Single Bipolar Transistors Procurement Notes

Verify that the specific ordering suffix matches the required packaging format, as the base part number may be available in different tape-and-reel quantities. Confirm the supply status indicates availability for new designs, as some variants are marked as not recommended for new designs. Ensure the component meets the specific AEC-Q101 qualification requirements for your target application environment.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with high current handling capability (-3 A) and automotive certification is required. The SOT-89 package offers a balance between thermal performance and board space. Compare the hFE range against load requirements to ensure adequate drive capability. Verify that the -30 V voltage rating exceeds the maximum circuit operating voltage with appropriate safety margins.

Single Bipolar Transistors Part Context

This component belongs to the 2SAR series of PNP transistors manufactured by ROHM Semiconductor. It is functionally similar to the 2SAR552PHZG variant, sharing identical pinout, package dimensions, and electrical specifications. Both parts utilize the MPT3 (SOT-89) package and are designed for middle-power applications requiring robust performance in compact form factors.

Single Bipolar Transistors Replacement Considerations

The 2SAR552PHZGT100 is a confirmed substitute with the same pinout, package, and electrical ratings. Both components share identical specifications including -30V Vceo, -3A Ic, and 200-500 hFE range. Verify that the replacement part maintains the required AEC-Q101 qualification if automotive compliance is mandatory.
