NE85639-T1-A

Overview

The NE85639-T1-A is an NPN silicon RF bipolar transistor manufactured by CEL. It operates at frequencies up to 6.5 GHz with a noise figure of 1.1 dB. The device is supplied in a surface-mount SOT-343 package and is marked as obsolete or end-of-life status.

Feature Summary

Designed for low-noise radio frequency amplification applications
Utilizes silicon technology for stable high-frequency performance

Applications

Low noise amplifier stages in RF circuits
Signal processing in wireless communication systems

Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or secondary market sources, as standard procurement channels may not support new orders.

Selection Notes

Engineers should evaluate alternative active components due to the obsolescence status. Selection must account for potential supply chain constraints and verify that substitute devices meet the original 6.5 GHz frequency and 1.1 dB noise figure requirements.

Part Context

The NE85639-T1-A is functionally equivalent to the 2SC4093-A variant from CEL. Both parts share identical electrical specifications and are classified under RF bipolar transistors. The T1 suffix typically indicates tape-and-reel packaging for automated assembly.
