2SAR553P5T100

Single Bipolar Transistors Overview

The ROHM Semiconductor 2SAR553P5T100 is a PNP bipolar junction transistor (BJT) designed for middle-power driver applications. It features a collector-emitter voltage (VCEO) of -50 V and a continuous collector current (Ic) of -2 A. The device utilizes the MPT3 package, equivalent to TO-243AA or SOT-89, with three terminals. Key electrical parameters include a DC current gain (hFE) ranging from 180 to 450 at -50 mA and -2 V, and a transition frequency (fT) of 320 MHz. Power dissipation is rated at 1 W, with a maximum operating temperature of +150°C.

Single Bipolar Transistors Feature Summary

• Low saturation voltage typically -400 mV max at Ic/Ib = -700mA/-35mA

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix T100 to confirm tape-and-reel packaging containing 1000 units per reel. Confirm RoHS compliance status and JEITA package classification SC-62 against current datasheet revisions. Ensure design-in compatibility with existing thermal management solutions for the MPT3 footprint before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with -50 V rating and -2 A current capacity is required in a compact surface-mount form factor. The MPT3 package offers a balance between power handling and board space efficiency. Consider the hFE range of 180 to 450 for biasing stability requirements in driver stages.

Single Bipolar Transistors Part Context

This part belongs to the 2SARx series of PNP transistors manufactured by ROHM Semiconductor. It serves as a successor or alternative to older variants like the 2SAR553P, which is marked as not recommended for new designs. The 2SAR553P5T100 maintains pinout compatibility with similar packages while offering updated performance characteristics for modern electronic designs.

Single Bipolar Transistors Replacement Considerations

The 2SAR553P5 is listed as a similar level replacement with the same pinout and package. Verify electrical parameter alignment before substitution.
