2N6428 TIN/LEAD

Single Bipolar Transistors Overview

The Central Semiconductor Corp 2N6428 TIN/LEAD is a single NPN Darlington transistor designed for through-hole mounting in TO-92-3 packages. 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 maximum continuous collector current of 500 mA and dissipates up to 7.0 pF of capacitance. Key electrical characteristics include a minimum DC current gain (hFE) of 20,000 at 5 V and 500 mA, and a transition frequency (fT) of 150 MHz.

Single Bipolar Transistors Feature Summary

• High DC current gain capability suitable for sensitive switching applications
• Robust emitter-base voltage rating providing enhanced reverse bias protection
• Through-hole construction compatible with standard TO-92-3 board layouts

Single Bipolar Transistors Applications

• High-gain amplification stages requiring minimal base drive current
• Solid-state relay driver circuits
• Power switching loads controlled by low-current logic signals

Single Bipolar Transistors Procurement Notes

Verify the specific plating suffix required for your assembly process. The TIN/LEAD designation indicates tin-lead terminal finish, which differs from lead-free alternatives. Confirm RoHS compliance status and manufacturing origin details directly with authorized distributors or Central Semiconductor before finalizing procurement orders to ensure material specification alignment.

Single Bipolar Transistors Selection Notes

Select this component when high current gain is critical for driving moderate loads from weak control signals. The 40 V rating limits suitability for higher voltage power rails. Compare against standard BJT options if lower gain but higher speed is preferred. Ensure thermal management accounts for the TO-92-3 package dissipation limits under continuous load conditions.

Single Bipolar Transistors Part Context

This part belongs to the Central Semiconductor Darlington transistor family, specifically engineered as a legacy replacement for discontinued industry-standard devices. The manufacturer maintains production of such components to support long-term equipment maintenance without requiring circuit redesigns. This specific model serves as a direct functional equivalent for various industrial and commercial hardware systems.

Single Bipolar Transistors Replacement Considerations

Consult Central Semiconductor's official cross-reference documentation for verified substitute part numbers. Do not assume pinout compatibility with other NPN transistors lacking Darlington configurations. Verify that alternative devices match the 40 V voltage ratings and 500 mA current capacity requirements.
