DD540N22K IGBT Power Module: Comprehensive Guide for Industrial Automation Applications
On this page
The seven photographs show six DD540N22K-labelled power modules arranged in two cartons, plus close views of one module. The label carries Infineon and POWERBLOCK wording and a two-diode circuit diagram. That diagram differs from the IGBT identity in the retained article title. The 10 March 2026 entry describes the items as domestic-made with branding; manufacturer markings on a label do not resolve that provenance conflict.
Identification and delivery details
The readable side label states DD540N22K and depicts two diode symbols connected through three numbered power terminals. The black moulded housing has three large threaded terminal pads and a metal base with four corner mounting holes. No gate-control connection is identified in the visible label diagram. This photo evidence supports describing the labelled circuit as a diode arrangement rather than importing collector/emitter specifications from the old IGBT text.
Surface scratches are visible on the metal base and terminal pads. The entry does not state a clear new/used grade or a warranty period, and those terms should be agreed before purchase. The digits 540 and 22 in the model are not treated as measured current or voltage ratings. The photos contain no device test sheet, junction-temperature conditions, isolation measurement or independent manufacturer traceability.
| Item | Evidence |
|---|---|
| Visible model | DD540N22K |
| Label branding | Infineon; POWERBLOCK |
| Visible circuit | Two diode symbols and three numbered power terminals |
| Connections | Three threaded metal terminal pads; no identified gate connection in label diagram |
| Mounting | Metal base with four corner holes |
| Quantity | Six recorded; six modules visible across two cartons |
| Provenance conflict | Entry says domestic-made with branding; visible Infineon label does not independently authenticate manufacture |
| Condition and warranty | Not clearly specified in entry; surface marks visible; confirm terms |
| Delivery date and record weight | 10 March 2026; 1 kg recorded, not a photographed weighing |
| Electrical limits | Current, voltage and thermal limits not established from the photographed markings |

Identification follows the readable label and circuit symbol. The record's domestic-production wording is disclosed alongside the label branding. No current or voltage value is inferred from the model digits or inherited from the earlier article.
Matching this part
Provide the complete existing module code, required circuit topology, terminal numbering and mounting drawing. Obtain the exact datasheet and agreed electrical test evidence for the supplied device before selecting voltage, current or cooling conditions.
Confirm manufacturer/source requirements, condition and warranty in writing. Match base flatness, insulation, terminal arrangement and the host's installation procedure; visual similarity alone does not establish an electrically equivalent replacement.
Photos and recorded media
Recorded inspection clip. The clip is retained as delivery evidence; no performance measurement is inferred from it.
