SS9018FBU

Overview

The SS9018FBU is an NPN epitaxial silicon bipolar RF transistor manufactured by Fairchild Semiconductor, now under onsemi. Designed for high-frequency applications, it operates up to a frequency of 1.1 GHz. The device features a maximum collector-emitter voltage (VCEO) of 15 V and a maximum continuous collector current of 50 mA. It has a power dissipation rating of 400 mW and is housed in a TO-92-3 through-hole package. The minimum DC current gain (hFE) is specified at 54.

Feature Summary

NPN epitaxial silicon construction optimized for radio frequency signal processing
Operational capability extending to 1.1 GHz for high-speed switching and amplification
Through-hole TO-92-3 packaging suitable for standard board mounting

Applications

AM/FM amplifier circuits
Local oscillator stages in FM/VHF tuners
General-purpose RF signal processing

Procurement Notes

This component is officially classified as obsolete and is no longer in production by the manufacturer. Verification of availability should focus on distributor surplus or secondary market sources rather than direct factory orders. Confirm RoHS compliance status and specific lot dates when sourcing from non-primary channels, as production end-of-life documentation may limit warranty support.

Selection Notes

Engineers selecting this part must account for its discontinued status and potential supply chain constraints. The 15 V collector-emitter voltage and 50 mA current limits define the operational envelope for RF tasks. Consider the transition from Fairchild to onsemi branding when reviewing updated datasheets or replacement components within the same family.

Part Context

The SS9018 series belongs to the broader category of discrete semiconductor RF transistors produced by Fairchild Semiconductor. This specific model represents the NPN variant designed for low-power, high-frequency operations. It is distinct from other series members like the PNP SS9012, sharing similar physical form factors but differing in polarity and specific electrical characteristics.
