The collector is on the backside paddle for thermal dissipation; ensure the PCB land pattern has a thermal via under the pad to keep junction temperature within the 150°C (TJ) limit. 230mW max power means this is a small-signal device, not a driver or power stage.
Active lifecycle status with ROHS3 compliance. No end-of-life notice or last-time-buy schedule is in effect. No official replacement or second-source alternate is listed in the product record.
The gain is 15.5dB to 18.5dB, specified across the operating bias and frequency range.
The device is supplied in a SOT-343F surface-mount package, with the supplier device package designated as 4-DFP. It is available in Tape & Reel (TR) or Cut Tape (CT) options.
