BC848AWT1

Overview

The BC848AWT1 is a single NPN silicon small-signal bipolar junction transistor manufactured by onsemi. It is housed in the SOT-323 surface-mount package, designed for low-power applications. The device supports a maximum continuous collector current of 100 mA and offers a collector-emitter breakdown voltage of 30 V. Key electrical characteristics include a minimum DC current gain (hFE) of 110 at specified test conditions and a transition frequency of 100 MHz. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• NPN epitaxial planar silicon construction optimized for general-purpose amplification
• SOT-323 surface-mount package design intended for low-power applications
• High DC current gain suitable for signal processing tasks

Applications

• General purpose amplifier circuits
• Switching applications requiring low power consumption
• Signal conditioning in consumer electronics

Procurement Notes

Verify the specific hFE binning code associated with the BC848AWT1 suffix against the official onsemi datasheet, as gain ranges vary across the BC848 series. Confirm that the SOT-323 package dimensions match the target PCB footprint requirements. Ensure compliance with RoHS directives if required by the end product specifications before finalizing procurement.

Selection Notes

Select this component when a compact NPN transistor with moderate gain and 30V rating is needed for space-constrained designs. Compare the 100 mA current limit and 100 MHz bandwidth against circuit requirements. Consider alternative packages like SOT-23 if higher thermal dissipation is necessary, or different hFE bins if precise gain control is critical for the application.

Part Context

This part belongs to the BC848 family of general-purpose NPN transistors from onsemi. The 'A' designation typically indicates a specific DC current gain range, while 'WT1' denotes the SOT-323 packaging and tape-and-reel shipping configuration. This series is widely used in portable devices and battery-operated equipment due to its small form factor and efficiency.

Replacement Considerations

Compatible substitutes include BC848ALT1G and BC848BWT1 from onsemi, which share similar electrical profiles but may differ in gain binning. Cross-manufacturer equivalents such as those from Diotec or LRC are available but require verification of pinout compatibility and exact parameter matching.
