APT50M38JLL

Single FETs, MOSFETs Overview

The APT50M38JLL is a single N-channel Power MOSFET from the POWER MOS 7® series, manufactured by Microchip Technology. It features a 500V drain-source voltage (Vdss) and a continuous drain current of 88A at case temperature (Tc). The device exhibits a maximum on-resistance (Rds(on)) of 38 mΩ at Vgs = 10V and Id = 44A. It is housed in an ISOTOP® package (SOT-227-4/miniBLOC) designed for chassis mounting. Maximum power dissipation is rated at 694W at Tc, with an operating junction temperature range of -55°C to +150°C.

Single FETs, MOSFETs Procurement Notes

Verify the specific suffix JLL against official Microchip documentation to confirm pinout and electrical tolerances. Ensure the procurement channel provides valid traceability and authenticity guarantees. Confirm that the ISOTOP® package dimensions match the mechanical constraints of the target chassis mount assembly before finalizing orders.

Single FETs, MOSFETs Selection Notes

Select this component when high voltage isolation and efficient thermal transfer are required. The 38 mΩ Rds(on) offers a balance between conduction loss and cost for 500V applications. Consider the 88A continuous current rating relative to the actual cooling capacity of the system's heatsink infrastructure.

Single FETs, MOSFETs Part Context

This part belongs to the APT50MxxJLL family of discrete power MOSFETs. These devices utilize advanced planar trench gate technology to achieve superior performance compared to older generation MOSFETs. The ISOTOP® packaging distinguishes them from standard TO-247 or TO-220 packages by offering enhanced thermal conductivity through the backside.

Single FETs, MOSFETs Replacement Considerations

Direct replacements include APT50M50JLL and APT50M38JLL variants within the same ISOTOP® form factor. Verify that substitute parts maintain compatible Vdss, Rds(on), and package mounting hole patterns to ensure mechanical interchangeability without redesigning the PCB or heatsink interface.
