2SD2153T100U

Single Bipolar Transistors Overview

The ROHM Semiconductor 2SD2153T100U is a high-gain NPN bipolar junction transistor designed for low-frequency power amplifier applications. It features a SOT-89 (MPT3) surface-mount package with SC-62 JEITA designation. Key electrical parameters include a collector-emitter voltage of 25V, a continuous collector current of 2A, and a maximum power dissipation of 0.5W on a reference land or 2.0W on a ceramic board. The device offers a DC current gain ranging from 560 to 2700 depending on the rank, a transition frequency of 110MHz, and a typical saturation voltage of 120mV at specified drive conditions.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank (U, V, or W) required for your design, as the datasheet classifies gain into distinct ranges. Confirm that the SOT-89 footprint matches your PCB layout constraints. Ensure thermal management strategies account for the 0.5W dissipation limit under standard mounting conditions versus the higher rating on ceramic substrates. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is needed for low-frequency power amplification. The 25V collector-emitter voltage and 2A current capacity define its operational limits. Consider the specific hFE bin required for your circuit's biasing needs. The SOT-89 package is appropriate for surface-mount assembly where space efficiency is prioritized over high-power thermal handling capabilities found in larger packages.

Single Bipolar Transistors Part Context

This part belongs to ROHM's discrete bipolar transistor lineup, specifically optimized for amplifier duties. The 'T100' suffix indicates tape-and-reel packaging with a basic ordering unit of 1000 pieces. The marking code 'DN' identifies the device on the package body. It is distinct from Darlington configurations, offering faster transition frequencies while maintaining high current gain for linear amplification tasks.

Single Bipolar Transistors Replacement Considerations

Consult official ROHM resources for direct pinout-compatible substitutes. Verify that any alternative component matches the 25V VCEO, 2A IC, and SOT-89 package dimensions. Ensure the replacement meets the required hFE gain range and thermal dissipation characteristics for your specific application environment.
