BC547_J61Z

Single Bipolar Transistors Overview

The BC547_J61Z is an NPN silicon small-signal transistor manufactured by onsemi, housed in a TO-92 (TO-226AA) three-pin through-hole package. It features a maximum collector current of 100 mA and a collector-emitter voltage rating of 45 V. The device supports a transition frequency of 300 MHz and a maximum power dissipation of 500 mW. DC current gain (hFE) ranges from 110 to 800 depending on the specific binning suffix.

Single Bipolar Transistors Procurement Notes

Verify the exact hFE binning associated with the J61Z suffix against the manufacturer's datasheet before procurement. Confirm RoHS compliance status as it varies by production batch. Ensure the TO-92 lead form matches the target PCB footprint requirements.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with moderate voltage ratings and high current gain is required. Compare the specific gain range of the J61Z variant against circuit biasing requirements. Consider thermal management if operating near the 500 mW power limit.

Single Bipolar Transistors Part Context

This part belongs to the widely used BC547 series of NPN general-purpose transistors. It serves as a complement to the PNP BC557 device. The series is standardized across multiple manufacturers including onsemi and NXP, ensuring broad industry compatibility for replacement and design purposes.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include BC547B and BC547C variants from onsemi or NXP. Cross-manufacturer equivalents such as 2N3904 may be considered if voltage ratings align with specific application needs.
