Procurement Notes
Verify component status before procurement as the manufacturer has classified all devices in the SOT-523 package as End of Life (EOL). Orders may be accepted only if inventory is available or through Last Time Buy provisions. Contact Central Semiconductor Customer Service directly to confirm availability and specific ordering requirements for this discontinued part number.
Selection Notes
Select this component for designs requiring an NPN RF transistor in a compact SOT-523 footprint. Ensure the application operates within the specified 20 V collector-base voltage and 50 mA continuous collector current limits. Consider the thermal resistance of 500 °C/W when designing heat dissipation strategies for the surface mount package.
Part Context
This component belongs to the ULTRAmini™ series of surface mount transistors produced by Central Semiconductor Corp. The 'TR' suffix indicates tape and reel packaging, while 'PBFREE' denotes lead-free plating compliance. The marking code for identification on the package is HC7.
Replacement Considerations
No suggested replacement part numbers are provided by the manufacturer for the CMUT5179 BK or CMUT5179 TR variants. Customers are advised to contact Central Semiconductor Customer Service for assistance in locating alternate sources.
