This is the board that handles gate-drive isolation, DC-link voltage sensing, and module-level protection — when it fails, the whole module drops out. It's classified as Product class C, meaning it's manufactured to order and not a stocked shelf item, so the procurement lead time is tied to the build schedule, not a warehouse bin. The Product class C designation (manufactured to order, non-returnable) means you're committing to a production slot when you order. For a line-down situation, that's the critical constraint: this isn't a same-day swap from a distributor shelf. The part is RoHS compliant since April 2018, and carries a REACH Article 33 notification for lead (CAS 7439-92-1) above 0.1% w/w — standard for power electronics with solder joints and component terminations. The 735 A rating at 500-690 V AC three-phase matches the output stage of the liquid-cooled Motor Module it belongs to — that's the phase current the IPD card's sensing and protection circuits are calibrated for. The 710 kW power figure is the motor-side output at the nominal voltage. If you're swapping this card into an existing module, verify the module's serial number range against Siemens' compatibility matrix; the IPD firmware version may need to match the Control Unit firmware for proper communication. The card itself is a PCB assembly, not a standalone drive — it has no power stage, just the logic and isolated gate-drive interface. RoHS compliance is confirmed from April 2018 production onward. The REACH candidate list disclosure for lead content is standard for this class of industrial electronics — it doesn't restrict normal handling or installation, but it does affect end-of-life disposal routing in EU jurisdictions.","metaTitle":"Siemens 6SL3356-3AG37-4AA0 SINAMICS S120 IPD Card, 735A","metaDescription":"Siemens 6SL3356-3AG37-4AA0 SINAMICS S120 replacement IPD card for liquid-cooled Motor Module, 710 kW, 500-690V 3AC, 735A.
