Gate drive and switching — what 87 nC Qg means
The IPB407N30NATMA1: Total gate charge is 87 nC at 10 V gate drive. Input capacitance is 7180 pF measured at 100 V drain-source.
Temperature range and thermal budget
Junction temperature range is -55°C to 175°C — the full military-temperature span. Maximum power dissipation is 300 W at case temperature, but that number assumes an ideal heatsink; real-world dissipation depends on the thermal interface and airflow. The 175°C limit means this part can operate in a hot industrial enclosure or near a motor winding without needing a massive heatsink, as long as the average junction temperature stays under the derating curve.
Package and mounting
Surface-mount D2PAK (TO-263-3) with a single tab — the tab is the drain connection. The supplier device package is PG-TO263-3. Board layout must handle the tab's thermal path: a large copper pour on the drain node and, for high-power designs, vias to an internal or backside copper plane. The part is shipped in Tape & Reel or Cut Tape, compatible with standard pick-and-place.
Lifecycle and sourcing
The IPB407N30NATMA1 is listed as Active in production. No last-time-buy notice or NRND flag. It is ROHS3 compliant.
