Each transistor integrates a 10kΩ base resistor (R1) and a 47kΩ emitter-base resistor (R2), so the bias network is already on-chip. That eliminates two external resistors per channel — four components saved versus a discrete transistor pair. The part is rated for 50V collector-emitter breakdown and 100mA continuous collector current, with a transition frequency of 250MHz. ROHS3 compliant. ## SOT-363 footprint — fits tight layouts The UMT6 package is a 6-pin SOT-363 variant, roughly 2.0mm × 2.1mm. Surface-mount assembly with standard reflow profiles. The compact footprint suits multi-layer PCBs in portable devices, sensor modules, and space-constrained control boards. No special thermal management needed at the 150mW power ceiling in typical ambient conditions.","metaTitle":"UMH9NTN Dual NPN Pre-Biased Transistor, 50V, 100mA, SOT-363","metaDescription":"UMH9NTN dual NPN pre-biased transistor with integrated 10kΩ base and 47kΩ emitter resistors. 50V Vce, 100mA Ic, 250MHz fT.

The bias current changes with R1, so the two are not drop-in equivalents — the UMH9NTN's 10kΩ/47kΩ ratio gives a higher base-drive threshold, which matters in logic-level interface designs where the input voltage swing is limited."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/rohm/UMH9NTN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/rohm/UMH9NTN when reusing this data.
