Overview
The 2N6428 APM TIN/LEAD is a single NPN Darlington transistor manufactured by Central Semiconductor Corp. It utilizes silicon technology and is housed in a TO-92-3 through-hole package. Key electrical ratings include a collector-emitter voltage (VCEO) of 40 V, a collector-base voltage (VCBO) of 40 V, and an emitter-base voltage (VEBO) of 12 V. The device supports a continuous collector current of 500 mA with a power dissipation of 7.0 pF noted in specifications. It features a minimum DC current gain (hFE) of 20,000 at 5 V and 500 mA, and a transition frequency (fT) of 150 MHz. Operating temperatures range from -65°C to +150°C.
Feature Summary
- High DC current gain capability suitable for sensitive switching applications
- Robust thermal performance with extended operating temperature range
- Through-hole mounting configuration for standard PCB integration
Applications
- High-gain amplification circuits
- Power switching loads
- Driver stages for relays or motors
Procurement Notes
Verify the specific suffix designation against official datasheets to confirm lead composition and packaging type. Ensure the procurement channel provides valid traceability documentation. Confirm that the requested quantity aligns with manufacturer standard packing quantities to avoid partial reel issues. Cross-reference the part number with the latest Central Semiconductor product announcements to ensure availability status.
Selection Notes
Select this component when high current gain is required in a low-voltage application environment. The TO-92-3 package limits power handling compared to larger packages, so thermal management must be considered. Verify that the 40 V rating meets the circuit's maximum voltage requirements. Compare the 500 mA current limit against peak load demands to prevent overstress conditions during operation.
Part Context
This part belongs to the 2N6426 series family of NPN Darlington transistors produced by Central Semiconductor. It shares similar structural characteristics with other devices in the lineup but is distinguished by its specific voltage and gain parameters. The series is designed for general-purpose switching and amplification tasks where high input impedance and gain are critical factors in circuit design.
Replacement Considerations
Official substitutes within the same manufacturer line may include variants with adjusted voltage ratings. Verify pinout compatibility before substitution. Check if alternative manufacturers offer equivalent Darlington configurations with matching hFE and VCEO specifications.
