The PSMN8R5-108ES: The part number encodes the on-resistance family — the '8R5' suffix points to an 8.5 mOhm typical RDS(on) class — making it suited for high-efficiency, low-loss switching where conduction losses dominate the thermal budget. This is the part to specify for new designs that need a reliable, long-term supply channel.
Bulk packaging and assembly fit
For high-volume pick-and-place lines, confirm that the feeder and reel compatibility are not required; bulk suits prototype builds, repair stock, and low-to-medium volume production where hand-loading or tube feeding is acceptable.
Sourcing reality: active production, quoted to order
The PSMN8R5-108ES is listed as Active by the manufacturer. No last-time-buy window or phase-out has been announced.
