P1520ED MOSFET — Specifications & Equivalents
About the P1520ED
The P1520ED is an N-channel MOSFET with a drain–source voltage (VDS) rating of 200 V, a continuous drain current (ID) of 15 A and an on-resistance (RDS(on)) of 0.198 Ω. It can dissipate up to 83 W and is rated to a junction temperature of 150 °C. It is supplied in the TO252 package.

Typical applications
With its 200 V drain–source rating the P1520ED 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.
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 a rise time of 133 ns and an output capacitance (Coss) of 149 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.
Choosing a replacement for the P1520ED
A drop-in substitute for the P1520ED must be the same N-channel type and offer a drain–source rating of at least 200 V, a continuous drain current rating of at least 15 A and an on-resistance no higher than 0.198 Ω if efficiency and heat matter.
Mechanically, check the replacement against the TO252 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 P1520ED?
The P1520ED is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 200 V drain-source and 15 A continuous drain current.
What is the maximum voltage of the P1520ED?
The P1520ED has a maximum drain-source voltage (Vds) of 200 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.
How much current can the P1520ED handle?
It is rated for 15 A of continuous drain current, with power dissipation limited to 83 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the P1520ED?
On-resistance (Rds(on)) is 0.198 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the P1520ED come in?
It is listed in TO252. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the P1520ED?
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.
