Product details
Overview
DD261N20KHPSA1 from Infineon Technologies is a press-pack rectifier diode module with dual-arm configuration, rated for 2200 V repetitive peak reverse voltage (VRRM), 260 A average on-state current at TC = 100 °C (IFAVM), 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 DD261N20KHPSA1 datasheet, DD261N20KHPSA1 pinout, DD261N20KHPSA1 application, or DD261N20KHPSA1 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 electrically insulated 50 mm baseplate compatibility with forced-air or liquid-cooled heatsinks.
Technical Context
This dual-arm rectifier module uses silicon die with pressure-contact interconnection-eliminating wire bonds and enabling robust current sharing and thermal cycling endurance. Its AlN-insulated baseplate provides 3.6 kV RMS insulation test voltage and supports Class I safety isolation per IEC 61140.
The device is characterized for Θ = 180° sinusoidal conduction, with transient thermal impedance ZthJC modeled analytically across seven RC network elements. Thermal derating curves define maximum IFAVM versus case temperature (TC) and total power dissipation (Ptot) under B2 (two-pulse) and B6 (six-pulse) bridge configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 2200 V - Maximum repetitive reverse blocking voltage per arm; defines usable DC bus voltage in 3-phase rectifiers up to ~1500 VDC. |
| IFAVM @ TC=100°C | 260 A - Continuous average forward current per arm at 100 °C case temperature; determines steady-state thermal design margin. |
| IFSM (tP=10 ms) | 9500 A - Non-repetitive surge current capability; supports crowbar protection and short-circuit ride-through in motor drives. |
| V(TO) / rT | 0.70 V / 0.68 mΩ - Threshold voltage and slope resistance; used with IFAV to calculate on-state loss PFAV = IFAV × V(TO) + IFAV² × rT. |
| RthJC (per arm) | 0.164 K/W - Junction-to-case thermal resistance under DC conditions; sets minimum heatsink requirement for given power dissipation. |
| Visol (RMS, 1 sec) | 3.6 kV - Insulation test voltage between terminals and baseplate; certifies isolation integrity for grounded-heatsink mounting. |
| Tvj max | 150 °C - Maximum allowable junction temperature; constrains thermal design and defines safe operating area limits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-power rectifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD260N20K | Same VRRM (2200 V) and IFAVM (260 A), but uses older packaging with lower insulation voltage (3.0 kV) and higher RthJC (0.170 K/W). | Limited to non-grounded heatsink installations; requires larger heatsink volume for same thermal margin. | Select when cost sensitivity outweighs insulation safety margin and thermal performance. |
| DD300N16K | Lower VRRM (1600 V), higher IFAVM (300 A), identical AlN baseplate and pressure-contact construction. | Suitable only for ≤1100 VDC bus systems; preferred where higher continuous current dominates over voltage headroom. | Select for 690 VAC drive applications requiring extended overload duration at elevated ambient temperatures. |
Compared with DD261N20KHPSA1, DD260N20K trades insulation safety and thermal efficiency for lower cost, while DD300N16K prioritizes current capacity over voltage rating-making each suitable only within strictly bounded system voltage and thermal envelope constraints.

FAQ
What is the recommended mounting torque for the electrical terminals?
The electrical terminals (M2 screws) require a mounting torque of 12 Nm ±10%. This ensures low-contact-resistance interconnection while avoiding thread deformation or ceramic cracking. Torque must be applied using a calibrated tool and verified during final assembly to maintain specified RthCH (0.04 K/W per arm) and prevent thermal runaway under full-load operation.
Can DD261N20KHPSA1 be used in series-string configurations?
Yes-its matched VRRM (2200 V) and tight V(TO) tolerance (±5%) enable reliable series connection without external static balancing resistors. However, dynamic voltage sharing requires matched snubber networks (RC) per arm due to inherent junction capacitance variation, especially under fast dv/dt transients exceeding 500 V/µs.
What is the creepage distance and why does it matter?
The creepage distance is 17 mm between terminals and baseplate. This meets IEC 60664-1 requirements for Pollution Degree 2 environments and ensures safe operation at 3.6 kV RMS insulation test voltage. It directly impacts PCB layout spacing, heatsink cutout dimensions, and compliance with UL/EN 62109 for power conversion equipment.
How does the transient thermal impedance affect short-duration overload capability?
ZthJC(t) data (provided as 7-element RC network) allows precise calculation of junction temperature rise during <100 ms overloads. For example, at t = 10 ms, ZthJC ≈ 0.125 K/W-enabling 2.5× IFAVM for 10 ms without exceeding Tvj max, critical for crowbar activation timing and fault ride-through validation.
