2SC4027T-TL-H

Single Bipolar Transistors Overview

The onsemi 2SC4027T-TL-H is a single NPN bipolar junction transistor (BJT) designed for general-purpose switching and amplification applications. It utilizes silicon planar epitaxial technology to ensure high reliability and consistent performance across operating conditions. The device features a collector current rating of 1.5 A and a collector-emitter voltage breakdown of 160 V, making it suitable for medium-power circuits. Key electrical characteristics include a transition frequency of 120 MHz and a maximum power dissipation of 1 W. It is housed in a surface-mount TO-252-3 (DPAK) package, facilitating automated assembly and compact board layouts.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix TL-H against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS and REACH regulations as stated in the manufacturer's declaration. Cross-reference the full part number with authorized distributors to avoid counterfeit components. Confirm that the intended application does not exceed the absolute maximum ratings defined in the datasheet.

Single Bipolar Transistors Selection Notes

Select this component when a surface-mount NPN transistor with 160 V blocking capability and 1.5 A continuous current is required. Consider the TO-252-3 package for its balance of thermal performance and footprint size. Evaluate the 120 MHz transition frequency to ensure suitability for the target signal bandwidth. Compare power dissipation limits against the expected thermal environment of the final assembly.

Single Bipolar Transistors Part Context

This device belongs to the 2SC4027 series of NPN transistors manufactured by onsemi. The series is characterized by silicon planar epitaxial construction, which provides improved switching speeds and higher breakdown voltages compared to older technologies. The 2SC4027T-TL-H variant specifically denotes the surface-mount DPAK configuration, distinguishing it from through-hole equivalents within the same functional family.

Single Bipolar Transistors Replacement Considerations

Consult the onsemi datasheet for direct pin-compatible alternatives within the same voltage and current class. Verify that any substitute maintains the same TO-252-3 footprint and thermal resistance characteristics. Ensure the replacement device meets the same electrical specifications for hFE and fT to maintain circuit performance integrity.
