The TPIC5223LD is a small-signal N-channel MOSFET from Texas Instruments, designed for low-current switching and amplification roles where a compact, through-hole or bulk-packaged device is needed. As a small-signal part, it handles gate drive and load currents well below the power MOSFET tier — think relay drivers, logic-level level shifters, or pre-driver stages in industrial control boards.
Active lifecycle, but watch the RoHS flag
That means no last-time-buy pressure for ongoing BOM lines, and no scramble for a drop-in replacement. The RoHS non-compliance is the detail that trips up a procurement review. If your assembly house requires full RoHS compliance (lead-free solder, no restricted substances), this part does not clear the gate. For legacy builds with an RoHS exemption or tin-lead process, it remains a valid choice. Confirm your exemption status before committing the line.
Bulk delivery — assembly line logistics
not tape-and-reel. For a pick-and-place line, that means manual tube or tray loading unless you arrange re-reeling. For bench-level builds or repair stock, bulk is simpler and often lower per-unit cost. Factor the handling step into your assembly quote.
