The ON5239,135 is an RF MOSFET manufactured by NXP USA Inc., designed for efficient radio frequency switching and amplification tasks. It is housed in a surface-mount SC-73 package, also identified as SOT223 in some documentation. This component serves as a discrete RF transistor suitable for applications requiring reliable high-frequency performance. The device is currently listed as no longer manufactured by the supplier.
Verify availability status carefully as this part is marked as no longer manufactured. Confirm exact package type (SC-73 or SOT223) against specific datasheet requirements before ordering. Check for tariff implications if shipping to the United States. Ensure replacement strategies are evaluated due to end-of-life status.
Select this component only if legacy compatibility with existing RF designs is required. Consider the surface-mount form factor for PCB integration. Evaluate alternative active components if new designs are being developed, given the discontinued manufacturing status of this specific NXP part number.
This RF MOSFET belongs to NXP's portfolio of discrete semiconductor devices. It is categorized under RF FETs and MOSFETs. The component supports radio frequency applications where compact surface-mount packaging is necessary for modern electronic assembly processes.
Public confirmed substitute part numbers are not available in the provided source material. Due to the discontinued status, engineering teams should consult official NXP channels for recommended cross-reference solutions or next-generation replacements.
