2SC4108M is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists onsemi. Its product description is TRANS NPN 400V 12A TO-3PB. Review the specifications below when checking this part for your BOM.
The onsemi 2SC4108M is a power NPN bipolar junction transistor designed for high-voltage switching applications. It features a collector current rating of 12A and a collector-emitter breakdown voltage of 400V. The device utilizes a TO-3PB flange mount package, facilitating efficient heat dissipation with a maximum power dissipation capacity of 100W. Constructed from silicon, it operates at temperatures up to 150°C and maintains a minimum DC current gain of 15.
Verify the specific manufacturer source, as original documentation references Sanyo. Confirm that the 'M' suffix corresponds to the standard TO-3PB flange mount package without altering electrical ratings. Ensure compatibility with existing thermal management solutions due to the 100W power dissipation requirement.
Select this component for designs requiring high voltage isolation and significant current handling. The TO-3PB package necessitates appropriate mounting hardware for thermal conduction. Verify that the circuit design accommodates the 400V breakdown limit and that drive signals support the required switching speeds.
This transistor belongs to the family of triple diffused planar silicon transistors utilizing MBIT process technology. It is engineered for high reliability and is often paired with complementary PNP devices in push-pull configurations for audio and power conversion systems.
