This part is qualified to AEC-Q101, so it carries the screening and temperature-range documentation required for automotive under-hood and chassis-domain electronics. ## 50 V breakdown, 100 mA continuous — what that buys you With a 50 V collector-emitter breakdown and 100 mA continuous collector current rating, this dual transistor handles typical automotive loads with headroom for load-dump transients. The 200 MHz / 250 MHz transition frequency (NPN / PNP respectively) supports PWM dimming or solenoid drive at several tens of kilohertz. ## Pre-biased — fewer passives, smaller board area The integrated 47 kΩ base and emitter-base resistors eliminate two external resistors per transistor channel. On a dense automotive ECU board where every 0603 or 0402 passive adds placement cost and failure risk, that matters. The 300 mV saturation voltage at 5 mA collector current (with 250 µA base drive) keeps conduction loss low enough that the 200 mW package power limit is rarely the constraint in a 12 V system. ## Sourcing and lifecycle The AEC-Q101 qualification means the documentation trail (PPAP, IMDS, etc.) is available for automotive BOM submissions.","metaTitle":"RN4904,LXHF(CT RN4904 LXHF(CT Dual Pre-Biased Transistor","metaDescription":"RN4904 LXHF(CT dual NPN/PNP pre-biased transistor, AEC-Q101 qualified, 50V Vce, 100mA Ic, 47kΩ bias resistors, US6 package.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q101","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Automotive, AEC-Q101","Package":"Tape & Reel (TR); Cut Tape (CT)","Power - Max":"200mW","Mounting Type":"Surface Mount","Package / Case":"6-TSSOP, SC-88, SOT-363","Transistor Type":"1 NPN, 1 PNP - Pre-Biased (Dual)","lifecycle_stage":"eol_hot","Resistor - Base (R1)":"47kOhms","Frequency - Transition":"200MHz, 250MHz","Supplier Device Package":"US6","Resistor - Emitter Base (R2)":"47kOhms","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":"80 @ 10mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.46","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.46000","currency":"USD"},{"qty":10,"price":"$0.33900","currency":"USD"},{"qty":100,"price":"$0.19210","currency":"USD"},{"qty":500,"price":"$0.12720","currency":"USD"},{"qty":1000,"price":"$0.09752","currency":"USD"},{"qty":3000,"price":"$0.08480","currency":"USD"},{"qty":6000,"price":"$0.07632","currency":"USD"},{"qty":15000,"price":"$0.06784","currency":"USD"},{"qty":30000,"price":"$0.06360","currency":"USD"},{"qty":75000,"price":"$0.06000","currency":"USD"}]},"links":{"datasheetUrl":"https://toshiba.semicon-storage.com/info/RN4904_datasheet_en_20210824.pdf?did=18954&prodName=RN4904","sourceUrl":null},"ai":{"faq":[{"question":"Is RN4904 AEC-Q101 qualified?","answer":"Yes, the RN4904 series is listed as Automotive, AEC-Q101.
