2SCR542PT100

Single Bipolar Transistors Overview

The 2SCR542PT100 is an NPN silicon middle power transistor manufactured by ROHM Semiconductor. It features a collector-emitter voltage (VCEO) of 30V and a continuous collector current (IC) of 3.0A. The device is housed in the MPT3 surface-mount package, equivalent to TO-243AA or SOT-89. Key electrical parameters include a DC current gain (hFE) ranging from 200 to 500 at IC=500mA and VCE=2V, and a transition frequency (fT) of 280MHz. Maximum power dissipation is rated at 2W, with a maximum operating junction temperature of +150°C.

Single Bipolar Transistors Feature Summary

• High current handling capability suitable for medium-power switching applications
• Optimized for high-frequency operation with a 280MHz transition frequency
• Designed for surface-mount assembly using the compact MPT3 package

Single Bipolar Transistors Applications

• General-purpose switching circuits
• Driver stages for power loads
• Amplifier output stages

Single Bipolar Transistors Procurement Notes

Verify the specific suffix PT100 against official ROHM documentation to confirm tape-and-reel packaging and quantity. Confirm RoHS compliance status and automotive qualification if required for your design. Check for obsolescence notices as this component may be subject to production lifecycle changes.

Single Bipolar Transistors Selection Notes

Select this component when a 30V NPN transistor with 3A current capacity is required in a small surface-mount footprint. Ensure the thermal management design supports the 2W power dissipation rating. Compare hFE ranges and fT specifications against circuit requirements to ensure adequate gain and speed performance.

Single Bipolar Transistors Part Context

This part belongs to the 2SCR series of NPN middle power transistors from ROHM. These devices are designed for general-purpose use in consumer electronics and industrial equipment. The MPT3 package provides a balance between power handling and board space efficiency compared to larger through-hole packages.

Single Bipolar Transistors Replacement Considerations

Direct pin-compatible substitutes within the same family include 2SCR542P. Verify that alternative parts match the 30V/3A ratings and MPT3 package dimensions before integration.
