Typical applications
With its 60 V drain–source rating the SPP18P06PH 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.
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 5.8 ns and an output capacitance (Coss) of 230 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.
Choosing a replacement for the SPP18P06PH
A drop-in substitute for the SPP18P06PH must be the same P-channel type and offer a drain–source rating of at least 60 V, a continuous drain current rating of at least 18.7 A and an on-resistance no higher than 0.13 Ω if efficiency and heat matter.
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 SPP18P06PH?
The SPP18P06PH is a P-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 60 V drain-source and 18.7 A continuous drain current.
What is the maximum voltage of the SPP18P06PH?
The SPP18P06PH 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 SPP18P06PH handle?
It is rated for 18.7 A of continuous drain current, with power dissipation limited to 81.1 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the SPP18P06PH?
On-resistance (Rds(on)) is 0.13 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the SPP18P06PH 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 SPP18P06PH?
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.
