The onsemi 2N5401RLRM is a discontinued PNP silicon small-signal transistor housed in a TO-92 (TO-226AA) through-hole package. It features a maximum collector-emitter voltage of 150 V and a continuous collector current of 600 mA. The device provides a DC current gain (hFE) ranging from 50 to 240 at specific test conditions, with a transition frequency (fT) between 100 MHz and 300 MHz. Total power dissipation is rated at 625 mW at 25°C ambient temperature. Operating junction temperatures span from -55°C to +150°C.
Verify component obsolescence status prior to design finalization. Confirm availability of alternative packaging or equivalent replacement devices from the manufacturer. Ensure procurement channels provide authentic components matching the specified datasheet parameters. Review environmental compliance documentation for legacy production runs.
Select this component for designs requiring high-voltage PNP switching or amplification within standard through-hole constraints. Evaluate thermal management requirements against the 625 mW dissipation limit. Compare electrical characteristics such as hFE and fT against circuit requirements to ensure adequate performance margins under varying operating temperatures.
