2SD1664T100R is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Rohm Semiconductor. Its product description is TRANS NPN 32V 1A MPT3. Review the specifications below when checking this part for your BOM.
The 2SD1664T100R is an NPN silicon medium power transistor manufactured by Rohm Semiconductor. It features a low collector-emitter saturation voltage of 0.15V typical at IC/IB = 500mA/50mA. The device is designed to complement the 2SB1132 and 2SB1237 PNP transistors. It utilizes an epitaxial planar structure for reliable performance in general-purpose switching and amplification applications.
Verify the specific hFE binning classification required for the application, as electrical characteristics are classified into groups. Confirm that the T100R suffix corresponds to the correct tape-and-reel packaging quantity specified in the official datasheet before finalizing procurement orders.
Select this component when a low saturation voltage is critical for efficiency in NPN switching applications. Ensure the design accounts for its complementary pairing with the 2SB1132 or 2SB1237 if a matched pair configuration is necessary for the circuit topology.
This part belongs to Rohm's medium power transistor series, specifically engineered for general-purpose use. It serves as the NPN counterpart to the 2SB1132 and 2SB1237, providing a balanced solution for push-pull or complementary amplifier designs where low voltage drop is beneficial.
The 2SD1858 is listed alongside the 2SD1664 in the same datasheet, suggesting functional similarity. Verify pinout and electrical specifications against the 2SD1858 datasheet to confirm interchangeability for specific circuit requirements.
