Selection Guide
Use the following criteria to confirm the DD180N16S is the right choice — or to identify the best alternative:
| Selection Criterion | Recommendation |
|---|---|
| Required VRRM ≤ 1600 V | DD180N16S is suitable ✔ |
| Required IFAV ≤ 180 A | DD180N16S is suitable ✔ |
| Required IFAV 180–200 A | Consider DD200N16K or MDD200-16N1 |
| Budget-sensitive, lower current (<160 A) | Consider SKD 160/16 with thermal derating |
| Need higher voltage (1800–2200 V) | Contact Konmask for DD180N18S / DD180N22S availability |
| Replacing legacy Eupec part | DD180N16S is the direct Infineon successor to D180N16T |
| Space-constrained / different footprint | Consult Konmask engineering support for package alternatives |

Replacement & Compatibility FAQ
Q: Can I replace DD180N16S with DD200N16K directly?
A: In most cases yes — the DD200N16K is electrically upward compatible (higher current rating, same voltage, same package). Verify heatsink thermal capacity is sufficient for the higher rated device.
Q: Is the DD180N16S RoHS compliant?
A: Yes. Infineon’s DD180N16S is manufactured in compliance with RoHS 2 (EU Directive 2011/65/EU).
Q: What is the difference between DD180N16S and D180N16T?
A: The D180N16T is the legacy Eupec designation. After Infineon acquired Eupec, the part was rebranded as DD180N16S with identical electrical characteristics and pin-compatible packaging.
Q: Do you provide test reports or CoC for this module?
A: Yes. Certificate of Conformance and inspection reports are available upon request for all orders.
Q: Can this module be used in a three-phase bridge rectifier?
A: The DD180N16S is a single-phase (dual diode) module. For a three-phase bridge, you would typically use three DD180N16S modules or a dedicated three-phase module such as the SKD series.
