The 200 MHz transition frequency means it can handle moderate-speed switching in DC-DC converters or signal paths without introducing phase lag.
Saturation voltage and gain — sizing the drive margin
The 300 mV maximum Vce saturation at 500 µA base drive and 10 mA collector current keeps conduction losses low — useful when the load current is a few milliamps and the logic output can only source a few hundred microamps. The 100 nA collector cutoff current ensures negligible leakage in the off state at room temperature.
Active lifecycle — no last-time-buy concern
There is no imminent end-of-life or last-time-buy risk for new designs.
