JBL101N MOSFET — Specifications & Equivalents

About the JBL101N

The JBL101N is a MOSFET with a drain–source voltage (V_DS) rating of 100 V and a continuous drain current (I_D) of 325 A. It can dissipate up to 313 W and is rated to a junction temperature of 150 °C. It is supplied in the POWER-JE-10X12 package.

Typical applications

With its 100 V drain–source rating the JBL101N 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 325 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 2099 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the JBL101N

A drop-in substitute for the JBL101N should match its polarity and offer a drain–source rating of at least 100 V and a continuous drain current rating of at least 325 A.

Mechanically, check the replacement against the POWER-JE-10X12 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 JBL101N?

The JBL101N is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 100 V drain-source and 325 A continuous drain current.

What is the maximum voltage of the JBL101N?

The JBL101N has a maximum drain-source voltage (Vds) of 100 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the JBL101N handle?

It is rated for 325 A of continuous drain current, with power dissipation limited to 313 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the JBL101N come in?

It is listed in POWER-JE-10X12. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the JBL101N?

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.
