JMSH0606AK MOSFET — Specifications & Equivalents

About the JMSH0606AK

The JMSH0606AK is a MOSFET with a drain–source voltage (V_DS) rating of 60 V and a continuous drain current (I_D) of 90 A. It can dissipate up to 83 W and is rated to a junction temperature of 150 °C. It is supplied in the TO252 package.

At a glance

• Type: MOSFET
• Max drain–source voltage (V_DS): 60 V
• Max continuous drain current (I_D): 90 A
• Power dissipation (P_D): 83 W
• Max junction temperature (T_J): 150 °C
• Package: TO252

Typical applications

With its 60 V drain–source rating the JMSH0606AK 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.

The 90 A current rating puts it in high-current territory, where conduction loss (I² × R_DS(on)) and thermal design usually matter more than switching loss. Budget for adequate copper area and a heatsink.

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

Choosing a replacement for the JMSH0606AK

A drop-in substitute for the JMSH0606AK should match its polarity and offer a drain–source rating of at least 60 V and a continuous drain current rating of at least 90 A.

Mechanically, check the replacement against the TO252 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 JMSH0606AK?

The JMSH0606AK is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 60 V drain-source and 90 A continuous drain current.

What is the maximum voltage of the JMSH0606AK?

The JMSH0606AK 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 JMSH0606AK handle?

It is rated for 90 A of continuous drain current, with power dissipation limited to 83 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the JMSH0606AK come in?

It is listed in TO252. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the JMSH0606AK?

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.
