Each transistor integrates a 4.7kΩ base resistor, so you can drive the base directly from a 3.3V or 5V logic output without an external resistor — handy for cleaning up a BOM on a relay driver, solenoid pre-drive, or general-purpose load switch. The 50V collector-emitter breakdown gives comfortable headroom on a 12V or 24V automotive rail, and the 100mA continuous collector current covers most signal-level switching. AEC-Q101 qualification means this part has passed the automotive stress tests: temperature cycling, high-temperature reverse bias, and humidity bias. It is rated for the under-hood and cabin environments where a standard commercial transistor would drift or fail. ## Package and footprint for the layout Housed in a SOT-563 (ES6) package, the RN4990FE,LXHF(CT is a small surface-mount part — about 1.6 mm × 1.6 mm. It is hand-solderable with a fine-tip iron and some flux, though a hot-air station is easier. The datasheet footprint is a standard SOT-563 land pattern; no special thermal pad needed at 100mW max power.","metaTitle":"RN4990FE,LXHF(CT Dual Pre-Biased Transistor, AEC-Q101, 50V","metaDescription":"RN4990FE,LXHF(CT automotive dual NPN/PNP pre-biased transistor in SOT-563. 50V Vce, 100mA Ic, AEC-Q101 qualified.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q101","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Series":"Automotive, AEC-Q101","Package":"Tape & Reel (TR); Cut Tape (CT)","Power - Max":"100mW","Mounting Type":"Surface Mount","Package / Case":"SOT-563, SOT-666","Transistor Type":"1 NPN, 1 PNP - Pre-Biased (Dual)","lifecycle_stage":"eol_hot","Resistor - Base (R1)":"4.7kOhms","Frequency - Transition":"250MHz, 200MHz","Supplier Device Package":"ES6","Vce Saturation (Max) @ Ib, Ic":"300mV @ 250µA, 5mA","Current - Collector (Ic) (Max)":"100mA","Current - Collector Cutoff (Max)":"100nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"120 @ 1mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.39","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.39000","currency":"USD"},{"qty":10,"price":"$0.29100","currency":"USD"},{"qty":100,"price":"$0.18130","currency":"USD"},{"qty":500,"price":"$0.12402","currency":"USD"},{"qty":1000,"price":"$0.09540","currency":"USD"},{"qty":2000,"price":"$0.08586","currency":"USD"},{"qty":4000,"price":"$0.08586","currency":"USD"},{"qty":8000,"price":"$0.08109","currency":"USD"},{"qty":12000,"price":"$0.07394","currency":"USD"},{"qty":28000,"price":"$0.06917","currency":"USD"},{"qty":100000,"price":"$0.06750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d451a7b637e9108344a6108d0fd21c3f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the RN4990FE AEC-Q101 qualified?","answer":"Yes, the RN4990FE is part of the Automotive, AEC-Q101 series, meaning it is qualified for automotive-grade stress and reliability testing."},{"question":"Can RN4990FE be used in a 50V circuit?","answer":"Yes.
