RFT1P06E MOSFET — Specifications & Equivalents

About the RFT1P06E

The RFT1P06E is a MOSFET with a drain–source voltage (V_DS) rating of 60 V and a continuous drain current (I_D) of 1.4 A. It can dissipate up to 1.1 W and is rated to a junction temperature of 150 °C. It is supplied in the SOT223 package.

Typical applications

With its 60 V drain–source rating the RFT1P06E 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 an output capacitance (C_oss) of 175 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the RFT1P06E

A drop-in substitute for the RFT1P06E should match its polarity and offer a drain–source rating of at least 60 V and a continuous drain current rating of at least 1.4 A.

Mechanically, check the replacement against the SOT223 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 RFT1P06E?

The RFT1P06E is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 60 V drain-source and 1.4 A continuous drain current.

What is the maximum voltage of the RFT1P06E?

The RFT1P06E 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 RFT1P06E handle?

It is rated for 1.4 A of continuous drain current, with power dissipation limited to 1.1 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the RFT1P06E come in?

It is listed in SOT223. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the RFT1P06E?

This page lists 17 candidate equivalents matched on electrical ratings and package. Any replacement should meet or exceed the original voltage, current and dissipation figures and use a compatible drive level.
