What are the key features of BC 846S?
- Dual NPN configuration with 65 V VCEO and 100 mA IC per transistor for space-efficient paired switching
- 6-pin SOT-363 SMD package integrates two independent transistors in a footprint smaller than two individual SOT-23 devices
- Common substrate integration ensures closely matched thermal behavior, ideal for differential amplifier and balanced switching circuits
What is BC 846S used for?
The BC 846S is used in portable consumer electronics, audio amplifiers, and signal processing circuits where two matched NPN transistors are needed in a minimal board footprint. Its 65 V breakdown voltage and 100 mA collector current handling suit LED driver arrays, relay drivers, and logic level shifting in mobile devices and wearables. The compact SOT-363 package is ideal for space-constrained PCB designs in smartphones, tablets, and IoT sensor nodes.

Frequently Asked Questions
What are the voltage and current limits for each transistor in the BC 846S?
Each NPN transistor in the BC 846S is rated for a collector-emitter voltage of 65 V and a maximum continuous collector current of 100 mA. These ratings suit low-power switching and amplification circuits operating from 3.3 V to 48 V supply rails in consumer and industrial electronics applications.
How does integrating two transistors in the BC 846S SOT-363 package benefit PCB layout?
The BC 846S places 2 NPN transistors in a single 6-pin SOT-363 package, occupying roughly half the board area of two separate SOT-23 transistors. This is highly advantageous in smartphone, tablet, and IoT PCB designs where board space is limited and 100 mA per channel switching is required.
Which circuit topologies gain the most from the matched NPN pair inside the BC 846S?
Differential amplifiers, push-pull LED drivers, and balanced switching circuits benefit most from the matched NPN pair in the BC 846S. The shared substrate ensures both transistors experience similar thermal conditions, improving DC bias stability in audio pre-amplifier stages and precision switching circuits handling up to 65 V.
