JMSH1509PG MOSFET — Specifications & Equivalents
About the JMSH1509PG
The JMSH1509PG is an N-channel MOSFET with a drain–source voltage (VDS) rating of 150 V, a continuous drain current (ID) of 89 A and an on-resistance (RDS(on)) of 0.0099 Ω. It can dissipate up to 156 W and is rated to a junction temperature of 150 °C. It is supplied in the PDFN5X6-8L package.

Typical applications
With its 150 V drain–source rating the JMSH1509PG 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 89 A current rating puts it in high-current territory, where conduction loss (I² × RDS(on)) and thermal design usually matter more than switching loss. Budget for adequate copper area and a heatsink.
The low 0.0099 Ω on-resistance keeps conduction loss down, which suits synchronous rectification and continuous high-current paths.
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 45 ns and an output capacitance (Coss) of 328 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.
Choosing a replacement for the JMSH1509PG
A drop-in substitute for the JMSH1509PG must be the same N-channel type and offer a drain–source rating of at least 150 V, a continuous drain current rating of at least 89 A and an on-resistance no higher than 0.0099 Ω if efficiency and heat matter.
Mechanically, check the replacement against the PDFN5X6-8L 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 JMSH1509PG?
The JMSH1509PG is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 150 V drain-source and 89 A continuous drain current.
What is the maximum voltage of the JMSH1509PG?
The JMSH1509PG has a maximum drain-source voltage (Vds) of 150 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.
How much current can the JMSH1509PG handle?
It is rated for 89 A of continuous drain current, with power dissipation limited to 156 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the JMSH1509PG?
On-resistance (Rds(on)) is 0.0099 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the JMSH1509PG come in?
It is listed in PDFN5X6-8L. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the JMSH1509PG?
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.
