Product details
Overview
DD285N02KHPSA1 from Semikron is a dual-arm press-pack rectifier diode module rated for 285 A average on-state current per arm, 400 V repetitive peak reverse voltage, and 9.5 kA non-repetitive surge current at 10 ms. It features silicon pellet construction with AlN internal insulation, 0.085 °C/W junction-to-case thermal resistance per module, and is designed for high-power industrial AC/DC conversion in six-pulse bridge configurations.
For engineers reviewing the DD285N02KHPSA1 datasheet, DD285N02KHPSA1 pinout, DD285N02KHPSA1 application, or DD285N02KHPSA1 equivalent, key selection criteria include RMS on-state current capability (450 A), transient thermal impedance profile (ZthJC analytical model provided), pressure-contact mechanical interface, and forced/natural cooling derating curves for B2/B6 topologies.
Technical Context
This device implements a dual-diode, common-cathode press-pack configuration with two independent arms housed in a single insulated metal baseplate. Each arm supports full-wave rectification with 150 °C maximum junction temperature and 3.6 kV RMS insulation test voltage at 50 Hz for 1 second.
Thermal performance is defined by analytical R–τ network models for both junction-to-case (ZthJC) and case-to-ambient (ZthCA) transient impedances under natural and forced cooling. Electrical behavior includes 1.15 V max forward voltage at 800 A and 0.75 V threshold voltage at Tvj max.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse blocking voltage per arm; defines usable DC bus voltage range in B6 rectifiers. |
| IFAVM | 285 A - Average forward current per arm at TC = 100 °C; basis for continuous power rating in industrial drives. |
| IFRMSM | 450 A - RMS on-state current limit; determines I²t withstand and thermal cycling capability under real-world load profiles. |
| IFS M | 9.5 kA - Non-repetitive surge current at tP = 10 ms, Tvj = 25 °C; critical for short-circuit ride-through in motor drives. |
| RthJC | 0.085 °C/W - Max junction-to-case thermal resistance per module; enables precise heatsink sizing using analytical ZthJC models. |
| vF max | 1.15 V - Forward voltage at iF = 800 A and Tvj = 150 °C; directly impacts conduction loss and efficiency in high-current rectification. |
| VISOL | 3.6 kV - Insulation test voltage (50 Hz, 1 s); certifies isolation integrity for 690 VAC input systems with safety margin. |
Pinout & Package
DD285N02KHPSA1 uses a dual-arm press-pack package with three main terminals: two anodes (A1, A2) and one common cathode (K). The module mounts via M1 screw terminals (5 Nm torque) for mechanical fixation and M2 terminals (12 Nm torque) for high-current electrical connections. Internal Si pellets use pressure contact and AlN ceramic insulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Arm 1 | Connects to AC phase input in B6 topology; carries half-cycle current during positive half-wave conduction. |
| A2 | Anode of Arm 2 | Connects to second AC phase input; enables dual-arm interleaving for reduced ripple and balanced thermal loading. |
| K | Common Cathode | Output node for DC bus; requires low-inductance, high-current busbar connection to minimize switching stress. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-arm common-cathode topology | Enables compact six-pulse rectifier design with shared cathode output and independent anode routing. |
| AlN ceramic internal insulation | Provides 3.6 kV isolation strength and stable thermal conductivity across -40 to +150 °C operating range. |
| Pressure-contact Si pellet assembly | Eliminates wire bonds and solder layers, improving thermal fatigue life and current sharing under high di/dt. |
| Transient thermal impedance model (ZthJC) | Supplied as analytical R–τ network (7-element) for accurate pulsed-load thermal simulation in drive control firmware. |
| Mounting torque specification | M1 = 5 Nm ±15% (mechanical), M2 = 12 Nm ±10% (electrical) ensures repeatable thermal contact and low-resistance interfaces. |

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 |
|---|---|---|---|
| DD300N04K | 400 V VRRM, 300 A IFAVM, higher IFRMSM (480 A), same press-pack package but different RthJC (0.078 °C/W). | Suitable for higher RMS loads but requires updated thermal modeling due to altered ZthJC coefficients. | Select when system RMS current exceeds 450 A and thermal margin must be increased by ≥5%. |
| DD250N06K | 600 V VRRM, 250 A IFAVM, lower surge rating (8.3 kA), identical mounting interface and insulation rating. | Better suited for 690 VAC input systems where higher blocking voltage is mandatory over current capacity. | Choose for applications requiring extended reverse voltage margin in medium-voltage industrial grids. |
Compared with DD285N02KHPSA1, DD300N04K offers higher RMS current headroom at identical voltage rating, while DD250N06K trades average current for enhanced 600 V blocking-making the original optimal for 400 V, 285 A continuous-duty rectification with proven thermal predictability.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum allowable case temperature is not specified as a standalone limit; instead, continuous operation is defined by IFAVM = 285 A at TC = 100 °C. Case temperature must remain ≤100 °C under rated average current, with junction temperature capped at 150 °C. Derating curves in the datasheet show allowable IFAVM versus TC for natural and forced cooling.
Does DD285N02KHPSA1 support reverse conduction or bidirectional current flow?
No. DD285N02KHPSA1 is a unidirectional rectifier diode module with two anodes and one common cathode. It conducts only from anode to cathode and blocks reverse current up to 400 V (VRRM). Bidirectional operation requires complementary anti-parallel thyristor or IGBT modules, not supported by this device.
How is thermal resistance measured-per arm or per module?
RthJC is specified per module (0.085 °C/W max) and per arm (0.170 °C/W max) under 180° sine conduction. The per-module value applies when both arms operate simultaneously with balanced current sharing; per-arm values apply during single-arm testing or asymmetrical loading, as confirmed in the thermal characterization section of the datasheet.
Can this module be used in a single-phase bridge (B2) configuration?
Yes. Although optimized for three-phase B6 rectification, DD285N02KHPSA1 supports B2 operation using one arm for each half-bridge leg. The datasheet provides separate derating curves for B2 topology, showing maximum output current versus ambient temperature and RthCA, confirming validated use in single-phase high-power supplies.
