2N6427G

Overview

The onsemi 2N6427G is a single NPN Darlington transistor housed in a TO-92 (TO-226) through-hole package. It features a maximum collector-emitter voltage of 40 V and supports a continuous collector current of 500 mA. The device has a power dissipation rating of 350 mW and operates within a temperature range of -55°C to +100°C.

Feature Summary

Darlington configuration providing high DC current gain for sensitive switching applications
Robust NPN bipolar junction transistor structure suitable for general-purpose amplification
Through-hole mounting capability with standard leaded packaging

Applications

General-purpose switching circuits
Low-power amplifier stages
Driver circuits for relays or LEDs

Procurement Notes

Verify the specific suffix 'G' against official datasheets to confirm compliance status and environmental certifications. Confirm package dimensions match the target PCB footprint. Check for obsolescence notices as this component may be discontinued or subject to change.

Selection Notes

Select this part when a high-gain NPN switch is required in a compact through-hole form factor. Ensure the load current does not exceed 500 mA and that thermal management accommodates the 350 mW dissipation limit at the expected ambient temperature.

Part Context

This component belongs to the 2N642x series of Darlington transistors from onsemi. It serves as a legacy alternative to modern surface-mount devices, offering comparable electrical characteristics in a traditional axial-leaded package for through-hole assembly processes.
