P1510ATG MOSFET — Specifications & Equivalents

About the P1510ATG

The P1510ATG is an N-channel MOSFET with a drain–source voltage (V_DS) rating of 100 V, a continuous drain current (I_D) of 64 A and an on-resistance (R_DS(on)) of 0.015 Ω. It can dissipate up to 150 W and is rated to a junction temperature of 175 °C. It is supplied in the TO220 package.

Typical applications

With its 100 V drain–source rating the P1510ATG sits in the medium-voltage class of switching MOSFETs, typically found in 48 V and 96 V distribution systems, solar and telecom power stages, DC motor drives and intermediate-bus DC-DC converters.

The 64 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.

The low 0.015 Ω on-resistance keeps conduction loss down, which suits synchronous rectification and continuous high-current paths.

Gate drive and switching notes

With a gate threshold (V_GS(th)) of 4 V this is not a logic-level device: driving the gate directly from a 3.3 V or 5 V microcontroller pin will leave it only partly on and cause it to overheat. Use a gate driver or level shifter, typically taking V_GS to 10 V.

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

Total gate charge (Q_g) of 131 nC sets the drive current required: average gate current is roughly Q_g × switching frequency, so faster switching needs a stronger driver.

Switching behaviour is characterised by a rise time of 110 ns and an output capacitance (C_oss) of 420 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the P1510ATG

A drop-in substitute for the P1510ATG must be the same N-channel type and offer a drain–source rating of at least 100 V, a continuous drain current rating of at least 64 A, an on-resistance no higher than 0.015 Ω if efficiency and heat matter and a comparable gate threshold, so your existing gate drive still fully enhances the device.

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 P1510ATG?

The P1510ATG is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 100 V drain-source and 64 A continuous drain current.

What is the maximum voltage of the P1510ATG?

The P1510ATG has a maximum drain-source voltage (Vds) of 100 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the P1510ATG handle?

It is rated for 64 A of continuous drain current, with power dissipation limited to 150 W. Real-world capability depends on your heatsinking and ambient temperature.

What is the on-resistance of the P1510ATG?

On-resistance (Rds(on)) is 0.015 Ω. Multiply by the square of your load current to estimate conduction loss.

Is the P1510ATG logic-level compatible?

No. The gate threshold is 4 V, so a 3.3 V or 5 V logic output cannot fully turn it on. Use a gate driver and take Vgs to around 10 V.

What package does the P1510ATG 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 P1510ATG?

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.
