2SAR340PT100Q

Single Bipolar Transistors Overview

The 2SAR340PT100Q is a PNP silicon bipolar junction transistor from the 2SxR series, manufactured by ROHM Semiconductor. It features a collector-emitter voltage (VCEO) of -400 V and a continuous collector current (Ic) of -100 mA. The device is housed in an MPT3 (SOT-89-3) surface-mount package with a power dissipation rating of 0.5 W at 25°C. Key electrical characteristics include a DC current gain (hFE) ranging from 82 to 270 at Ic = -10 mA, and a collector-emitter saturation voltage (VCE(sat)) of -400 mV maximum at Ic/Ib = -20mA/-2mA.

Single Bipolar Transistors Feature Summary

• High voltage capability with -400 V collector-emitter breakdown voltage for robust operation in high-voltage circuits.
• Low saturation voltage design minimizes power loss during switching or amplification states.
• Complementary NPN counterpart available as the 2SCR346P for balanced push-pull configurations.

Single Bipolar Transistors Applications

• Low frequency amplifier circuits
• Switching applications requiring high voltage isolation

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'Q' against the official ROHM datasheet to confirm if it denotes a specific hFE rank or packaging variation distinct from the standard 'T100' reel configuration. Ensure compatibility with RoHS directives and check for any REACH SVHC declarations relevant to the manufacturing batch before finalizing procurement specifications.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring high voltage handling in a compact SMD form factor. Consider the thermal constraints of the MPT3 package, which limits continuous power dissipation to 0.5 W without significant heatsinking. Evaluate the hFE classification requirements, as the device offers specific gain ranges suitable for precise biasing in low-frequency amplification tasks.

Single Bipolar Transistors Part Context

This part belongs to the 2SxR series of middle power transistors from ROHM. It is designed for surface mount technology, offering a balance between high voltage performance and small footprint. The MPT3 package provides efficient thermal management relative to its size, making it suitable for dense PCB layouts in consumer and industrial electronics.

Single Bipolar Transistors Replacement Considerations
