That means you drop the two external resistors per transistor that a standard NPN pair would need — four components saved on the bill of materials. The bias network sets a defined off-state and a predictable turn-on threshold, so the part works as a simple switch or inverter without extra biasing circuitry. ## Switching performance and drive requirements Collector current is rated to 100 mA continuous, with a Vce breakdown of 50 V — enough for 5 V or 12 V logic-level loads, relay drivers, or LED strings. The transition frequency of 250 MHz indicates the internal die can switch fast, but the built-in resistors limit the base drive; expect practical switching speeds in the low-MHz range for saturated operation. Vce(sat) is specified at 300 mV maximum with 250 µA base drive into 5 mA collector current, so the voltage drop stays low in lightly loaded digital outputs or level shifters. ## Lifecycle — active, no last-time-buy concerns ROHM lists the UMG11NTR with an active product status.","metaTitle":"UMG11NTR Dual NPN Pre-Biased Transistor, 50V, 100mA, UMT5","metaDescription":"UMG11NTR 2 NPN pre-biased transistor pair in UMT5 package. 50V Vce, 100mA Ic, 150mW.
