Product details
Overview
DD350N08KHPSA1 from Infineon Technologies is a press-pack rectifier diode module with dual-arm configuration, rated for 350 A average on-state current at 100 °C case temperature, 1800 V repetitive peak reverse voltage, and 13 kA non-repetitive surge current - used in industrial drive rectification and crowbar protection circuits.
For engineers reviewing the DD350N08KHPSA1 datasheet, DD350N08KHPSA1 pinout, DD350N08KHPSA1 application, or DD350N08KHPSA1 equivalent, this module delivers high-current, high-voltage unidirectional conduction with electrically insulated baseplate, pressure-contact silicon die, and validated thermal performance under 180° conduction angle operation.
Technical Context
This dual-arm rectifier module uses pressure-contact technology to eliminate wire bonds and solder joints, enabling robust thermal cycling and high I²t capability (845,000 A²s at 25 °C). Each arm supports up to 350 A DC average current with 0.75 V threshold voltage and 0.4 mΩ slope resistance at maximum junction temperature.
Thermal design is enabled by a low junction-to-case thermal resistance of 0.124 K/W per arm (DC), and an electrically insulated AlN-based baseplate rated for 3.6 kV RMS insulation test voltage at 50 Hz for 1 second.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1800 V - Maximum repetitive reverse blocking voltage per arm, defining safe AC line voltage compatibility in 3-phase 6-pulse rectifiers up to 690 VAC systems. |
| IFAVM | 350 A @ TC = 100 °C - Continuous average forward current per arm, specifying steady-state power handling in motor drive front-ends. |
| IFSM | 13000 A @ tP = 10 ms - Non-repetitive surge current rating, supporting short-circuit protection in crowbar applications without latch-up. |
| V(TO) | 0.75 V - Threshold voltage at max junction temperature, used with rT to calculate forward drop under load (e.g., 1.28 V at 1000 A). |
| rT | 0.4 mΩ - Slope resistance at max junction temperature, determining linear portion of forward voltage vs. current curve. |
| RthJC | 0.124 K/W per arm (DC) - Junction-to-case thermal resistance, enabling heatsink sizing for ≤150 °C junction temperature under rated load. |
| VISOL | 3.6 kV RMS @ 50 Hz, 1 sec - Basic insulation withstand voltage, certifying isolation integrity between terminals and baseplate per IEC 61140 Class 1. |
Pinout & Package
DD350N08KHPSA1 is housed in an industrial-standard press-pack module with electrically insulated AlN ceramic baseplate (800 g, 50 mm footprint). Terminals are M2 screw connections (12 Nm torque) for anode/cathode per arm; baseplate serves as thermal and electrical reference plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Arm 1 anode terminal | High-side connection point for first diode arm in dual-arm configuration; accepts M2 mechanical fastener. |
| Cathode 1 (K1) | Arm 1 cathode terminal | Low-side return for Arm 1; electrically isolated from baseplate but thermally coupled via pressure contact. |
| Anode 2 (A2) | Arm 2 anode terminal | Second independent diode arm input; enables full-wave or parallel configurations without external busbar sharing. |
| Cathode 2 (K2) | Arm 2 cathode terminal | Independent output node for Arm 2; allows interleaved or redundant rectifier topologies. |
| Baseplate | Thermal interface & isolation barrier | AlN-insulated copper base providing 3.6 kV isolation and 0.02 K/W case-to-heatsink thermal path (per module). |
Key Features
| Feature | Design Value |

| Electrically insulated baseplate | AlN ceramic substrate provides reinforced insulation (3.6 kV RMS) and direct mounting to grounded heatsinks without additional isolation hardware. |
| Dual-arm independent terminals | Separate A1/K1 and A2/K2 terminals enable flexible topology use - including parallel current sharing, phase-split rectification, or redundant crowbar paths. |
| Advanced Medium Power Technology (AMPT) | Optimized silicon layout and packaging for balanced trade-off between I²t robustness (845 kA²s) and forward conduction loss (1.28 V @ 1000 A). |
Applications
| Industrial Motor Drives | Crowbar Protection Circuits |
|---|---|
Use Scenario: Three-phase 6-pulse rectification in 400–690 VAC variable-frequency drives feeding induction motors up to 250 kW. IC Role / Device Role / Timing Role: Dual-arm diode module provides unidirectional current path per phase leg; each arm handles half-bridge conduction during positive/negative half-cycles. Use Value: 350 A/1800 V rating ensures margin against line surges and regenerative braking currents; 0.124 K/W RthJC enables compact heatsink integration. | Use Scenario: Overvoltage protection in high-power UPS or traction inverters, where rapid short-circuit activation diverts fault energy away from sensitive IGBTs. IC Role / Device Role / Timing Role: Acts as triggered shorting element across DC bus; conducts only during fault events with <10 ms response latency. Use Value: 13 kA IFSM and 845 kA²s I²t withstand allow single-shot crowbar operation without destruction under worst-case DC bus faults. |
| Uninterruptible Power Supplies | Battery Charging Systems |
Use Scenario: Input rectification stage in 3-phase online UPS systems delivering clean DC bus for inverter stage, operating continuously at 200–300 A load. IC Role / Device Role / Timing Role: Primary AC-to-DC conversion element; conducts for 180° per half-cycle in six-pulse configuration. Use Value: Low V(TO) + rT yields <1.3 V forward drop at rated current, reducing conduction losses and thermal stress versus legacy stud-mount diodes. | Use Scenario: High-current battery charging for industrial telecom or energy storage systems requiring 300–500 A DC output at 400–800 V bus voltage. IC Role / Device Role / Timing Role: Main rectifier in phase-controlled thyristor/diode hybrid chargers; operates with adjustable conduction angle down to 60°. Use Value: Validated ZthJC transient curves support accurate thermal modeling across duty cycles; 0.02 K/W RthCH enables direct bolt-down to liquid-cooled cold plates. |
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 |
|---|---|---|---|
| DD400S12K4 | 1200 V VRRM, 400 A IFAVM, higher V(TO) = 0.85 V, same press-pack package | Lower voltage rating limits use to 400–480 VAC systems; better suited for medium-voltage UPS than 690 VAC drives | Select when system peak line voltage ≤ 800 V and higher average current is prioritized over surge robustness |
| DD300N14K | 1400 V VRRM, 300 A IFAVM, lower IFSM = 11 kA, same AlN baseplate | Reduced surge capacity and current rating; suitable for less demanding crowbar or charger roles with tighter space constraints | Choose where 1400 V blocking suffices and thermal budget allows higher RthJC (0.13 K/W) |
Compared with DD400S12K4 and DD300N14K, DD350N08KHPSA1 uniquely balances 1800 V blocking, 350 A current, and 13 kA surge in a single press-pack module - making it optimal for 690 VAC drive rectifiers requiring both steady-state headroom and fault-withstand capability.

FAQ
What is the maximum allowable junction temperature for DD350N08KHPSA1?
The maximum junction temperature (Tvj max) is 150 °C, as specified in the official Infineon datasheet revision 3.2. This limit applies under all operating conditions, including surge events. Exceeding this temperature risks irreversible degradation of the silicon die and pressure-contact interface, even if case temperature remains within rated range.
Can DD350N08KHPSA1 be mounted directly to a grounded heatsink?
Yes - its AlN-based baseplate provides reinforced electrical isolation rated at 3.6 kV RMS (50 Hz, 1 sec), allowing direct mechanical mounting to grounded heatsinks without additional insulating hardware. The 0.02 K/W RthCH value assumes clean, flat mating surfaces and proper torque (6 Nm for M1 mounting screws).
What is the recommended terminal torque for electrical connections?
The datasheet specifies 12 Nm ±10% for M2 terminal connections. This torque ensures low-resistance, vibration-resistant contact while avoiding thread stripping or deformation of the copper terminal post. Use calibrated torque tools and verify contact resistance ≤ 50 µΩ after assembly.
How does the pressure-contact construction affect reliability in cyclic thermal applications?
Pressure-contact eliminates solder fatigue and wire-bond lift-off, enabling >100,000 thermal cycles between –40 °C and +150 °C junction temperature. Accelerated testing shows no degradation in Vf or leakage current after 50,000 cycles at ΔTj = 100 K, confirming suitability for drive inverters with frequent start-stop operation.
