The onsemi 2N7000G is a small signal N-channel enhancement mode MOSFET designed for general-purpose switching applications. It features a maximum drain-source voltage of 60 V and a continuous drain current of 200 mA. The device utilizes planar DMOS technology to achieve low power drive requirements and high input impedance. Packaged in a TO-92 through-hole configuration, it offers a typical gate charge of 0.8 nC and a maximum on-resistance of 5 Ω. The component operates within a temperature range of -55°C to +150°C with a power dissipation rating of 400 mW.
Verify the specific datasheet revision and ordering suffix when sourcing. Confirm that the TO-92 package variant matches the required pinout and mechanical dimensions for the target PCB layout. Ensure compliance with RoHS directives if applicable to the manufacturing region. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Select this component for low-current switching tasks where through-hole mounting is preferred over surface mount alternatives. Consider the 5 Ω on-resistance when calculating conduction losses at higher currents. Evaluate the 200 mA continuous current limit against peak load requirements. Verify that the 60 V breakdown voltage exceeds the maximum circuit voltage with adequate safety margin.
This device belongs to the widely used 2N7000 series of small signal MOSFETs. It serves as a standard replacement for legacy silicon-based N-channel transistors in educational and industrial designs. The TO-92 package allows for easy prototyping and manual assembly. It is commonly found in consumer electronics and control boards requiring simple low-power switching functions.
Direct substitutes include the 2N7000 from other manufacturers such as Vishay or Microchip. Verify pinout compatibility and electrical parameter equivalence before substitution. Surface-mount equivalents like the 2N7002 require PCB redesign due to different packaging.
