Overview
The Central Semiconductor Corp 2N6426 APP TIN/LEAD is an NPN Darlington transistor housed in a TO-92-3 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 dissipates power up to 7.0 pF capacitance contextually associated with its switching profile. Its transition frequency (fT) reaches 150 MHz, ensuring adequate bandwidth for high-speed applications.
Feature Summary
- High DC current gain capability with a minimum hFE of 20,000 at 5 V and 500 mA.
- Robust voltage handling with 40 V ratings for both collector-emitter and collector-base configurations.
- Optimized for high-frequency performance with a 150 MHz transition frequency.
Applications
- High-gain amplification stages requiring significant current drive.
- Switching circuits operating within moderate voltage limits.
- Driver stages for relays or low-power loads.
Procurement Notes
Verify the specific suffix 'APP TIN/LEAD' against official datasheets to confirm lead composition and packaging type. Ensure the ordering quantity aligns with manufacturer minimums, typically multiples of 2000 units in ammo pack configuration. Confirm RoHS compliance status directly with the manufacturer as specifications may vary by production batch.
Selection Notes
Select this component when high current gain is critical for driving subsequent stages without intermediate buffering. The TO-92-3 package suits prototyping and low-volume through-hole designs. Consider the 40 V limit carefully; higher voltage requirements necessitate alternative part numbers within the Central Semiconductor portfolio.
Part Context
This part belongs to the Central Semiconductor Darlington transistor series, designed for general-purpose switching and amplification. The 2N6426 designation indicates a standardized NPN configuration. The tin/lead finish suggests compatibility with traditional soldering processes, distinct from lead-free variants often marked differently in distributor catalogs.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameters before considering any generic Darlington alternatives.
