Applications
The BC 807U is commonly used in load switch circuits, push-pull signal amplifiers, and complementary driver stages in consumer electronics, portable devices, and industrial control systems. Its dual PNP structure in a single SC-74 package makes it efficient for differential pair amplifiers, LED drive circuits, and relay driver stages where two same-polarity transistors are required in close proximity. The 45 V, 500 mA ratings also serve motor control pre-driver and inductive load switching applications in space-constrained PCB designs.

Frequently Asked Questions
What are the maximum voltage and current ratings for each transistor in the BC 807U?
Each transistor in the BC 807U has a maximum collector-emitter voltage (VCEO) of 45 V and a continuous collector current (IC) of 500 mA. With two independent PNP elements in one 6-pin SC-74 package, designers can build complementary or differential switching stages without sourcing two separate discrete transistors, reducing both BOM cost and PCB footprint.
Which switching and amplification topologies benefit most from the BC 807U dual PNP configuration?
The BC 807U is well-suited for push-pull amplifier stages, LED driver arrays, relay switching circuits, and H-bridge motor pre-drivers. Its 45 V VCEO withstands inductive kickback from small motors and relays, while the 500 mA IC supports loads in portable consumer electronics and industrial sensor interfaces. The dual structure halves discrete component count for two-transistor topologies compared to using individual BC807 devices.
How much PCB area does the BC 807U SC-74 package save compared to two separate SOT-23 transistors?
The 6-pin SC-74 package of the BC 807U integrates two independent 45 V, 500 mA PNP transistors in a footprint only marginally larger than a single 3-pin SOT-23 device. Replacing two separate BC807 transistors with one BC 807U saves approximately 50% of board area for the transistor pair, a meaningful gain for high-density IoT boards, wearables, and portable medical devices.
