2SAR553RHZGTL

Single Bipolar Transistors Overview

The ROHM Semiconductor 2SAR553RHZGTL is a PNP silicon bipolar junction transistor designed for automotive applications. It features a collector-emitter voltage of -50 V and a continuous collector current of -2 A. The device operates with a power dissipation of 1 W and supports a maximum junction temperature of +150 °C. Key electrical parameters include a DC current gain (hFE) ranging from 180 to 450 at -50 mA, and a transition frequency (fT) of 320 MHz. It is housed in an SOT-346T package.

Single Bipolar Transistors Feature Summary

• AEC-Q101 qualified for automotive grade reliability
• Low collector-emitter saturation voltage for efficient switching
• High DC current gain suitable for driver applications

Single Bipolar Transistors Applications

• Automotive middle power drivers
• Low frequency amplifiers
• High speed switching circuits

Single Bipolar Transistors Procurement Notes

Verify the specific suffix GTL indicates tape and reel packaging when sourcing. Confirm AEC-Q101 compliance requirements match the target automotive system specifications. Check RoHS status against environmental regulations. Ensure the SOT-346T footprint matches the PCB design constraints. Validate the 1 W power dissipation rating under actual thermal conditions.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring high reliability in automotive environments. The low saturation voltage reduces power loss during conduction. The wide hFE range allows for flexible base drive circuit design. Consider the 150 °C max operating temperature for high-heat scenarios. Compare fT performance against other PNP options if high-speed response is critical.

Single Bipolar Transistors Part Context

This part belongs to the 2SARx series of middle power transistors. It serves as the PNP complement to the NPN 2SCR553RHZGTL. The series is optimized for automotive use with robust qualification standards. It replaces older non-automotive grades like the 2SA2094 in new designs.

Single Bipolar Transistors Replacement Considerations

The 2SA2094 is listed as a similar level replacement with the same pinout and package, though it lacks AEC-Q101 qualification and has lower hFE.
