Product details
Overview
DD98N25KHPSA1 from Infineon Technologies is a press-pack rectifier diode module with dual-arm configuration, rated for 2500 V repetitive peak reverse voltage (VRRM), 98 A average forward current (IFAVM) at TC = 100 °C, and 2400 A non-repetitive surge current (IFSM); used in industrial drive rectification, UPS systems, and battery charger front-ends where high reliability and electrically insulated baseplate are required.
For engineers reviewing the DD98N25KHPSA1 datasheet, DD98N25KHPSA1 pinout, DD98N25KHPSA1 application, or DD98N25KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.185 K/W per module), threshold voltage (0.82 V), slope resistance (2.0 mΩ), reverse leakage (25 mA at VRRM), and pressure-contact construction enabling high-current robustness in forced-air or natural-cooled heatsink assemblies.
Technical Context
This dual-arm rectifier module employs silicon die with pressure-contact interconnection-eliminating wire bonds and enhancing thermal cycling endurance. Its electrically insulated AlN-ceramic baseplate provides 3.0 kV RMS insulation test voltage and supports direct mounting to heatsinks without additional isolation hardware.
The device operates across -40 °C to +150 °C case temperature range with maximum junction temperature of 150 °C. Thermal impedance modeling (ZthJC) is provided for both DC and transient conduction angles (Θ = 180°), supporting accurate loss and temperature prediction in B2 and B6 bridge topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 2500 V - Maximum repetitive reverse blocking voltage per arm; defines usable DC bus voltage in 6-pulse rectifiers up to ~1700 VDC. |
| IFAVM | 98 A @ TC = 100 °C - Continuous forward current rating per arm under defined thermal conditions; determines heatsink sizing for steady-state operation. |
| IFSM | 2400 A @ tP = 10 ms - Short-circuit withstand capability; enables coordination with fast-acting fuses or circuit breakers in drive protection schemes. |
| V(TO) / rT | 0.82 V / 2.0 mΩ - Threshold voltage and slope resistance; jointly define forward conduction loss profile (VF = V(TO) + rT × IF) for efficiency calculation. |
| RthJC | 0.185 K/W per module - Junction-to-case thermal resistance; directly sets minimum required heatsink thermal resistance for safe junction temperature margin. |
| Visol | 3.0 kV RMS @ 50 Hz, 1 sec - Electrical isolation rating between baseplate and semiconductor; permits use in grounded-heatsink configurations without extra insulation. |
| Weight | 160 g - Mechanical mass influencing mounting stability and vibration resilience in rotating equipment enclosures. |
Pinout & Package
DD98N25KHPSA1 is housed in an industrial-standard press-pack module with electrically insulated AlN ceramic baseplate (20 mm thickness), two main DC terminals (anode and cathode per arm), and mechanical M1/M2 mounting interfaces. No internal signal pins-fully passive rectification structure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Arm 1 anode connection | High-side input terminal for first diode arm; carries full phase current in B6 configuration. |
| Cathode 1 (K1) | Arm 1 cathode connection | Common DC output node for Arm 1; joined with K2 to form unified positive DC bus in dual-arm parallel use. |
| Anode 2 (A2) | Arm 2 anode connection | Second arm input for complementary phase conduction; enables full-wave rectification without external paralleling. |
| Cathode 2 (K2) | Arm 2 cathode connection | Redundant cathode path; allows independent or shared DC output routing depending on topology. |
| Baseplate | Thermal & electrical reference plane | Electrically isolated (AlN), thermally conductive interface; serves as primary heat extraction path and mechanical anchor point. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact die interconnect | Eliminates bond wires and solder joints-enables >10⁵ thermal cycles and stable contact resistance under high di/dt stress. |
| Electrically insulated AlN baseplate | 3.0 kV RMS isolation withstand; removes need for insulating washers or silicone pads in heatsink mounting. |
| Dual-arm modular architecture | Two independent 98 A arms in single package-reduces PCB footprint and interconnect losses vs. discrete diode assemblies. |
| Low thermal resistance (RthJC) | 0.185 K/W per module-supports higher power density than bolt-down packages with comparable ratings. |
| Industrial-grade mechanical robustness | 160 g mass, 15 mm creepage distance, and 50 m/s² vibration resistance-certified for motor drive cabinet environments. |

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 MDD95-16N1 | Lower VRRM (1600 V), same IFAVM (95 A), higher RthJC (0.22 K/W), non-insulated copper baseplate | Requires external isolation hardware; limited to ≤1100 VDC bus applications | Select only when system voltage <1200 VDC and cost sensitivity outweighs isolation convenience. |
| Mitsubishi CM100DY-24A | Higher VRRM (2400 V), lower IFAVM (100 A @ TC=85°C), integrated NTC sensor, insulated Al₂O₃ baseplate | Includes temperature monitoring; rated at lower case temperature (85°C), requiring larger heatsink for same power | Prefer when real-time thermal feedback is needed and derating to 85°C case is acceptable. |
Compared with MDD95-16N1 and CM100DY-24A, DD98N25KHPSA1 uniquely combines 2500 V blocking, 98 A rating at 100 °C, and 3.0 kV baseplate isolation-making it optimal for compact, high-reliability 6-pulse rectifiers in harsh industrial environments without added isolation layers or thermal sensors.

FAQ
What is the maximum allowable case temperature for continuous operation?
The DD98N25KHPSA1 supports continuous operation with case temperature (TC) ranging from –40 °C to +150 °C. Its 98 A average forward current rating (IFAVM) is specified at TC = 100 °C; operation above this requires derating per the published TC vs. IFAVM curve on page 7 of the datasheet, with absolute maximum TC limited to 150 °C.
Does this module require thermal interface material when mounted to a heatsink?
Yes-despite its insulated AlN baseplate, a thermally conductive interface material (e.g., grease or phase-change pad) is required between the baseplate and heatsink surface to minimize contact thermal resistance. The specified RthCH (0.05 K/W per module) assumes optimized mounting torque (4 Nm ±15% for M1) and proper surface flatness (<5 μm roughness).
Can DD98N25KHPSA1 be used in single-phase rectifier configurations?
Yes-it can be configured in single-phase B2 (center-tapped) or B6 (full-wave bridge) topologies. Each arm operates independently; for single-phase use, one arm suffices, delivering up to 98 A average current. Dual-arm parallel connection increases current capacity but does not alter voltage rating.
Is the baseplate polarity referenced to any internal semiconductor terminal?
No-the AlN-ceramic baseplate is fully electrically isolated from both anode and cathode terminals. Its 3.0 kV RMS insulation rating applies between baseplate and all internal semiconductor elements, allowing flexible grounding schemes (e.g., floating, negative-rail, or positive-rail referenced heatsinks) without risk of shorting.
