2SAR543RTL

Single Bipolar Transistors Overview

The 2SAR543RTL is a single PNP bipolar junction transistor manufactured by Rohm Semiconductor. It features a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 3 A. The device operates with a transition frequency of 300 MHz and supports a maximum power dissipation of 1 W. It utilizes the TSMT3 surface-mount package, also identified as SC-96. Key electrical characteristics include a DC current gain (hFE) minimum of 180 at 100 mA and 3 V, and a collector-emitter saturation voltage of 400 mV at 100 mA base current and 2 A collector current. The component supports a maximum junction temperature of 150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, such as tape-and-reel or cut-tape formats, as these affect handling procedures. Confirm RoHS3 compliance status for environmental regulations. Check the manufacturer's latest datasheet for any updates on moisture sensitivity levels or recommended soldering profiles to prevent component damage during assembly processes.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 50 V breakdown and 3 A current capacity is required in a compact surface-mount form factor. Ensure the application circuit can accommodate the specified saturation voltage and power dissipation limits. Consider the TSMT3 package dimensions for PCB layout constraints and verify that the operating temperature range aligns with the system's thermal environment.

Single Bipolar Transistors Part Context

This part belongs to the 2SAR series of PNP transistors from Rohm Semiconductor, designed for general-purpose use. It shares the core electrical specifications with other variants in the family but differs in packaging and reel configurations. The TSMT3 package provides a small footprint suitable for dense board layouts while maintaining adequate thermal performance for moderate power applications.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the 2SCR543RTL for NPN polarity requirements with identical electrical ratings. Other compatible options may include parts from the same manufacturer offering similar voltage and current specifications in equivalent surface-mount packages.
