The 2SD1898G T100R is a silicon NPN bipolar transistor manufactured by Rohm Semiconductor. It is designed for switching and amplifier applications requiring high voltage and current handling capabilities. This transistor is known for its robust performance and reliability in demanding industrial and consumer electronics applications.

Applications:

• Switching Regulators in Power Supplies
• High-Voltage Inverters
• Motor Control Circuits
• General-Purpose Amplification

Features:

• High Collector-Emitter Voltage (VCEO)
• High Collector Current (IC)
• Low Saturation Voltage (VCE(sat))
• Fast Switching Speed
• High Power Dissipation

Benefits:

• High Voltage Operation: The high VCEO allows for use in high-voltage circuits without breakdown concerns.
• High Current Handling: The high IC rating enables driving high-current loads effectively.
• Efficient Switching: The low VCE(sat) minimizes power losses during switching, leading to higher efficiency.
• Robust and Reliable: Designed for reliable performance in harsh operating conditions.

Specifications:

The 2SD1898G T100R typically features a collector-emitter voltage (VCEO) of 400V, a collector current (IC) of 5A, and a collector power dissipation (PC) of 40W. The saturation voltage (VCE(sat)) is generally low, contributing to its efficiency. The transition frequency (fT) is also relatively high, allowing for fast switching speeds. Package: TO-220.
