Each transistor is rated for a collector-emitter breakdown of 50 V and a continuous collector current of 150 mA, with a total package power dissipation of 150 mW. The NPN side transitions at 180 MHz, the PNP at 140 MHz, making this part suitable for general-purpose switching, signal amplification, and level shifting in compact, low-power designs. The 50 V VCEO and 150 mA IC limits define the usable operating region for switching loads like small relays, LEDs, or logic-level signals up to 12 V or 24 V rails. The 150 mW package power cap means the total dissipation across both transistors must stay under that limit — if one side runs at 100 mW, the other is budgeted only 50 mW. For continuous duty near the current limit, derate the power or check the on-state voltage drop: VCE(sat) is 400 mV (NPN) and 500 mV (PNP) at 50 mA, so at 150 mA the actual dissipation per transistor can exceed 75 mW, leaving little headroom for the other die. ## Transition frequency and gain — signal-path fit With an ft of 180 MHz (NPN) and 140 MHz (PNP), this part can handle audio-frequency amplification, sensor buffering, and switching up to a few megahertz without significant gain roll-off. The minimum DC current gain (hFE) is 120 at 1 mA, 6 V — a solid baseline for small-signal driver stages. The collector cutoff current is only 100 nA (ICBO), which keeps leakage negligible in high-impedance nodes or battery-powered circuits. ## Package and footprint — design-in note The supplier device package is UMT6 (Rohm's own designation for the 6-pin SOT-363 footprint). It is a surface-mount package with a 1.25 mm body width and 0.65 mm pin pitch — typical for compact consumer, IoT, and portable equipment PCBs. The operating temperature range is rated up to 150 °C junction, so the part can sit near warm components or in enclosed modules as long as the 150 mW power budget is respected. ## Lifecycle and sourcing The laser etch and date-code traceability should match ROHM's factory markings for the UMT6 package — any mismatch in font or logo geometry warrants a decap/X-ray check before accepting a non-franchised lot.","metaTitle":"UMZ1NTR NPN/PNP Transistor, 50V 150mA, SOT-363, Active","metaDescription":"UMZ1NTR dual NPN/PNP transistor, 50V VCEO, 150mA IC, 180/140MHz ft, SOT-363 package.
