BC846BPN-TPQ2

Overview

The BC846BPN-TPQ2 is a dual bipolar junction transistor (BJT) array manufactured by Micro Commercial Components. It integrates one NPN and one PNP transistor within a single SOT-363 surface-mount package. The device supports a maximum collector current of 100 mA and a collector-emitter voltage rating of 65 V. Key electrical characteristics include a DC current gain (hFE) range of 200 to 450, a transition frequency of 100 MHz, and a power dissipation capacity of 200 mW. The component operates reliably across a temperature range from -55°C to +150°C junction temperature.

Feature Summary

• Integrates complementary NPN and PNP transistors in a compact SOT-363 package to minimize board space.
• Features closely matched current gain characteristics between the two elements for balanced performance.
• Provides low collector-emitter saturation voltage to enhance switching efficiency.

Applications

• General-purpose signal amplification circuits
• Digital logic interface and switching applications
• Portable equipment requiring small form-factor components

Procurement Notes

Verify the specific suffix 'Q2' against official MCC documentation to confirm automotive qualification status or specific binning requirements. Ensure compatibility with standard SOT-363 footprints during PCB layout. Confirm RoHS compliance details through the manufacturer's latest datasheet before final procurement decisions.

Selection Notes

Select this component when a matched NPN/PNP pair is required for differential signaling or push-pull configurations. The SOT-363 package offers a smaller footprint compared to discrete dual packages. Ensure the design accounts for the 200 mW power dissipation limit and the 65 V voltage rating under worst-case operating conditions.

Part Context

This part belongs to the BC846 series of general-purpose silicon NPN/PNP transistors. It serves as a dual-element alternative to using separate discrete transistors, simplifying assembly and reducing component count. The BC846B variant specifically denotes a medium-gain classification suitable for a wide range of analog and digital applications.

Replacement Considerations

Direct substitutes include the BC846BPN from other manufacturers such as Nexperia or Panjit, provided they meet the same SOT-363 pinout and electrical specifications. Verify that any replacement maintains the 200-450 hFE gain range and identical thermal characteristics.
