BC847BTT1

Overview

The BC847BTT1 is a single NPN silicon bipolar junction transistor manufactured by onsemi. It is housed in an SOT-23 (TO-236AB) surface-mount package. The device supports a maximum collector current of 100 mA and a collector-emitter voltage of 45 V. Key electrical parameters include a DC current gain (hFE) minimum of 200, a transition frequency of 100 MHz, and a power dissipation rating of 200 mW. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Single NPN configuration for general-purpose amplification and switching
• High DC current gain ensuring effective signal control
• Leadless ultra-small plastic package design for space-constrained applications

Applications

• General-purpose low-frequency signal amplification
• Digital logic level shifting circuits
• Switching applications in portable electronic devices

Procurement Notes

Verify the specific suffix TT1 against official onsemi documentation to confirm tape-and-reel packaging specifications. Ensure the order matches the exact part number to avoid confusion with similar variants like BC847BLT1G or BC847BT1G. Confirm RoHS compliance status through the manufacturer's latest material declaration before finalizing procurement.

Selection Notes

Select this component when a compact NPN transistor with moderate gain and voltage ratings is required. The SOT-23 package facilitates automated surface-mount assembly. Consider the 100 mA current limit and 45 V breakdown voltage during circuit design to ensure operation remains within safe limits under all expected load conditions.

Part Context

This part belongs to the BC847 series of small-signal NPN transistors. It serves as a complementary device to the PNP BC857 series. The BC847 family is widely utilized in consumer electronics due to its balance of performance, size, and cost-effectiveness in standard surface-mount configurations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative manufacturers such as Nexperia or Diotec only if their datasheets explicitly state pin-compatible equivalence and identical electrical characteristics.
