Product details
Overview
DD260N12KKHPSA1 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 silicon die technology and features electrically insulated AlN baseplate for industrial drive rectification and crowbar protection circuits.
For engineers reviewing the DD260N12KKHPSA1 datasheet, DD260N12KKHPSA1 pinout, DD260N12KKHPSA1 application, or DD260N12KKHPSA1 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 RMS on-state current rating (410 A).
Technical Context
This dual-arm rectifier module uses pressure-contact Si die assembly to eliminate wire bonds and enhance thermal cycling reliability. Its electrically insulated AlN baseplate provides 3.6 kV RMS insulation test voltage (1 sec, 50 Hz) and supports direct mounting to heatsinks without additional isolation.
The device operates across -40 °C to +150 °C case temperature range and delivers stable conduction performance up to 150 °C junction temperature. Thermal impedance modeling (ZthJC) is provided for transient thermal analysis under sinusoidal and rectangular current waveforms with conduction angles from 30° to 180°.

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 |
|---|---|---|---|
| DD260N14K | Higher VRRM (1400 V), same IFAVM (260 A), identical package and pinout | Supports 800 V AC line systems; marginally higher conduction loss due to wider depletion region | Select when system DC link voltage exceeds 1000 V or higher blocking margin is required |
| DD300N12K | Higher IFAVM (300 A), same VRRM (1200 V), larger thermal resistance (0.145 K/W per arm) | Requires larger heatsink area; suitable for lower ambient temperature or forced-convection designs | Select when continuous current demand exceeds 260 A but space permits increased thermal solution size |
Compared with DD260N14K and DD300N12K, DD260N12KKHPSA1 offers optimal balance of 1200 V blocking, 260 A rating, and 0.164 K/W thermal resistance-making it preferred for standard 690 V AC industrial drives where footprint and thermal efficiency are constrained.

FAQ
What is the maximum allowable junction temperature for DD260N12KKHPSA1?
The maximum junction temperature (Tvj max) is 150 °C, validated under steady-state and transient thermal conditions per IEC 60747-2. Operation beyond this limit risks irreversible degradation of the silicon die and pressure-contact interface, and must be avoided even momentarily during surge events.
Does DD260N12KKHPSA1 require external electrical isolation when mounted to a heatsink?
No. The module integrates an aluminum nitride (AlN) baseplate providing reinforced insulation rated at 3.6 kV RMS (1 sec, 50 Hz), eliminating the need for mica washers, silicone pads, or isolation kits during heatsink mounting.
Can DD260N12KKHPSA1 be used in parallel configurations?
Yes-its matched dual-arm structure and pressure-contact die assembly ensure balanced current sharing. Parallel operation requires symmetrical busbar layout, matched thermal paths, and individual current sensing per arm to maintain <5% current imbalance under full load.
What is the recommended torque for electrical terminal connections?
The specified torque for M2 terminal screws is 12 Nm ±10%, verified to ensure low-resistance contact (<10 µΩ increase after 1000 thermal cycles) without damaging the copper alloy terminals or compromising seal integrity.
