BC550BTAR

Single Bipolar Transistors Overview

The BC550BTAR is an NPN silicon epitaxial planar transistor manufactured by onsemi, housed in a TO-92 (TO-226AA) three-pin through-hole package. It features a maximum collector-emitter voltage of 45V and a continuous collector current rating of 100mA. The device offers a DC current gain (hFE) range of 110 to 800 at 2mA collector current. Key electrical parameters include a transition frequency of 300MHz, a collector cutoff current of 15nA, and a power dissipation capacity of 500mW. The component operates within a junction temperature range of -65°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing from distributors. Confirm RoHS compliance status as historical data varies by manufacturing date. Ensure the TO-92 pinout matches your PCB footprint requirements before integration. Cross-reference datasheets from authorized onsemi channels to validate current production status and parameter tolerances.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring moderate voltage handling with high current gain. The 45V rating suits general logic and analog interfaces. Consider the BC550C variant if higher minimum gain is required. Evaluate thermal management needs given the 500mW dissipation limit in small packages. Verify noise specifications against application sensitivity thresholds.
