2SD1899-K-TP

Single Bipolar Transistors Overview

The MCC 2SD1899-K-TP is an NPN silicon epitaxial transistor in a DPAK (TO-251) package. It supports up to 3.0A collector current and 60V breakdown voltages for both collector-emitter and collector-base configurations. The device dissipates 1.0W of power with an operating junction temperature range from -55°C to +150°C. The 'K' suffix designates a DC current gain (hFE) rank of 200 to 400 at 600mA. It features a typical transition frequency of 120MHz and low saturation voltages.

Single Bipolar Transistors Feature Summary

• High DC current gain ranking of 200 to 400 for the K variant
• Capable of handling 3.0A continuous collector current
• Low collector-emitter saturation voltage for efficient switching
• RoHS compliant lead-free finish

Single Bipolar Transistors Applications

• General-purpose switching circuits
• Power amplification stages
• Driver applications requiring high current gain

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix '-TP' indicates tape-and-reel packaging containing 2,500 pieces per reel. Confirm the 'K' suffix matches the required hFE bin of 200 to 400. Ensure the component meets RoHS compliance standards if required by your manufacturing process. Check for availability of halogen-free options by adding the '-HF' suffix if necessary.

Single Bipolar Transistors Selection Notes

Select this component when a high-current NPN transistor with elevated current gain is required. The K suffix ensures a tighter gain band compared to standard variants. Consider the DPAK package for adequate thermal dissipation during operation. Verify that the 60V breakdown voltage aligns with the circuit's maximum operating conditions.

Single Bipolar Transistors Part Context

This part belongs to the 2SD1899 series of NPN silicon epitaxial transistors manufactured by Micro Commercial Components. The series includes variants with different hFE rankings, such as M and L, alongside the K variant specified here. These transistors are designed for general-purpose applications requiring reliable performance across a wide temperature range.

Single Bipolar Transistors Replacement Considerations

Direct substitutes within the same family include the 2SD1899-M and 2SD1899-L, though their hFE ranges differ. Cross-manufacturer replacements must match the DPAK footprint, 3.0A current rating, and 60V breakdown specifications.
