The Central Semiconductor Corp 2N6426 APM PBFREE is a single NPN Darlington transistor housed in a TO-92-3 (TO-226AA) through-hole package. It features a collector-emitter voltage (VCEO) of 40 V and a collector-base voltage (VCBO) of 40 V, with an emitter-base voltage (VEBO) rating of 12 V. The device supports a continuous collector current of 500 mA and offers a minimum DC current gain (hFE) of 20,000 at 500 mA. It has a power dissipation capacity of 7.0 pF capacitance contextually linked to high-frequency performance, though specific Pd is not explicitly listed in the provided table, the series context implies standard low-power handling. The transition frequency (fT) is 150 MHz, operating within a temperature range of -65°C to +150°C.
Verify the exact manufacturer part number against the datasheet to ensure compatibility with the APM suffix requirements. Confirm RoHS compliance status as indicated by the PBFREE designation. Check lead times as production cycles may vary significantly from standard stock items. Ensure the TO-92-3 package dimensions match your PCB footprint constraints before finalizing procurement orders.
Select this component when high current gain is required in a small through-hole package. Compare the 40 V voltage ratings against circuit supply voltages to ensure adequate headroom. Consider the 150 MHz transition frequency for AC signal applications. Verify that the 500 mA current limit meets the load requirements without exceeding thermal dissipation limits in the intended enclosure.
This device belongs to the 2N6426 series of NPN Darlington transistors manufactured by Central Semiconductor. It is designed for general-purpose switching and amplification tasks where high beta values are critical. The TO-92-3 package provides a compact solution for low-to-medium power applications in consumer and industrial electronics.
