With a collector current rating of 100 mA and a Vce breakdown of 50 V, this part handles typical 24 V or 48 V signal-level loads — relay coils, LED indicators, logic-level interfacing — without needing a separate driver transistor. ## Switching speed and package reality The 250 MHz transition frequency means the internal capacitance charges fast enough for PWM up to a few MHz, but the real switching edge is limited by the bias resistor network and the load capacitance. At 10 mA collector current the minimum hFE is 80 — plenty of gain to saturate the transistor with a microcontoller GPIO through the 2.2 kOhm base resistor. The SOT-363 (UMT6) package is 2.0 x 2.1 mm with 0.65 mm pitch — a common footprint shared with many ROHM small-signal parts. The 150 mW power limit means you cannot run both channels at 100 mA simultaneously without staying under the thermal derating curve; for continuous duty, derate the collector current or use only one channel at full load.","metaTitle":"UMB10NTN ROHM Dual PNP Pre-Biased, 100mA, 50V, SOT-363","metaDescription":"UMB10NTN dual PNP pre-biased transistor, 100mA Ic, 50V Vce, 250MHz ft, SOT-363.
