G1010 MOSFET — Specifications & Equivalents

About the G1010

The G1010 is a MOSFET with a drain–source voltage (V_DS) rating of 60 V and a continuous drain current (I_D) of 100 A. It can dissipate up to 200 W and is rated to a junction temperature of 175 °C. It is supplied in the TO220 package.

At a glance

• Type: MOSFET

• Max junction temperature (T_J): 175 °C
• Package: TO220

Typical applications

With its 60 V drain–source rating the G1010 sits in the mid-range class of switching MOSFETs, typically found in 24 V and 48 V industrial and battery systems, motor drives and H-bridges and load and hot-swap switching.

The 100 A current rating puts it in high-current territory, where conduction loss (I² × R_DS(on)) and thermal design usually matter more than switching loss. Budget for adequate copper area and a heatsink.

Gate drive and switching notes

Keep gate–source voltage within the ±20 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.

Switching behaviour is characterised by an output capacitance (C_oss) of 671.5 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the G1010

A drop-in substitute for the G1010 should match its polarity and offer a drain–source rating of at least 60 V and a continuous drain current rating of at least 100 A.

Mechanically, check the replacement against the TO220 footprint and confirm the pin order — parts sharing a package outline do not always share a pinout.

Where the application switches inductive loads or runs near the voltage limit, keep extra headroom rather than choosing a part that only just meets the original numbers.

Frequently asked questions

What is the G1010?

The G1010 is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 60 V drain-source and 100 A continuous drain current.

What is the maximum voltage of the G1010?

The G1010 has a maximum drain-source voltage (Vds) of 60 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the G1010 handle?

It is rated for 100 A of continuous drain current, with power dissipation limited to 200 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the G1010 come in?

It is listed in TO220. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the G1010?

This page lists 17 candidate equivalents matched on electrical ratings and package. Any replacement should meet or exceed the original voltage, current and dissipation figures and use a compatible drive level.
