The UP0459900L is a dual NPN bipolar transistor array manufactured by Panasonic Electronic Components. It integrates two independent NPN transistors within a compact SOT-563 (SSMINI6-F1) surface-mount package. The device supports a maximum collector current of 50mA and 100mA for its respective internal transistors, with collector-emitter breakdown voltages rated at 20V and 50V. Key electrical characteristics include a transition frequency of 1.6GHz and 150MHz, minimum DC current gains of 25 and 160 at 2mA/10V, and a maximum power dissipation of 125mW.
Verify component authenticity through authorized Panasonic distributors or certified suppliers. Confirm the obsolete status of this specific part number before finalizing procurement plans. Ensure that the received units match the specified SOT-563 package and electrical parameters documented in official datasheets to prevent integration failures.
Select this component when a dual NPN configuration is required in a minimal footprint. Consider the 1.6GHz transition frequency for high-speed switching needs. Evaluate the 20V and 50V breakdown voltage limits against circuit requirements. Note the obsolete status may impact long-term supply availability.
This component belongs to Panasonic's discrete transistor lineup, specifically designed for integrated dual-transistor applications. It utilizes the SSMINI6-F1 package variant, which is optimized for automated surface-mount assembly processes. The part represents a specialized solution for compact electronic designs requiring multiple NPN elements.
Public confirmed substitute part numbers are not available in verified documentation. Due to the obsolete status, alternative sourcing requires careful evaluation of pin compatibility and electrical equivalence.
