2SC2412KT146R is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Rohm Semiconductor. Its product description is TRANS NPN 50V 0.15A SMT3. Review the specifications below when checking this part for your BOM.
The 2SC2412KT146R is a general-purpose NPN bipolar junction transistor manufactured by Rohm Semiconductor. It features a collector-emitter voltage of 50 V and a maximum collector current of 150 mA, with a power dissipation rating of 200 mW. The device exhibits a transition frequency of 180 MHz and low output capacitance of 2.0 pF typical. It operates within a junction temperature range of -55 °C to +150 °C and utilizes the SMT3 (SOT-346) surface-mount package.
Verify the component against the official Rohm datasheet revision 007 dated September 20, 2024. Confirm that the marking code corresponds to 'QR B' and the packaging matches the specified taping code T146. Ensure the product meets RoHS3 compliance standards before integration into designs.
Select this component when a 50V NPN transistor with 150mA capability is required in an SMT3 package. Consider its 180MHz transition frequency for suitable bandwidth requirements. Verify compatibility with existing complementary PNP devices if used in push-pull configurations.
This part belongs to the 2SC2412K series, which includes variants like 2SC4617E3 and 2SC4081U3 sharing similar electrical characteristics but differing in physical packages.
