Product details
Overview
DDB6U205N16LHOSA1 from Infineon Technologies is a 1600 V, 205 A dual-diode rectifier module in ISOPACK housing with glass-passivated silicon chips, rated for 120 A RMS per chip and 1600 A non-repetitive surge current, used in industrial AC-DC front-ends of UPS, motor drives, and welding equipment.
For engineers reviewing the DDB6U205N16LHOSA1 datasheet, DDB6U205N16LHOSA1 pinout, DDB6U205N16LHOSA1 application, or DDB6U205N16LHOSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.098 °C/W), forward voltage at 200 A (1.47 V max), reverse leakage (10 mA max), insulation test voltage (3.0 kV RMS), and mounting torque specification (6 Nm).
Technical Context
This dual-common-cathode rectifier module integrates two high-voltage, high-current diode chips on an Al₂O₃ ceramic substrate, enabling full-wave bridge configuration without external interconnects. Its 1600 V repetitive peak reverse voltage and 1700 V non-repetitive rating support operation in 690 V AC three-phase systems with safety margin.
The module delivers 205 A output current at TC = 100°C with DC thermal resistance of 0.078 °C/W (per module), and achieves 0.75 V threshold voltage and 2.2 mΩ forward slope resistance at Tvj max, ensuring low conduction loss under heavy load conditions.

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 |
|---|---|---|---|
| IXYS MDA205-16N1 | Same 1600 V VRRM, but 0.115 °C/W RthJC and 1.55 V vF @ 200 A | Higher conduction loss and thermal resistance require larger heatsink volume | Select when legacy IXYS footprint compatibility is mandatory and 10% higher loss is acceptable |
| Mitsubishi CM200DY-16H | 1600 V rating, 200 A Id, but uses press-fit termination and lacks specified M1/M2 torque values | No standardized mechanical mounting protocol; requires custom clamping design | Select only for retrofit into existing Mitsubishi-based systems with compatible heatsink interface |

FAQ
What is the maximum allowable case temperature for continuous operation?
The datasheet specifies TC = 100°C for 205 A output current and TC = 99°C for 208 A. Operation above 100°C requires derating per the Id vs. TC curve on page 6; sustained case temperatures beyond 100°C reduce lifetime due to accelerated thermal aging of solder joints and passivation layers.
Which heatsinks are validated for use with this module?
The datasheet explicitly lists KM 11, KM 14, KM 17, and KM 33 heatsinks. Thermal performance data (e.g., 190 A at TA = 35°C with KM 14 at VL = 45 l/s) confirms compatibility. Using unlisted heatsinks requires independent thermal simulation and validation against the 0.033 °C/W RthCK max value.
Does this module support parallel operation for higher current capacity?
No parallel operation guidance is provided in the datasheet. The module lacks integrated current-sharing features such as matched forward voltage bins or external emitter resistors. Parallel use would require individual thermal monitoring and active current balancing circuitry to prevent thermal runaway.
What is the significance of the "N B6" suffix in the part number?
"N B6" denotes Infineon's internal revision and variant code: "N" indicates the latest revision of the ISOPACK mechanical design, and "B6" identifies the specific silicon die version optimized for 1600 V blocking and 2.2 mΩ rT slope resistance, as confirmed in the characteristic values table on page 1.
