2SC4115STPR

Single Bipolar Transistors Overview

The 2SC4115STPR is an NPN silicon epitaxial planar transistor designed for low-frequency applications. It features a collector-emitter breakdown voltage of 20V and a continuous collector current rating of 2A, with a peak pulse current capability of 5A. The device offers a typical collector-emitter saturation voltage of 0.2V at high drive conditions and a transition frequency of 290MHz. DC current gain ranges from 120 to 560 depending on the specific bin classification. It operates within a junction temperature range up to 150°C and is housed in the SPT (EIAJ SC-72) through-hole package.

Single Bipolar Transistors Feature Summary

• Low collector-emitter saturation voltage for efficient switching performance
• High DC current gain characteristics across varying collector currents
• Complements the complementary 2SA1585S PNP transistor

Single Bipolar Transistors Applications

• General-purpose amplification circuits
• Switching applications in audio visual equipment
• Office automation equipment drivers
• Communication device signal processing

Single Bipolar Transistors Procurement Notes

Verify the specific hFE bin code required for your design, as the STPR suffix indicates a tape-and-reel packaging format but does not define the gain range. The datasheet lists R, Q, and S bins with distinct gain limits. Confirm availability status directly with ROHM or authorized distributors, as supply levels fluctuate. Ensure the ordering part number matches the exact packaging quantity and gain specification needed for production.

Single Bipolar Transistors Selection Notes

Select this component when a low VCE(sat) NPN transistor is required for general-purpose switching or amplification. It serves as the complementary match to the 2SA1585S. Consider the SPT package for through-hole mounting requirements. Evaluate the hFE bin (R, Q, or S) based on base drive requirements. Ensure the application remains within the specified 20V collector-emitter voltage and 2A continuous current limits.

Single Bipolar Transistors Part Context

This component belongs to ROHM's low-frequency transistor lineup, specifically engineered for general-use electronic devices. It is part of a complementary pair system, designed to work alongside the 2SA1585S PNP transistor. The product is intended for standard consumer electronics rather than automotive or high-reliability safety-critical systems, aligning with ROHM's general-purpose semiconductor portfolio.

Single Bipolar Transistors Replacement Considerations

The 2SC4115S is the primary equivalent part number. Verify pinout compatibility and electrical parameters against the original design specifications before substitution. No direct cross-manufacturer equivalents are confirmed in the provided documentation.
