Frequently Asked Questions

What applications is the BFG425W transistor suited for?

It can be used in RF front ends, wideband applications (like analog and digital cellular), radar detectors, pagers, satellite television tuners (SATV), and high frequency oscillators.

How much power can the collector dissipate under normal conditions?

The total power dissipation is rated at 135 mW when the junction temperature is below 103 °C.

What are the key performance metrics (High Frequency/Gain)?

It offers a very high power gain (-20 to -17 dB max) and has a high transition frequency ($f_T$), reaching up to 25 GHz.

How is this product packaged?

The transistor comes in a plastic, 4-pin dual-emitter SOT343R package.
