2SC4617

Single Bipolar Transistors Overview

The onsemi 2SC4617 is an NPN silicon general-purpose amplifier transistor designed for surface-mount applications. It features a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device offers a transition frequency of 180 MHz and a DC current gain (hFE) ranging from 120 to 560. Power dissipation is rated at 125 mW, with a collector-emitter saturation voltage of 400 mV. It is housed in the SC-75 (SOT-416) package and supports operating temperatures up to +150°C.

Single Bipolar Transistors Feature Summary

• Designed for low-power surface-mount applications to minimize board space requirements.

• Consumer electronics signal processing

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer designation, as onsemi acquired ROHM's discrete semiconductor business. Confirm that the ordering suffix matches the required electrical tolerances and packaging format. Ensure the component meets RoHS compliance standards for your region. Check datasheet revisions for any updates to absolute maximum ratings or thermal characteristics before finalizing procurement specifications.

Single Bipolar Transistors Selection Notes

Select this component when a compact NPN transistor with moderate voltage handling and high gain is required. Compare the 100 mA current limit against load requirements. Consider the complementary PNP transistor 2SA1774 if matched pairs are needed. Verify that the SC-75 footprint aligns with the PCB layout constraints and soldering capabilities.

Single Bipolar Transistors Part Context

This part belongs to the 2SC4617 series of NPN silicon transistors originally developed by ROHM and now distributed by onsemi. The series includes various automotive-grade variants such as the 2SC4617FRA and 2SC4617E3HZG, which meet AEC-Q101 standards. The standard commercial grade 2SC4617 is intended for general consumer and industrial applications rather than harsh automotive environments.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitute part numbers include 2SC4617EBTLR and 2SC4617EB-R. These alternatives share similar NPN characteristics and SOT-416/EMT3 packaging but may originate from different manufacturers within the same product lineage.
