JBE112Q MOSFET — Specifications & Equivalents

About the JBE112Q

The JBE112Q is a MOSFET with a drain–source voltage (V_DS) rating of 110 V and a continuous drain current (I_D) of 220 A. It can dissipate up to 284 W and is rated to a junction temperature of 150 °C. It is supplied in the TO263 package.

At a glance

• Type: MOSFET
• Max drain–source voltage (V_DS): 110 V

• Power dissipation (P_D): 284 W
• Max junction temperature (T_J): 150 °C
• Package: TO263

Typical applications

With its 110 V drain–source rating the JBE112Q sits in the medium-voltage class of switching MOSFETs, typically found in 48 V and 96 V distribution systems, solar and telecom power stages, DC motor drives and intermediate-bus DC-DC converters.

The 220 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 1494 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the JBE112Q

A drop-in substitute for the JBE112Q should match its polarity and offer a drain–source rating of at least 110 V and a continuous drain current rating of at least 220 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 JBE112Q?

The JBE112Q is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 110 V drain-source and 220 A continuous drain current.

What is the maximum voltage of the JBE112Q?

The JBE112Q has a maximum drain-source voltage (Vds) of 110 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the JBE112Q handle?

It is rated for 220 A of continuous drain current, with power dissipation limited to 284 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the JBE112Q 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 JBE112Q?

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.
