Product details
Overview
DZ600N12KHPSA1 from K.-A. Rüther is a high-power, press-pack silicon rectifier diode module rated for 1200 V repetitive peak reverse voltage (VRRM), 600 A average on-state current (IFAVM) at TC = 100°C, and 1150 A RMS on-state current (IFRMSM), designed for industrial AC/DC conversion in medium-voltage drive systems and traction rectifiers.
For engineers reviewing the DZ600N12KHPSA1 datasheet, DZ600N12KHPSA1 pinout, DZ600N12KHPSA1 application, or DZ600N12KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.078 °C/W), surge current capability (22 kA @ 10 ms), on-state voltage (1.40 V @ 2200 A), and pressure-contact Si-pellet construction with AlN internal insulation.
Technical Context
This double-sided, bipolar AC rectifier module integrates two anti-parallel diode arms in a single press-pack housing, enabling bidirectional conduction control in phase-controlled rectification. It supports conduction angles from 60° to 180° sine and features transient thermal impedance modeling (ZthJC) with seven RC network elements for accurate thermal simulation under pulsed loads.
The module uses silicon die with pressure-contact metallization and aluminum nitride (AlN) ceramic isolation, delivering low slope resistance (0.215 mΩ) and threshold voltage (0.75 V) at Tvj max. Its mechanical design specifies M1 mounting torque (5 Nm ±15%) and M2 terminal torque (12 Nm ±10%), optimized for direct heatsink integration in high-reliability power converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - Maximum repetitive reverse blocking voltage per arm; defines DC link voltage rating in B6 bridge configurations. |
| IFAVM | 600 A @ TC = 100°C - Continuous average forward current per arm; sets steady-state power handling in forced-air-cooled drives. |
| IFRMSM | 1150 A - RMS forward current rating; determines I²t-based thermal stress during asymmetrical load cycles. |
| RthJC | 0.078 °C/W - Junction-to-case thermal resistance; enables precise heatsink sizing for 150°C max junction temperature operation. |
| vF max | 1.40 V @ iF = 2200 A, Tvj max - Peak forward voltage drop; directly impacts conduction loss (P = I × vF) in high-current rectifiers. |
| IFS M | 22,000 A @ tP = 10 ms, Tvj = 25°C - Non-repetitive surge current; supports short-circuit withstand in motor drive DC links. |
| Qr | Not specified in provided data - Recovered charge not listed; softness and switching behavior require external characterization. |
Pinout & Package
Package: Press-pack double-side cooled module with isolated AlN baseplate, M1 mounting holes (5 Nm), and M2 high-current terminals (12 Nm); weight 900 g, creepage distance 15 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Top) | Forward current entry point for upper arm | Pressure-contact interface; requires flat, clean heatsink surface and calibrated torque for low-resistance thermal/electrical path. |
| Cathode (Top) | Forward current exit point for upper arm | Electrically isolated from baseplate via AlN; forms one half of anti-parallel pair for AC line commutation. |
| Anode (Bottom) | Forward current entry point for lower arm | Enables dual-arm configuration without external busbar; supports B2/B6 bridge topologies with shared case reference. |
| Cathode (Bottom) | Forward current exit point for lower arm | Complements top terminals to realize full-wave rectification; symmetric layout ensures balanced thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| Double-arm anti-parallel topology | Enables bidirectional AC line control in phase-angle regulated rectifiers without external paralleling. |
| AlN ceramic internal isolation | Provides 3.6 kV RMS insulation (1 sec) and stable dielectric performance up to 150°C junction temperature. |
| Low slope resistance (rT) | 0.215 mΩ minimizes conduction loss variance across operating current range, improving efficiency predictability. |
| Transient thermal model (ZthJC) | Seven-element RC network allows accurate junction temperature prediction under non-sinusoidal, short-duration load pulses. |
| Direct heatsink mounting | M1 screw pattern and flat baseplate eliminate thermal interface materials, reducing total thermal resistance by ~0.02 °C/W vs. insulated packages. |

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 |
|---|---|---|---|
| DD600S12K4 | Lower VRRM (1200 V same), but higher IFAVM (650 A @ TC = 100°C); uses solder-bonded Si instead of pressure contact. | Requires requalification of mechanical mounting and thermal interface; unsuitable for vibration-prone traction environments. | Select only when solder-reflow assembly and lower thermal cycling stress are guaranteed. |
| SKKT600/12E | Same VRRM and IFAVM ratings, but single-arm configuration; requires external anti-parallel pairing for AC operation. | Increases PCB/busbar area and parasitic inductance; adds two extra mounting points and thermal interfaces. | Prefer only when modularity and field-replaceable arms are prioritized over compactness and thermal symmetry. |
Compared with DD600S12K4 and SKKT600/12E, DZ600N12KHPSA1 delivers superior mechanical robustness via pressure-contact construction and integrated dual-arm topology-reducing component count, thermal interface layers, and footprint by 35% in B6 bridge designs.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (TC) is +150°C, aligned with the 150°C maximum junction temperature (Tvj max). Operation at TC = 100°C enables 600 A average forward current (IFAVM), while derating applies above that point per the TC = f(IFAVM) curve on page 6 of the datasheet.
Does DZ600N12KHPSA1 require thermal interface material (TIM) between module and heatsink?
No TIM is required or recommended. The module uses direct pressure-contact mounting with flat, polished copper or aluminum heatsink surfaces. Applying TIM increases thermal resistance and risks uneven force distribution-contrary to the specified M1 mounting torque (5 Nm ±15%) and mechanical design intent.
Can this module be used in single-phase bridge (B2) configurations?
Yes-page 7 of the datasheet provides ID(B2) derating curves for two-pulse bridge operation. At TA = 45°C with natural cooling (KM17, 120W), it supports up to ~1200 A output current with RthCA = 0.030 °C/W, validated for continuous duty under defined thermal boundary conditions.
What is the insulation test voltage and duration specification?
The insulation test voltage is 3.6 kV RMS at 50 Hz for 1 second (short-time test) and 3.0 kV RMS at 50 Hz for 1 minute (long-time test), applied between terminals and baseplate. These values confirm compliance with IEC 60747-2 for high-voltage isolation integrity under factory test conditions.
