That means each transistor channel arrives with its bias network already on-die — no external R1 or R2 needed, which cuts two resistors per channel from the BOM and shrinks the layout to a 2.0 mm × 2.1 mm footprint. The 250 MHz transition frequency keeps switching clean into the low-MHz range, adequate for PWM fan control or serial bus translation up to a few megahertz. ## Saturation voltage and gain at low current VCE(sat) is specified at 300 mV maximum with 500 µA base drive and 10 mA collector current — a typical operating point for driving an optocoupler LED or a small relay coil. The DC current gain minimum of 68 at 5 mA, 5 V means the part stays in saturation with modest base current, which matters when the drive comes from a GPIO pin with limited source capability. Off-state leakage is 500 nA maximum, low enough to avoid false triggering in high-impedance loads.","metaTitle":"UMH2NTN Dual NPN Pre-Biased Transistor, 50 V, 100 mA","metaDescription":"UMH2NTN dual NPN pre-biased transistor array from Rohm Semiconductor. 50 V VCEO, 100 mA IC, 250 MHz fT, 47 kΩ integrated resistors in SOT-363.","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":"150mW","Mounting Type":"Surface Mount","Package / Case":"6-TSSOP, SC-88, SOT-363","Transistor Type":"2 NPN - Pre-Biased (Dual)","lifecycle_stage":"eol_hot","Resistor - Base (R1)":"47kOhms","Frequency - Transition":"250MHz","Supplier Device Package":"UMT6","Resistor - Emitter Base (R2)":"47kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 500µA, 10mA","Current - Collector (Ic) (Max)":"100mA","Current - Collector Cutoff (Max)":"500nA","DC Current Gain (hFE) (Min) @ Ic, Vce":"68 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.48","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.48000","currency":"USD"},{"qty":10,"price":"$0.36200","currency":"USD"},{"qty":100,"price":"$0.22560","currency":"USD"},{"qty":500,"price":"$0.15434","currency":"USD"},{"qty":1000,"price":"$0.11872","currency":"USD"},{"qty":3000,"price":"$0.10685","currency":"USD"},{"qty":6000,"price":"$0.10091","currency":"USD"},{"qty":15000,"price":"$0.09201","currency":"USD"},{"qty":30000,"price":"$0.08607","currency":"USD"},{"qty":75000,"price":"$0.08400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/edef53eddd90916178e479a9ed2d61ad.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional equivalent to UMH2NTN?","answer":"The closest functional equivalent is the UMB2NTN, which is a dual PNP pre-biased transistor with the same 47 kΩ resistors, 50 V rating, 100 mA current, and SOT-363 package.
