2SA2018E3TL

Single Bipolar Transistors Overview

The 2SA2018E3TL is a PNP bipolar junction transistor manufactured by ROHM Semiconductor, housed in an SOT-416 (EMT3) surface-mount package. It features a collector-emitter voltage of -12 V and a continuous collector current of -500 mA. The device achieves a low collector-emitter saturation voltage of -250 mV at a collector current of -200 mA and base current of -10 mA. Electrical characteristics include a DC current gain ranging from 270 to 680 at -10 mA, and a transition frequency of 260 MHz.

Single Bipolar Transistors Feature Summary

• High current capability with a maximum collector current of -500 mA
• Low collector-emitter saturation voltage for efficient switching performance
• Compact SOT-416 surface-mount package suitable for space-constrained designs

Single Bipolar Transistors Applications

• Low frequency amplifier circuits
• Driver applications requiring high current handling

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix matches the required packaging format before procurement. Confirm that the application environment remains within standard operating limits, as this component is not designated for automotive use. Ensure proper electrostatic discharge precautions are implemented during storage and mounting processes to maintain product reliability.

Single Bipolar Transistors Selection Notes

Select this component for general-purpose amplification and driver tasks where low saturation voltage is critical. It serves as a complementary counterpart to NPN transistors such as the 2SC4617E3. Evaluate thermal derating requirements carefully, as power dissipation is limited to 150 mW in the specified package configuration under standard conditions.

Single Bipolar Transistors Part Context

This part belongs to a family of low-frequency transistors including the 2SA2030 and 2SA2119K. While sharing similar electrical ratings, these variants differ in physical package dimensions and pinout configurations. The 2SA2018E3 specifically utilizes the EMT3 footprint, distinguishing it from the VMT3 and SMT3 packages used by its siblings.

Single Bipolar Transistors Replacement Considerations

Direct substitutes within the same series include the 2SA2030 and 2SA2119K. Note that these alternatives utilize different package codes (SOT-723 and SOT-346 respectively), requiring mechanical layout adjustments during replacement.
