2N6043 Description

Short technical summary and product information.

The 2N6043 is an NPN Darlington transistor from On Semiconductor designed for general-purpose amplifier and low-speed switching applications. It features a monolithic construction with built-in base-emitter shunt resistors, providing high DC current gain of 1000 minimum at 4A collector current and 4V collector-emitter voltage.

 

Key electrical ratings include a maximum collector-emitter voltage of 60V, continuous collector current of 8A (16A peak), and maximum power dissipation of 75W at 25°C case temperature. The device offers a low collector-emitter saturation voltage of 2V maximum at 16mA base current and 4A collector current, making it suitable for efficient switching.

 

The transistor is housed in a TO-220-3 through-hole package with a junction-to-case thermal resistance of 1.67°C/W. It operates over a junction temperature range of -65°C to 150°C and features ESD ratings exceeding 8000V (Human Body Model) and 400V (Machine Model). The device is Pb-Free and RoHS compliant.
