","currency":"USD"},{"qty":28000,"price":"$0.05724","currency":"USD"},{"qty":100000,"price":"$0.05400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/da887b15388791d0b027b7790ddbf91d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between RN1709JE and RN1709?","answer":"The RN1709JE is the SOT-553 package variant; the base RN1709 typically comes in a larger package such as SOT-23 or SOT-323.
