2SD2195T100

Single Bipolar Transistors Overview

The 2SD2195T100 is an NPN Darlington transistor manufactured by Rohm Semiconductor, designed for surface-mount applications in the MPT3 (TO-243AA) package. It features a maximum collector-emitter voltage of 100 V and a continuous collector current rating of 2 A. The device offers a high DC current gain of at least 1000 at 1 A and 2 V, with a transition frequency of 80 MHz. Maximum power dissipation is rated at 2 W, and it supports a junction temperature up to 150°C. The saturation voltage is specified at a maximum of 1.5 V under standard test conditions.

Single Bipolar Transistors Procurement Notes

Verify component authenticity through authorized distribution channels due to the NRND status. Confirm that the MPT3 package dimensions align with existing PCB footprints. Ensure thermal management strategies account for the 2 W dissipation limit. Validate RoHS compliance documentation if required for specific regulatory environments. Check for obsolescence notices from the manufacturer before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when high gain and moderate voltage ratings are required in a compact surface-mount form factor. Consider the 100 V breakdown voltage for applications exceeding standard low-voltage logic levels. Evaluate the 2 A current capacity against peak load requirements. Compare the MPT3 package thermal characteristics with alternative packages if heat dissipation is critical. Verify compatibility with existing drive circuitry given the Darlington configuration.

Single Bipolar Transistors Part Context

This part belongs to Rohm's discrete semiconductor lineup, specifically within the bipolar junction transistor category. The 2SD2195 series utilizes Darlington architecture to achieve superior current gain compared to single-transistor designs. The T100 suffix indicates the specific tape-and-reel packaging format intended for high-volume manufacturing integration.

Single Bipolar Transistors Replacement Considerations

Publicly confirmed substitute part numbers include 2SCR552P5 and 2SCR552PHZG, which share the same pinout and MPT3 package configuration.
