Product details

The Infineon AIGB40N65F5ATMA1 is a 650 V, 40 A NPT (Non-Punch-Through) IGBT in a TO-263-3 (D²Pak) surface-mount package. It is a discrete switch designed for medium-power applications where a robust, easy-to-parallel IGBT is needed. The NPT structure gives a positive temperature coefficient on Vce(sat), which means multiple devices share current evenly when paralleled — a practical advantage for higher-current stages. Typical deployment includes motor-drive inverter output stages, PFC boost converters, induction heating, and UPS systems where the 650 V rating provides margin on a 400 V DC bus.

Package and thermal — the D²Pak footprint

The part is supplied in the PG-TO263-3-2 package, which is the standard D²Pak (TO-263) with two leads and a large exposed collector tab. Surface-mount assembly on a copper-inlaid PCB with adequate via stitching under the tab is expected for the 40 A rating; the tab carries the collector current and the bulk of the thermal path. The package accepts standard reflow profiles and is MSL-rated per Infineon's handling notes.

ROHS3 compliance is confirmed, so the part meets current EU substance restrictions without exemption.

Frequently asked questions

What is the difference between NPT and Trench IGBT?

NPT (Non-Punch-Through) IGBTs, like this device, use a uniform drift region that gives a positive temperature coefficient on Vce(sat). This makes them inherently easier to parallel — current sharing improves as the devices warm up. Trench IGBTs use a vertical gate structure to reduce on-state voltage and switching losses at high frequencies, but their temperature coefficient can be flatter or even negative in some operating regions, requiring more careful gate-drive matching when paralleled. For motor-drive and PFC stages where paralleling is common, NPT is often the preferred topology.

What is the closest pin-compatible alternative to AIGB40N65F5ATMA1?

No official cross-reference or second-source part is listed in the available documentation. Within Infineon's own TrenchStop and HighSpeed families there are parts in the same D²Pak package with similar voltage and current ratings, but their switching characteristics and gate-drive requirements differ. For a true pin-compatible drop-in, verify the gate charge, Vce(sat), and switching times against your design's gate-drive and thermal budget before substituting.
