That eliminates two resistor placements per channel from the pick-and-place bill — a clean trade when you need a handful of low-side switches or logic-level interface buffers and want to shrink the component count on a dense SMT board. Collector current is rated 100 mA maximum with a 50 V Vce breakdown, so this part handles relay coils, small solenoid valves, and LED strings within that load envelope. Saturation voltage is specified at 300 mV at 250 µA base current into 5 mA collector current, so the on-state drop stays predictable for low-voltage rails. The 500 nA collector cutoff maximum keeps leakage negligible at elevated temperatures. ## Package and footprint — USV (SOT-353) on a 5-pin land pattern The RN1702,LF comes in a 5-pin USV package, which maps to the common SOT-353 / SC-70-5 footprint. Surface-mount only, so it suits automated assembly lines. The LF suffix confirms ROHS3 compliance, no lead in the finish.","metaTitle":"Toshiba RN1702,LF Dual NPN Pre-Biased Transistor, 250 MHz","metaDescription":"Toshiba RN1702,LF dual NPN pre-biased transistor with 10kΩ base and emitter resistors. 250 MHz transition frequency, 100 mA collector current, 50 V breakdown.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Power - Max":"200mW","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Transistor Type":"2 NPN - Pre-Biased (Dual)","lifecycle_stage":"eol_hot","Resistor - Base (R1)":"10kOhms","Frequency - Transition":"250MHz","Supplier Device Package":"USV","Resistor - Emitter Base (R2)":"10kOhms","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":"50 @ 10mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.29","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.29000","currency":"USD"},{"qty":10,"price":"$0.20000","currency":"USD"},{"qty":100,"price":"$0.09780","currency":"USD"},{"qty":500,"price":"$0.08154","currency":"USD"},{"qty":1000,"price":"$0.05666","currency":"USD"},{"qty":3000,"price":"$0.04911","currency":"USD"},{"qty":6000,"price":"$0.04555","currency":"USD"},{"qty":9000,"price":"$0.03777","currency":"USD"},{"qty":30000,"price":"$0.03711","currency":"USD"},{"qty":75000,"price":"$0.03333","currency":"USD"},{"qty":150000,"price":"$0.02889","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/91e0e48a3e239b852fb034067a2abb6c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the RN1702 LF replacement or equivalent?","answer":"For a functional equivalent with different bias resistor values, the RN1908(T5L,F,T) uses 22kΩ base and 47kΩ emitter resistors in the same dual NPN pre-biased configuration and same 200 mW power rating.
