2SAR573D3TL1

Single Bipolar Transistors Overview

The 2SAR573D3TL1 is a PNP power transistor manufactured by ROHM Semiconductor, housed in a TO-252 (DPAK) surface-mount package. It features a collector-emitter voltage of -50V and a continuous collector current of -3A. The device offers a maximum power dissipation of 10W and a low collector-emitter saturation voltage of -400mV at an Ic/Ib ratio of -1A/-50mA. DC current gain ranges from 180 to 450. It is designed for low-frequency amplification and power driver applications.

Single Bipolar Transistors Feature Summary

• Low collector-emitter saturation voltage for efficient power switching
• High DC current gain suitable for driving loads
• Designed for low-frequency amplification purposes

Single Bipolar Transistors Applications

• Power driver circuits
• Low-frequency amplifier stages

Single Bipolar Transistors Procurement Notes

Verify the specific suffix TL1 corresponds to the tape-and-reel packaging configuration with a standard quantity of 2500 units per reel. Confirm RoHS compliance status and ensure the component meets the required automotive or industrial grade specifications if applicable, as standard grades may have different reliability ratings than AEC-Q101 qualified parts.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with -50V breakdown and -3A current capacity is required in a TO-252 package. Ensure the application operates within the specified storage temperature range of -55°C to 150°C. Verify that the drive current requirements align with the hFE characteristics to maintain the desired saturation voltage performance.

Single Bipolar Transistors Part Context

This part belongs to ROHM's series of low VCE(sat) power transistors. It serves as the complementary PNP counterpart to NPN types such as the 2SCR573D3. The device is classified as a standard-grade product and is explicitly noted as not recommended for use in automotive equipment unless specified otherwise by a different grade variant.

Single Bipolar Transistors Replacement Considerations

The 2SCR573D3 is documented as the complementary NPN type. For direct PNP replacement, verify pinout compatibility and electrical parameters against the original design requirements. No other specific substitute part numbers are confirmed in the provided documentation.
