2N7007 MOSFET — Specifications & Equivalents

About the 2N7007

The 2N7007 is an N-channel MOSFET with a drain–source voltage (V_DS) rating of 240 V, a continuous drain current (I_D) of 0.065 A and an on-resistance (R_DS(on)) of 45 Ω. It can dissipate up to 1 W and is rated to a junction temperature of 125 °C. It is supplied in the TO92 package.

Typical applications

With its 240 V drain–source rating the 2N7007 sits in the medium-high-voltage class of switching MOSFETs, typically found in telecom and industrial DC rails, boost and flyback converters, LED and backlight drivers and power-factor-correction stages. Common where the bus sits well above 100 V but below rectified mains.

At 0.065 A it is aimed at small-signal and light-load switching rather than power conversion.

On-resistance of 45 Ω is relatively high, so this part is better suited to low duty-cycle or low-current switching than to continuous high-current conduction.

Gate drive and switching notes

Keep gate–source voltage within the ±30 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.

Switching behaviour is characterised by an output capacitance (C_oss) of 15 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the 2N7007

A drop-in substitute for the 2N7007 must be the same N-channel type and offer a drain–source rating of at least 240 V, a continuous drain current rating of at least 0.065 A and an on-resistance no higher than 45 Ω if efficiency and heat matter.

Mechanically, check the replacement against the TO92 footprint and confirm the pin order — parts sharing a package outline do not always share a pinout.

Because 2N7007 is a JEDEC-registered part number rather than one vendor's proprietary series, it is produced by several manufacturers. Datasheet figures vary slightly between them, so check the datasheet of the brand you actually buy — this also makes like-for-like sourcing easier.

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 2N7007?

The 2N7007 is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 240 V drain-source and 0.065 A continuous drain current.

What is the maximum voltage of the 2N7007?

The 2N7007 has a maximum drain-source voltage (Vds) of 240 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the 2N7007 handle?

It is rated for 0.065 A of continuous drain current, with power dissipation limited to 1 W. Real-world capability depends on your heatsinking and ambient temperature.

What is the on-resistance of the 2N7007?

On-resistance (Rds(on)) is 45 Ω. Multiply by the square of your load current to estimate conduction loss.

What package does the 2N7007 come in?

It is listed in TO92. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the 2N7007?

No verified equivalents are listed yet. Choose a part of the same polarity that meets or exceeds every rating above and shares a compatible package and pinout.
