2N6426 Description

Short technical summary and product information.

The 2N6426 is an NPN Darlington transistor manufactured by On Semiconductor. It is designed for applications requiring extremely high current gain at currents up to 1.0 A. The device offers a collector-emitter breakdown voltage of 40 V and a continuous collector current rating of 1.2 A. With a DC current gain (hFE) ranging from 20,000 to 300,000 depending on test conditions, this transistor provides exceptional amplification capability.

 

Key electrical characteristics include a maximum collector-emitter saturation voltage of 1.5 V at 500 mA collector current and 500 µA base current, and a maximum base-emitter saturation voltage of 2.0 V. The device has an output capacitance of 7.0 pF and a maximum noise figure of 10 dB, making it suitable for low-level signal amplification.

 

The 2N6426 is housed in a TO-226-3 / TO-92-3 Long Body through-hole package, with a supplier device package designation of TO-92 (TO-226). It operates over a junction temperature range of -55°C to 150°C and has a maximum power dissipation of 625 mW. The thermal resistance from junction to ambient is 200°C/W.
