600 V N-channel MOSFET with AEC-Q101 qualification
This is an AEC-Q101 qualified device from the automotive-grade series, designed for high-voltage power conversion in vehicle systems — DC-DC converters, PFC stages, auxiliary supplies, and motor drive inverters where the 600 V drain-source voltage handles the bus rail. These switching figures suit moderate-frequency hard-switched topologies in the 50-150 kHz range where the designer balances conduction loss against switching loss.
TO-220FP full-pack — no insulating washer needed
The TO-220FP full-pack package (also called TO-220 isolated tab) is a deliberate choice for high-voltage automotive designs. This saves a BOM line, reduces assembly steps, and eliminates the thermal interface failure point that a mica washer introduces. Maximum power dissipation is 30 W at case temperature, derated to the junction temperature limit of 150°C. The through-hole mounting suits boards where the heatsink is on the opposite side of the PCB or where mechanical retention from the bolt-through tab is preferred over surface-mount clip attachment. Gate drive voltage is specified at 10 V for both maximum and minimum Rds(on), with an absolute maximum gate-source voltage of ±25 V.
This means STMicroelectronics no longer manufactures this order code, and no last-time-buy window remains open. New-production requirements must be sourced through independent distribution channels — surplus inventory, broker stock, or franchise-distributor remaining shelf stock. For a buyer filling a BOM line in production, the obsolete status means this part cannot be specified into a new design unless the design team has already qualified it and the remaining lifecycle of the product can be covered by secured surplus inventory. Any new design-in should target a current-production replacement.
