UNRF2A300A

Overview

The UNRF2A300A is a silicon NPN epitaxial planar transistor with built-in resistors, designed for digital circuits. It features an ML3-N2 leadless package measuring 1.0 mm by 0.6 mm with a maximum height of 0.4 mm. The device supports a collector-emitter voltage of 50 V and a collector current of 80 mA. Internal biasing includes two 47 kΩ resistors with a ratio of 1.0. Key electrical characteristics include a forward current transfer ratio (hFE) of 80 at 5 mA, a transition frequency (fT) of 150 MHz, and a total power dissipation of 100 mW.

• Office equipment
• Communications equipment
• Measuring instruments
• Household appliances

Procurement Notes

Verify component status via official Panasonic channels before procurement. This product falls under maintenance or discontinued lifecycle stages. Confirm availability and latest specifications directly with sales staff to ensure compliance with current standards and avoid obsolescence risks during production planning.

Selection Notes

Select this component for applications requiring compact digital switching with integrated biasing. Ensure operating conditions remain within absolute maximum ratings, particularly regarding transient states like power-on. Verify suitability for standard electronic equipment; consult manufacturer for specialized automotive or life-support applications.

Part Context

The UNRF2A300A belongs to the UNRF series of transistors with built-in resistors manufactured by Panasonic Electronic Components. These devices are engineered to simplify circuit design by integrating base and emitter resistors, thereby reducing external component count and board space in high-density mounting scenarios.

Replacement Considerations

Consult official Panasonic documentation for verified substitute part numbers. Cross-referencing with similar models such as UNRF2A1 or UNRF2A2 may be necessary, but only confirmed substitutes listed in official catalogs should be utilized to maintain performance specifications.
