2SA2048KT146Q

Single Bipolar Transistors Overview

The Rohm Semiconductor 2SA2048KT146Q is a PNP silicon epitaxial planar transistor designed for medium power applications. It operates with a collector-emitter voltage of -30V and a continuous collector current of -1.0A, dissipating up to 200mW. The device features a transition frequency of 350MHz and a typical fall time of 20ns at -1.0A. DC current gain ranges from 120 to 390 depending on the QR rank. It utilizes an SMT3 package and is supplied in taping format with 3000 pieces per basic ordering unit.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank (QR) required for your circuit design, as gain varies between 120-270 and 180-390. Confirm the SMT3 package dimensions match your PCB footprint. Ensure the -30V voltage rating meets your system's maximum operating limits. Check that the 200mW power dissipation is sufficient for your thermal environment.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with high-speed switching characteristics is needed. It complements the 2SC5730K NPN transistor for complementary pairs. Consider the 350MHz transition frequency for frequency-sensitive designs. Verify the -1.0A current limit against peak load requirements.
