APT25M100J Equivalent & Substitute Parts Reference

Part Overview

The APT25M100J, manufactured by Microchip Technology, is a Power MOS 8™ series N-channel MOSFET. It features a drain-source voltage (Vdss) of 1000 V, continuous drain current (Id) of 25A at 25°C (Tc), Rds On of 330mOhm at 18A and 10V, and a maximum power dissipation of 545W (Tc). The device is supplied in a chassis-mountable ISOTOP® (SOT-227-4, miniBLOC) package. It holds an active product status, is RoHS3 compliant, and has an unlimited moisture sensitivity level (MSL 1). When sourcing or replacing this component, engineers must evaluate alternative MOSFETs within transistors, FETs, and MOSFETs categories possessing equivalent electrical and mechanical characteristics. Alternate models are necessary when considering lead time, inventory, or supply continuity.

Substitute Part Grouping Explanation

Substitute part selection is based strictly on the following parameters: MOSFET N-Channel configuration, the same or higher Drain to Source Voltage (Vdss), equal or higher Current - Continuous Drain (Id) @ 25°C, comparable or lower Rds On (Max) under similar test conditions, equivalent Vgs (Max), compatible package style (SOT-227-4, miniBLOC or equivalent), same mounting type (chassis mount), and matching compliance statuses (RoHS3, MSL 1, REACH). Only parts sharing these characteristics can be grouped as substitutes within the transistors, FETs, and MOSFETs category.
