Product details
Overview
DD260N12KHPSA1 from Infineon Technologies is a press-pack rectifier diode module with dual-arm configuration, rated for 1200 V repetitive peak reverse voltage (VRRM), 260 A average on-state current (IFAVM) at TC = 100 °C, and 9500 A non-repetitive surge current (IFSM). It employs pressure contact technology and aluminum nitride (AlN) baseplate insulation for high-reliability industrial drive rectification.
For engineers reviewing the DD260N12KHPSA1 datasheet, DD260N12KHPSA1 pinout, DD260N12KHPSA1 application, or DD260N12KHPSA1 equivalent, key selection factors include junction-to-case thermal resistance (0.164 K/W per arm), threshold voltage (0.70 V), slope resistance (0.68 mΩ), and electrically insulated 50 mm baseplate mounting.
Technical Context
This dual-arm press-pack diode module uses silicon die with pressure-contact interconnection to eliminate wire bonds and solder layers, enabling robust thermal cycling performance and low parasitic inductance. Its AlN-insulated baseplate provides 3.6 kV RMS insulation test voltage and supports direct heatsink mounting without additional isolation hardware.
The device operates across -40 °C to +150 °C case temperature range, with maximum junction temperature of 150 °C. Thermal impedance modeling (ZthJC) is provided for both sinusoidal and rectangular conduction angles (Θ = 30°–180°), supporting accurate transient loss calculation in motor drive and UPS bridge topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - Maximum repetitive reverse blocking voltage per arm; defines usable DC bus voltage in 3-phase rectifiers up to ~850 V line-to-line. |
| IFAVM | 260 A @ TC = 100 °C - Continuous average forward current per arm; determines steady-state power handling in six-pulse bridge configurations. |
| IFSM | 9500 A @ tP = 10 ms - Non-repetitive surge current capability; enables crowbar protection during short-circuit events in drive inverters. |
| V(TO) | 0.70 V max - Threshold voltage at max junction temperature; used with rT to calculate forward voltage drop under load. |
| rT | 0.68 mΩ max - Slope resistance at max junction temperature; combined with IFAVM, determines conduction losses (~45 W/arm at 260 A). |
| RthJC | 0.164 K/W per arm - Junction-to-case thermal resistance under DC conditions; sets minimum heatsink requirement for thermal management. |
| VISOL | 3.6 kV RMS @ 50 Hz, 1 sec - Insulation test voltage between terminals and baseplate; certifies safety isolation for industrial mains-connected systems. |
Pinout & Package
DD260N12KHPSA1 is housed in an industrial-standard press-pack module with electrically insulated AlN baseplate and dual-arm configuration. Terminals are M12 (mechanical) and M2 (electrical) screw connections; no discrete pin numbering applies as it is a modular two-terminal-per-arm construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode Arm 1 (A1) | Forward current input terminal for first diode arm | Connects to AC phase input in B6 bridge; rated for 260 A continuous, 9500 A surge. |
| Cathode Arm 1 (K1) | Forward current output terminal for first diode arm | Joins common DC+ bus; shares thermal path with baseplate via pressure contact. |
| Anode Arm 2 (A2) | Forward current input terminal for second diode arm | Connects to second AC phase; electrically isolated from A1 by internal layout and baseplate insulation. |
| Cathode Arm 2 (K2) | Forward current output terminal for second diode arm | Joins same DC+ bus as K1; enables parallel operation or split-phase rectification. |
| Baseplate | Thermal interface and electrical reference plane | AlN-isolated metal surface (800 g mass); provides 3.6 kV isolation and 0.02 K/W case-to-heatsink resistance when torqued to 6 Nm. |
Key Features

FAQ
What is the mounting torque specification for DD260N12KHPSA1 mechanical and electrical terminals?
The mechanical mounting torque for the baseplate is 6 Nm ±15% (M1 thread), ensuring optimal thermal contact with the heatsink. Electrical terminal torque is 12 Nm ±10% (M2 thread) for reliable current conduction and vibration resistance in industrial enclosures.
Does DD260N12KHPSA1 require additional isolation hardware when mounted to a grounded heatsink?
No. The module features an aluminum nitride (AlN) electrically insulated baseplate rated for 3.6 kV RMS insulation, allowing direct mounting to grounded heatsinks without thermal pads or isolation kits while meeting IEC 61800-5-1 safety requirements.
How does the pressure contact construction improve reliability compared to soldered modules?
Pressure contact eliminates thermomechanical stress points from solder joints and bond wires, increasing thermal cycling lifetime beyond 10,000 cycles and reducing failure probability in high-vibration environments such as traction drives and wind turbine converters.
Can DD260N12KHPSA1 be used in single-phase rectifier applications?
Yes - its dual-arm structure supports single-phase full-wave rectification by connecting one arm as the main path and using the second arm for redundancy or auxiliary functions. However, derating to 180 A IFAVM is recommended due to uneven thermal distribution in non-balanced topologies.
