CEB603AL MOSFET — Specifications & Equivalents

About the CEB603AL

The CEB603AL is a MOSFET with a drain–source voltage (V_DS) rating of 30 V and a continuous drain current (I_D) of 25 A. It can dissipate up to 60 W and is rated to a junction temperature of 175 °C. It is supplied in the TO263 package.

Typical applications

With its 30 V drain–source rating the CEB603AL sits in the low-voltage class of switching MOSFETs, typically found in 12 V and 24 V automotive and industrial rails, synchronous buck converters, load switching and reverse-polarity protection and H-bridges for small motors.

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 360 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the CEB603AL

A drop-in substitute for the CEB603AL should match its polarity and offer a drain–source rating of at least 30 V and a continuous drain current rating of at least 25 A.

Mechanically, check the replacement against the TO263 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 CEB603AL?

The CEB603AL is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 30 V drain-source and 25 A continuous drain current.

What is the maximum voltage of the CEB603AL?

The CEB603AL has a maximum drain-source voltage (Vds) of 30 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the CEB603AL handle?

It is rated for 25 A of continuous drain current, with power dissipation limited to 60 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the CEB603AL come in?

It is listed in TO263. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the CEB603AL?

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.
