UMF5NTR

The UMF5NTR is a dual pre-biased transistor array manufactured by ROHM Semiconductor, designed for space-constrained digital and analog switching applications. This component integrates one NPN pre-biased transistor and one PNP transistor into a single surface-mount package, simplifying circuit design by eliminating external base resistors. Each transistor includes an integrated 47kΩ resistor to ensure stable biasing and reliable switching performance.

Electrical characteristics include a maximum voltage rating of 50V and a nominal power dissipation of 150mW. The device supports collector currents up to 500mA and features a minimum DC current gain (hFE) of 68 at 5mA/5V, rising to 270 at 10mA/2V. Low saturation voltages of 300mV and 250mV under specified conditions contribute to efficient operation. The transition frequency ranges from 250MHz to 260MHz, making it suitable for moderate-speed switching tasks.

Housed in a UMT6 package, also known as 6-TSSOP, SC-88, or SOT-363, this component utilizes surface-mount technology for automated assembly. Its compact footprint and integrated biasing network make it ideal for portable electronics, consumer appliances, and industrial control boards where board space and component count must be minimized.
