onsemi Dual NPN + PNP Bipolar Transistor 200 mA, 45 V, SOT-363, Surface Mount BC847BPDW1T3G

The onsemi BC847BPDW1T3G is a dual NPN and PNP bipolar transistor designed for reliable signal amplification and switching in compact electronic devices. This model integrates two complementary transistors within a single SOT-363 surface-mount package, making it ideal for use in densely populated printed circuit boards (PCBs) and automated SMT assembly lines.

With a maximum collector current rating of 200 mA, this component is suitable for a variety of low power amplification and digital switching applications, including signal processing, general analog circuits, and interface buffering in industrial control, instrumentation, and consumer electronics. The transistors offer a maximum collector-emitter voltage of 45 V, allowing operation in circuits with a wide voltage range while still maintaining device integrity even under occasional transients or high-side switching tasks.

The BC847BPDW1T3G features a compact package dimension of just 2.2 mm by 2.2 mm, and a height of 1.1 mm, minimizing the space required on a PCB. Its surface-mount (SMD) design supports reflow soldering and integration into automated assembly processes. The 6-pin SOT-363 form factor facilitates easy routing of input, output, and bias connections for both the NPN and PNP transistors housed within.

The device operates reliably across a broad temperature range from -55°C to +150°C, suiting it for applications exposed to varying ambient environments. The high transition frequency of 100 MHz ensures it can handle fast signal edges in digital or analog circuits, while a low maximum emitter-base voltage of 6 V and robust collector-base voltage of 50 V provide flexibility for circuit designers. The minimum DC current gain (hFE) of 200 ensures stable amplification characteristics across the specified operating range.

Power dissipation is rated up to 380 mW, making the BC847BPDW1T3G ideal for small-signal amplification without excessive heat buildup. Thanks to the combination of dual-transistor functionality, SOT-363 packaging, and its electrical ratings, this device is commonly used in signal conditioning, logic level translation, analog input protection, voltage level shifting, and as a driver component in various automation equipment, industrial controls, and commercial electronics.

Key applications include instrumentation amplifiers, analog switching, voltage inverters, and any design requiring complementary transistor pairs in compact, space-saving form. This device enables designers to shrink component count and streamline PCB layouts in space-sensitive applications. Overall, the BC847BPDW1T3G delivers dependable signal handling and efficient board utilization for modern electronic designs.
