PUMB3 is a PNP double transistor with built-in bias resistor R1 (typ. 4.7 kΩ) produced by PHILIPS, widely used in general-purpose switching and amplification, inverter and interface circuits, circuit driver and other applications.
The Philips PUMB3 is a discrete semiconductor component consisting of two PNP transistors with a built-in bias resistor (R1 = 4.7 kΩ). This configuration simplifies circuit design by reducing the number of external components and board space, while preventing mutual interference between the transistors. The device is housed in a plastic SC-88 (SOT363) surface-mounted package.
