What this MOSFET is and where it fits
The TPIC2322LD is a small-signal N-channel MOSFET from the * series, intended for low-current switching and load-control applications where a through-hole or Bulk-packaged device is called for. It is classified as a signal-level transistor, not a power-switching part — think gate drive, logic-level translation, or relay pre-driver stages rather than motor or solenoid direct-drive. The device carries an active lifecycle status, so it remains a valid line item for new designs and production builds without near-term LTB risk.
RoHS status — a procurement gate
The TPIC2322LD is RoHS non-compliant. For BOMs that require lead-free assembly or must meet EU RoHS directive exemption limits, this part will not pass incoming inspection. If a lead-free equivalent is needed, the design team will need to evaluate a different small-signal N-channel MOSFET with a compliant termination finish — the TPIC2322LD itself does not offer a RoHS variant in the * series as listed.
Sourcing and supply posture
For designs that require a second-source hedge, the small-signal N-channel MOSFET class has many functional equivalents from other manufacturers — but no pin-compatible direct cross is listed in the official record for this specific order code.
