Product details
Overview
DD260N18KHPSA1 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); used in high-reliability industrial drive rectification and crowbar protection circuits.
For engineers reviewing the DD260N18KHPSA1 datasheet, DD260N18KHPSA1 pinout, DD260N18KHPSA1 application, or DD260N18KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.164 K/W per arm), electrically insulated AlN baseplate, pressure-contact die attachment, and 150 °C maximum junction temperature under continuous operation.
Technical Context
This dual-arm rectifier module employs pressure-contact silicon die mounting on an aluminum nitride (AlN) insulated baseplate, enabling high thermal cycling endurance and low parasitic inductance. Its design supports both two-pulse (B2) and six-pulse (B6) bridge configurations with validated transient thermal impedance models for accurate loss calculation across conduction angles (Θ = 30°–180°).
Electrical isolation is certified to 3.6 kV RMS (1 sec, 50 Hz), and mechanical mounting uses M12 terminal torque (12 Nm ±10%) and M6 baseplate torque (6 Nm ±15%). The module operates over –40 °C to +150 °C case temperature range with 800 g typical mass and 17 mm creepage distance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1800 V - Maximum repetitive reverse blocking voltage per arm; defines safe DC bus voltage margin in 1500 V systems. |
| IFAVM | 260 A @ TC = 100 °C - Continuous average forward current rating per arm; determines heatsink sizing for steady-state operation. |
| IFSM | 9500 A @ tP = 10 ms - Non-repetitive surge current capability; enables short-circuit withstand in motor drive fault conditions. |
| RthJC | 0.164 K/W per arm - Junction-to-case thermal resistance; sets minimum thermal interface conductance required for 150 °C Tj max. |
| V(TO) | 0.70 V - Threshold voltage at max Tj; used with rT = 0.68 mΩ to calculate forward drop (vF = V(TO) + iF × rT) for loss modeling. |
| Visol | 3.6 kV RMS (1 sec) - Basic insulation test voltage; certifies compliance with IEC 61140 Class 1 safety requirements. |
| Tvj max | 150 °C - Absolute maximum junction temperature; constrains allowable power dissipation and cooling design. |
Pinout & Package
DD260N18KHPSA1 is housed in an industrial-standard press-pack module with electrically insulated AlN baseplate (Class 1 insulation), 50 mm × 50 mm footprint, and dual-arm topology. Terminals are arranged as two isolated anode/cathode pairs (A1/K1 and A2/K2), each supporting independent current paths. Mounting uses four M6 screws for baseplate fixation and two M12 studs for main terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Arm 1 | High-side connection point for first diode arm; carries full phase current in B2/B6 rectifier topologies. |
| K1 | Cathode of Arm 1 | Low-side return path for Arm 1; electrically isolated from baseplate via AlN substrate. |
| A2 | Anode of Arm 2 | Second independent anode terminal; enables parallel or interleaved rectifier configurations. |
| K2 | Cathode of Arm 2 | Second cathode terminal; allows dual-output or split-bus rectification without shared ground reference. |
| Baseplate | Thermal & Mechanical Interface | Electrically insulated (3.6 kV RMS), thermally conductive AlN surface; requires thermal interface material and controlled torque (6 Nm) for reliable heat transfer. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, high-current rectifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MDD260-18N1 | Same VRRM (1800 V), IFAVM (260 A), but higher RthJC (0.18 K/W) and no AlN baseplate (ceramic-coated copper). | Requires additional isolation hardware for grounded heatsinks; less suitable for space-constrained UPS chassis. | Select when cost sensitivity outweighs thermal performance and isolation simplicity. |
| Mitsubishi CM100DY-24H | Lower VRRM (1200 V), same IFAVM (260 A), integrated heatsink-mounting holes, but no pressure-contact construction. | Limited to 1000 V DC bus systems; reduced surge robustness due to solder-based die attach. | Select only for lower-voltage industrial drives where 1800 V margin is unnecessary. |
Compared with MDD260-18N1 and CM100DY-24H, DD260N18KHPSA1 offers superior thermal resistance, built-in isolation, and pressure-contact reliability-making it optimal for mission-critical 1500 V systems requiring long-term stability without auxiliary insulation.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum allowable case temperature (TC) is +150 °C, aligned with the 150 °C maximum junction temperature (Tvj max) and thermal resistance RthJC = 0.164 K/W. Operation above this limit risks irreversible degradation of the pressure-contact die interface and AlN insulation layer.
Does DD260N18KHPSA1 require external gate drive or control signals?
No - DD260N18KHPSA1 is an uncontrolled power diode module with no gate or control terminals. It conducts current automatically when forward-biased beyond its threshold voltage (V(TO) = 0.70 V) and blocks reverse voltage up to 1800 V (VRRM).
Can this module be used in parallel configurations for higher current capacity?
Yes - the dual-arm architecture and matched electrical parameters (V(TO), rT, RthJC) allow paralleling of multiple DD260N18KHPSA1 units. Current sharing must be verified using busbar symmetry, equal-length interconnects, and thermal coupling to avoid imbalance.
Is the baseplate electrically isolated from the semiconductor die terminals?
Yes - the baseplate features basic insulation (Class 1 per IEC 61140) using aluminum nitride (AlN), rated for 3.6 kV RMS (1 sec). This allows direct mounting to grounded heatsinks without additional isolation hardware while maintaining functional safety separation.
