SPS01N60C3 MOSFET — Specifications & Equivalents

About the SPS01N60C3

The SPS01N60C3 is an N-channel MOSFET with a drain–source voltage (V_DS) rating of 600 V, a continuous drain current (I_D) of 0.8 A and an on-resistance (R_DS(on)) of 6 Ω. It can dissipate up to 11 W and is rated to a junction temperature of 150 °C. It is supplied in the TO251-SL package.

Typical applications

With its 600 V drain–source rating the SPS01N60C3 sits in the high-voltage (offline) class of switching MOSFETs, typically found in primary-side switching in offline SMPS (flyback, forward and quasi-resonant), active PFC boost stages, half-bridge and full-bridge inverters, induction heating and electronic ballasts and BLDC and AC motor drives. The rating leaves usable margin above the ~325 V DC bus obtained by rectifying 230 VAC mains, which is why this class dominates offline power supplies.

At 0.8 A it is aimed at small-signal and light-load switching rather than power conversion.

On-resistance of 6 Ω is relatively high, so this part is better suited to low duty-cycle or low-current switching than to continuous high-current conduction.

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 25 ns and an output capacitance (C_oss) of 40 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the SPS01N60C3

A drop-in substitute for the SPS01N60C3 must be the same N-channel type and offer a drain–source rating of at least 600 V, a continuous drain current rating of at least 0.8 A and an on-resistance no higher than 6 Ω if efficiency and heat matter.

Mechanically, check the replacement against the TO251-SL 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 SPS01N60C3?

The SPS01N60C3 is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 600 V drain-source and 0.8 A continuous drain current.

What is the maximum voltage of the SPS01N60C3?

The SPS01N60C3 has a maximum drain-source voltage (Vds) of 600 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the SPS01N60C3 handle?

It is rated for 0.8 A of continuous drain current, with power dissipation limited to 11 W. Real-world capability depends on your heatsinking and ambient temperature.

What is the on-resistance of the SPS01N60C3?

On-resistance (Rds(on)) is 6 Ω. Multiply by the square of your load current to estimate conduction loss.

What package does the SPS01N60C3 come in?

It is listed in TO251-SL. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the SPS01N60C3?

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.
