The BFR92AW,115 is a silicon NPN RF transistor manufactured by NXP USA Inc., housed in an SC-70 (SOT-323) surface-mount package. It features a maximum collector-emitter voltage of 15 V and a continuous collector current limit of 25 mA. The device supports a transition frequency up to 5 GHz and dissipates 300 mW of power at a soldering point temperature of 93 °C. DC current gain ranges from 65 to 135 at 15 mA and 10 V. Noise figures are typically 2 dB at 1 GHz and 3 dB at 2 GHz under optimized source impedance conditions.
Verify component authenticity through authorized channels as the part is discontinued. Confirm RoHS compliance status and check for available replacement options from NXP or alternative manufacturers. Ensure storage conditions remain within specified limits to maintain junction integrity before installation.
Evaluate thermal resistance requirements against the 190 K/W junction-to-soldering-point rating. Verify that the application bias points align with the specified 15 mA collector current for optimal gain and noise performance. Consider the 150 °C maximum junction temperature limit during high-power operation scenarios.
This component belongs to the BFR92 family of wideband transistors. It shares identical crystal structures with the SOT-23 packaged BFR92A variant. The device is designed specifically for high-frequency silicon applications requiring stable performance in compact form factors.
Publicly confirmed substitute part numbers include 2SC4713KT146R and BFP181E7764HTSA1.
