It's rated for a collector-emitter breakdown of 65 V and a continuous collector current of 100 mA, with a power dissipation ceiling of 330 mW. The 250 MHz transition frequency and a minimum DC current gain of 200 at 2 mA collector current make it a solid choice for low-power switching and amplification roles — think signal conditioning, relay drivers, or logic-level translation on a mixed-voltage board. ## 65 V Vceo and 100 mA Ic — the operating envelope The 65 V collector-emitter breakdown gives you headroom for 24 V or even 48 V industrial rails, though you're limited to 100 mA continuous collector current. That combination — 65 V and 100 mA — is typical for the BC846 family and suits it for driving small relays, LEDs, or as a pre-driver for a larger MOSFET. The 330 mW power limit means you'll want to check the thermal derating if you're running near the current limit at elevated ambient temperatures; in a SOT-23 package, that's a practical constraint. ## Gain and frequency — what the 250 MHz fT means With a minimum hFE of 200 at 2 mA and 5 V, this transistor offers strong gain for a small-signal device, which is useful when the driving source is weak — a microcontroller GPIO pin, for instance. The 250 MHz transition frequency means it can handle switching up into the low-MHz range, so it's fine for PWM dimming or basic oscillator circuits, though it's not a dedicated RF transistor. The 15 nA maximum collector cutoff current is low enough not to leak into your bias network at room temperature. If you're qualifying it for a new design, you're not picking a part that's about to vanish.","metaTitle":"Infineon BC846BB5000 NPN Transistor, 65 V, 100 mA, SOT-23-3","metaDescription":"Infineon BC846BB5000 NPN transistor: 65 V Vceo, 100 mA Ic, 250 MHz fT, hFE min 200.
