2SB1590KT146Q

Single Bipolar Transistors Overview

The 2SB1590KT146Q is a PNP bipolar junction transistor manufactured by Rohm Semiconductor, designed for low-frequency amplifier applications. It features a collector-emitter voltage of -15V and a continuous collector current rating of -1A within an SMT3 (SOT-346) surface-mount package. The device achieves a maximum DC current gain (hFE1) of 270 at -50mA and maintains a transition frequency of 200MHz. Key electrical characteristics include a collector-base breakdown voltage of -15V and a saturation voltage of -300mV under specified drive conditions.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'Q' against the official datasheet to confirm binning or grading requirements. Confirm that the SMT3 package dimensions align with your PCB footprint constraints. Ensure ambient temperature derating calculations are performed to stay within the 200mW power dissipation limit. Validate RoHS compliance status for your target market regulations before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with -1A current capacity and -15V voltage rating is required for low-frequency amplification. Consider its complementary relationship with the 2SD2444K if balanced push-pull configurations are needed. Evaluate the SOT-346 package size against available board space. Verify that the 200MHz transition frequency meets the signal bandwidth requirements of the intended application circuit.
