2SC4105M

Single Bipolar Transistors Overview

The onsemi 2SC4105M is a single NPN silicon power bipolar transistor housed in a TO-220AB flange mount package. It supports a maximum collector current of 4 A and a collector-emitter breakdown voltage of 400 V. The device features a transition frequency of 20 MHz and a maximum power dissipation of 1.75 W. Designed for high reliability, it utilizes the MBIT process to ensure fast switching speeds and a wide safe operating area (ASO).

Single Bipolar Transistors Feature Summary

• High breakdown voltage capability with 400V rating.
• Fast switching speed enabled by MBIT process technology.
• Wide Safe Operating Area (ASO) for robust performance.

Single Bipolar Transistors Applications

• Power switching circuits requiring high voltage isolation.
• General purpose amplifier applications.
• Industrial control systems utilizing NPN power transistors.

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer origin, as the 2SC4105M designation is historically associated with Sanyo Semicon Device. Ensure that the received component matches the onsemi branding if specified, and confirm the physical package integrity and pin configuration against the TO-220AB standard before integration into the circuit design.

Single Bipolar Transistors Selection Notes

Select this component when a single NPN power transistor with a 400V collector-emitter voltage and 4A continuous current capacity is required. The TO-220AB package facilitates through-hole mounting and heat dissipation. Consider the 20MHz transition frequency for medium-speed switching applications where wide ASO and high reliability are critical design parameters.

Single Bipolar Transistors Part Context

This part belongs to the family of power bipolar transistors designed for general-purpose use. It shares similar electrical characteristics with variants such as the 2SC4105N-RC, which also offers 400V and 4A ratings but may differ in minimum DC current gain specifications. The series emphasizes high reliability and fast switching capabilities suitable for demanding electronic environments.

Single Bipolar Transistors Replacement Considerations

The 2SC4105N-RC is a documented equivalent offering identical 400V and 4A ratings in a TO-220AB package. Verify that the replacement meets the specific hFE requirements for the application, as the N-RC variant specifies a minimum hFE of 30 compared to other potential variants.
