Product details
Overview
DZ1070N28KHPSA1 from Infineon Technologies is a press-pack rectifier diode module rated for 2800 V repetitive peak reverse voltage (VRRM), 1070 A average forward current (IFAVM at TC = 100°C), and 41 kA non-repetitive surge current (IFSM). It features electrically insulated AlN baseplate, pressure-contact silicon pellet construction, and is designed for high-reliability industrial power conversion in drive inverters and UPS systems.
For engineers reviewing the DZ1070N28KHPSA1 datasheet, DZ1070N28KHPSA1 pinout, DZ1070N28KHPSA1 application, or DZ1070N28KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.0435 K/W), on-state voltage (max 1.52 V at 3400 A), threshold voltage (0.8 V), slope resistance (0.17 mΩ), and isolation test voltage (3.6 kV RMS/1 sec).
Technical Context
This double-diode press-pack module implements a dual common-cathode configuration with electrically isolated baseplate per IEC 61140 Class 1 insulation. Its pressure-contact technology eliminates wire bonds and solder layers, enabling robust thermal cycling performance and low parasitic inductance.
Rated for 160°C maximum junction temperature and -40°C to +150°C operating case temperature range, it supports both two-pulse (B2) and six-pulse (B6) bridge rectification topologies with validated thermal transient impedance models (ZthJC) for dynamic loss calculation under sinusoidal and rectangular conduction angles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 2800 V - Maximum repetitive reverse blocking voltage per diode arm; defines DC link voltage capability in high-power rectifiers. |
| IFAVM | 1070 A at TC = 100°C - Continuous average forward current rating; determines steady-state thermal design margin with heatsink. |
| IFSM | 41000 A at tP = 10 ms - Short-circuit surge withstand; enables coordination with fast-acting fuses in drive protection schemes. |

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 |
|---|---|---|---|
| DD900N28K | Same VRRM (2800 V) and IFAVM (900 A), but lower IFSM (36 kA) and higher RthJC (0.048 K/W). | Suitable for lower-surge environments; requires larger heatsink for equivalent thermal margin. | Select when cost sensitivity outweighs need for 41 kA surge headroom and minimal thermal resistance. |
| SKKT1000/28E | Higher IFAVM (1000 A), same VRRM, but uses solder-bonded die and non-insulated baseplate (requires isolation kit). | Requires additional insulation hardware and has reduced thermal cycling life vs. pressure-contact design. | Choose only if legacy board layout mandates screw-terminal interface and isolation can be added externally. |
Compared with DD900N28K and SKKT1000/28E, DZ1070N28KHPSA1 delivers superior surge robustness, lower thermal resistance, and integrated insulation-making it optimal for new high-reliability drive and UPS designs where maintenance intervals and lifetime cost matter.

FAQ
What is the mounting torque specification for DZ1070N28KHPSA1 mechanical and electrical terminals?
The mechanical mounting torque (M1) is 6 Nm ±15%, applied to the four corner bolts securing the module to the heatsink. The electrical terminal torque (M2) is 18 Nm ±10%, used for busbar connections to Anode 1, Anode 2, and Cathode terminals. Exceeding these values risks ceramic baseplate fracture or contact deformation.
Does DZ1070N28KHPSA1 require external thermal interface material?
Yes - a thermally conductive, electrically insulating paste or pad (e.g., silicone-based TIM with ≥3 W/m·K conductivity) must be applied between the AlN baseplate and heatsink surface. This ensures uniform thermal transfer and prevents localized hot spots, especially under high RMS current conditions.
Can DZ1070N28KHPSA1 be used in single-phase rectifier configurations?
Yes - it supports single-phase full-wave (B2) bridge operation using one anode terminal and the common cathode, with the second anode left unused or paralleled. Derating is not required, but thermal design must account for asymmetric current distribution across the internal die pair.
What is the creepage distance and why does it matter for this module?
The creepage distance is 64 mm, measured across the insulated baseplate surface between high-voltage terminals and mounting interface. This value satisfies reinforced insulation requirements for 2800 V DC systems per IEC 61800-5-1, preventing surface tracking in humid or contaminated environments typical in industrial enclosures.
