Product details
Overview
DD285N04KHPSA1 from Semikron is a press-pack dual-diode rectifier module rated for 400 V repetitive peak reverse voltage, 285 A average on-state current at 100°C case temperature, and 450 A RMS on-state current, designed for high-power industrial AC/DC conversion in six-pulse bridge configurations.
For engineers reviewing the DD285N04KHPSA1 datasheet, DD285N04KHPSA1 pinout, DD285N04KHPSA1 application, or DD285N04KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.082 °C/W per arm), surge current capability (9.5 kA @ 10 ms), on-state voltage (1.15 V max at 800 A), and isolation test voltage (3.6 kV RMS).
Technical Context
This dual-diode module implements a symmetrical, pressure-contact silicon die configuration with aluminum nitride (AlN) internal insulation and is optimized for forced-air-cooled six-pulse rectifier bridges in medium-voltage drive systems. It supports conduction angles up to 180° sine and operates with maximum junction temperature of 150°C.
The device delivers low forward voltage drop (1.15 V) and slope resistance (0.4 mΩ) at full-rated current, enabling high-efficiency power conversion in applications requiring >500 kW output. Its transient thermal impedance profile (ZthJC) is characterized for DC and rectified waveforms, supporting accurate thermal modeling under real-world load cycles.

Pinout & Package
DD285N04KHPSA1 is housed in a press-pack module with two isolated diode arms sharing a common baseplate. Electrical terminals are arranged as three M12 screw connections: one anode (A1), one cathode (K1), and one shared cathode/anode (common terminal for dual-arm configuration). Mechanical mounting uses M1 screws (5 Nm torque) and M2 terminal screws (12 Nm torque).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Arm 1 | Input connection for first diode arm in B6 bridge leg; carries full phase current during positive half-cycle. |
| K1 | Cathode of Arm 1 | Output node for Arm 1; tied to DC+ bus in standard six-pulse layout. |
| Common | Shared terminal (A2/K2) | Interconnect point enabling dual-arm operation; used for mid-point referencing or parallel configuration. |
Key Features
| Feature | Design Value |
|---|---|
| AlN ceramic isolation | Enables 3.6 kV RMS isolation and stable thermal performance across -40°C to +150°C ambient. |
| Pressure-contact Si pellet | Eliminates wire bonds and solder layers, improving thermal cycling reliability and reducing contact resistance. |
| Low slope resistance (0.4 mΩ) | Minimizes forward voltage rise under overload, maintaining predictable conduction loss up to 800 A. |
| Transient thermal model provided | Includes analytical ZthJC coefficients (7 R-τ pairs) for accurate dynamic thermal simulation in drive control software. |

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 |
|---|---|---|---|
| DD285N06KHPSA1 | Higher VRRM (600 V) but identical IFAVM (285 A), RthJC (0.082 °C/W), and package. | Required where system DC link exceeds 540 V or transient overvoltage risk is elevated. | Select when operating with 690 VAC mains or needing higher safety margin against line surges. |
| DD285N08KHPSA1 | 800 V VRRM, same thermal and current ratings; slightly higher vF (1.20 V) due to wider bandgap design. | Suitable for 1000 VDC systems or legacy designs specifying 800 V blocking. | Choose only if 800 V rating is mandated by system architecture-otherwise prefer lower-voltage variant for efficiency. |
Compared with DD285N04KHPSA1, the 06K and 08K variants trade off forward voltage and thermal efficiency for higher blocking voltage, making them necessary only in specific overvoltage or legacy compliance scenarios-not general-purpose upgrades.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature for continuous operation is 100°C, as specified by the IFAVM = 285 A rating. Operation above this temperature reduces average current capacity per derating curves in the datasheet, and junction temperature must not exceed 150°C under any condition.
Can DD285N04KHPSA1 be used in natural convection cooling?
Yes, but only at significantly reduced current levels. The datasheet provides thermal data for natural cooling (KM17, 60 W heatsink), showing maximum IFAVM drops to ~140 A. Forced air cooling (Papst 4650 fan) is required to achieve full 285 A rating.
Is the module RoHS-compliant and halogen-free?
Yes, DD285N04KHPSA1 complies with EU RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. This is confirmed in Semikron's official product compliance documentation and material declarations dated 2023.
How is the common terminal configured in a B6 bridge layout?
In a six-pulse bridge, the common terminal serves as the interconnection node between the two diode arms-typically wired as the cathode of Arm 1 and anode of Arm 2-enabling full-wave rectification without external busbar splitting or additional isolation components.
