Typical applications
With its 1000 V drain–source rating the APT10026JFLL sits in the ultra-high-voltage class of switching MOSFETs, typically found in industrial ignition and igniter circuits, high-voltage pulse generators and electrostatic and CRT deflection stages. Ratings at this level demand careful creepage/clearance and insulation design on the PCB.
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 a rise time of 8 ns and an output capacitance (Coss) of 1270 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.
Choosing a replacement for the APT10026JFLL
A drop-in substitute for the APT10026JFLL must be the same N-channel type and offer a drain–source rating of at least 1000 V, a continuous drain current rating of at least 30 A and an on-resistance no higher than 0.26 Ω if efficiency and heat matter.
Mechanically, check the replacement against the SOT227 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 APT10026JFLL?
The APT10026JFLL is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 1000 V drain-source and 30 A continuous drain current.
What is the maximum voltage of the APT10026JFLL?
The APT10026JFLL has a maximum drain-source voltage (Vds) of 1000 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.
How much current can the APT10026JFLL handle?
It is rated for 30 A of continuous drain current, with power dissipation limited to 595 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the APT10026JFLL?
On-resistance (Rds(on)) is 0.26 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the APT10026JFLL come in?
It is listed in SOT227. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the APT10026JFLL?
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.
