2SD2098T100S is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Rohm Semiconductor. Its product description is TRANS NPN 20V 5A MPT3. Review the specifications below when checking this part for your BOM.
The 2SD2098T100S is an NPN silicon epitaxial planar transistor designed for strobe flash applications. It features a low collector-emitter saturation voltage of 0.25V typical at IC/IB = 4A/0.1A and excellent DC current gain characteristics. The device supports a maximum collector current of 5A DC and 10A pulse, with a collector-emitter breakdown voltage of 20V and collector-base breakdown voltage of 50V. Power dissipation reaches 10W on a ceramic board or 1W on a standard PCB. Transition frequency is 150MHz.
Verify the specific suffix T100S against the official ROHM datasheet to confirm packaging type and hFE binning classification. Ensure design compliance with absolute maximum ratings, particularly regarding thermal management for power dissipation limits on different substrate types.
Select this component when low saturation voltage is critical for efficiency in high-current strobe applications. Compare against complementary PNP models like the 2SB1386 for matched pairs. Verify that the required hFE range aligns with the available R or Q classifications specified in the ordering information.
This part belongs to the 2SD2098 series, which includes variants like the 2SD2118 and 2SD2097. These transistors are engineered specifically for strobe flash drivers, offering superior saturation characteristics compared to standard general-purpose NPN transistors.
The datasheet lists the 2SB1386, 2SB1412, and 2SB1326 as complementary parts. No direct NPN replacements are explicitly confirmed in the provided text.
