Product details
Overview
DD260N18KKHPSA1 from Infineon Technologies is a press-pack rectifier diode module with dual-arm configuration, rated for 1800 V repetitive peak reverse voltage (VRRM), 260 A average forward current (IFAVM) at TC = 100 °C, and 9500 A non-repetitive surge current (IFSM). It employs pressure-contact silicon die technology and electrically insulated AlN baseplate, designed for high-reliability industrial drive rectification.
For engineers reviewing the DD260N18KKHPSA1 datasheet, DD260N18KKHPSA1 pinout, DD260N18KKHPSA1 application, or DD260N18KKHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.164 K/W per arm), threshold voltage (0.70 V), slope resistance (0.68 mΩ), and industrial-standard mechanical mounting torque (12 Nm for terminals).
Technical Context
This dual-arm rectifier module uses pressure-contact technology to eliminate wire bonds and solder layers, enabling robust thermal cycling performance and low parasitic inductance. Its 1800 V VRRM rating supports medium-voltage DC bus applications in six-pulse and two-pulse bridge configurations.
The module integrates electrically isolated AlN ceramic baseplate (3.6 kV RMS insulation test voltage) and supports sinusoidal and rectangular conduction angles up to 180°, with transient thermal impedance ZthJC characterized analytically for precise thermal modeling under dynamic load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1800 V - Maximum repetitive reverse blocking voltage per arm; defines DC link voltage capability in 6-pulse rectifiers. |
| IFAVM | 260 A @ TC = 100 °C - Continuous average forward current per arm; sets steady-state power handling in drives and UPS systems. |
| IFSM | 9500 A @ tP = 10 ms - Non-repetitive surge current; determines short-circuit withstand capability during crowbar events. |
| V(TO) | 0.70 V max - Threshold voltage; directly impacts conduction loss at low current and influences forward voltage drop linearity. |
| rT | 0.68 mΩ max - Slope resistance; combined with IFAVM, determines on-state power loss (PFAV ≈ I² × rT + I × VTO). |
| RthJC | 0.164 K/W per arm - Junction-to-case thermal resistance; enables thermal design of heatsink interface for 150 °C max junction temperature. |
| VISOL | 3.6 kV RMS @ 50 Hz, 1 sec - Basic insulation test voltage; certifies safety isolation between terminals and baseplate per IEC 61140 Class 1. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current rectifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD260N16K | 1600 V VRRM (vs. 1800 V); identical IFAVM, IFSM, and RthJC. | Limited to ≤660 V AC line systems; unsuitable for 690 V drives or 1000 V DC bus UPS. | Select when 1600 V blocking suffices and cost optimization is prioritized over margin. |
| DD300N18K | 300 A IFAVM (vs. 260 A); same 1800 V VRRM, higher IFSM (10,500 A), and slightly higher RthJC (0.170 K/W). | Supports higher continuous current in same footprint; requires derating or enhanced cooling for equivalent thermal performance. | Choose for future-proofing or margin expansion where space-constrained upgrades are needed. |
Compared with DD260N16K, DD260N18KKHPSA1 offers 200 V higher blocking margin critical for 690 V industrial drives; versus DD300N18K, it trades 40 A current headroom for lower thermal resistance and tighter voltage drop control at nominal load.

FAQ
What is the maximum allowable junction temperature for DD260N18KKHPSA1?
The maximum junction temperature (Tvj max) is 150 °C, validated under rated IFAVM and thermal boundary conditions. Operation beyond this limit risks irreversible degradation of the silicon die and pressure-contact interface. Thermal design must ensure junction temperature remains below 150 °C under worst-case ambient and load conditions, using the provided RthJC and ZthJC data.
Does DD260N18KKHPSA1 require external heat sinking?
Yes - the module has no internal heatsink and relies entirely on external thermal management. Its RthJC of 0.164 K/W per arm assumes direct, low-thermal-resistance mounting to a heatsink using specified torque (12 Nm for terminals, 6 Nm for baseplate screws) and compatible thermal interface material. Failure to implement proper heatsinking will cause rapid thermal runaway.
Can DD260N18KKHPSA1 be used in single-phase rectifier applications?
Yes - it supports both single-phase (two-pulse) and three-phase (six-pulse) rectification. In single-phase B2 configuration, one arm handles full current while the other remains unused or paralleled; derating is required per the datasheet's IFAVM vs. conduction angle curves, especially at Θ = 60° or lower.
Is the baseplate electrically isolated from all terminals?
Yes - the AlN ceramic baseplate provides basic insulation (IEC 61140 Class 1) with 3.6 kV RMS test voltage for 1 second. All terminals (A1, K1, A2, K2) are galvanically isolated from the baseplate, enabling safe mounting to grounded heatsinks without additional insulating hardware.
