2SAR553PFRAT100

Single Bipolar Transistors Overview

The ROHM Semiconductor 2SAR553PFRAT100 is a PNP bipolar junction transistor (BJT) designed for automotive applications, certified to AEC-Q101 standards. It features a collector-emitter voltage (Vceo) of -50 V and a continuous collector current (Ic) of -2.0 A. The device operates in an MPT3 package (TO-243AA/SOT-89), offering a power dissipation (Pd) of 0.5 W. Key electrical characteristics include a DC current gain (hFE) range of 180 to 450 at -50 mA/-2 V, a collector-emitter saturation voltage (Vce(sat)) of 400 mV, and a transition frequency (fT) of 320 MHz. It supports a maximum operating temperature of +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official ROHM documentation to confirm package type and tape quantity. Confirm AEC-Q101 compliance status directly from the datasheet. Check for 'Not Recommended for New Designs' status if applicable to your design timeline. Ensure the MPT3 footprint matches your PCB layout requirements before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when a PNP BJT with -50 V and -2 A ratings is required for automotive environments. Consider the MPT3 package size constraints and 0.5 W power dissipation limit. Compare hFE ranges and Vce(sat) values against circuit requirements. Verify compatibility with existing supply chains if replacing legacy parts like the 2SAR553PFRA.

Single Bipolar Transistors Part Context

This part belongs to the 2SAR series of PNP transistors manufactured by ROHM Semiconductor. It is specifically engineered for automotive electronics, meeting rigorous quality and reliability standards. The MPT3 package provides a compact solution for surface-mount assembly, balancing current capacity with thermal performance in space-constrained designs.

Single Bipolar Transistors Replacement Considerations

The 2SAR553PHZGT100 is a recommended replacement with identical pinout, package, and specifications. Both parts share the same MPT3 form factor and electrical ratings. Verify that the substitute maintains the required AEC-Q101 certification for your specific application environment.
