Product details
Overview
DZ1070N26KHPSA1 from Infineon Technologies is a press-pack rectifier diode module rated for 2600 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, 0.17 mΩ slope resistance (rT), and 0.0435 K/W junction-to-case thermal resistance-used in high-power industrial drive rectification.
For engineers reviewing the DZ1070N26KHPSA1 datasheet, DZ1070N26KHPSA1 pinout, DZ1070N26KHPSA1 application, or DZ1070N26KHPSA1 equivalent, key selection criteria include VRRM derating at elevated junction temperature, pressure-contact reliability under cyclic thermal stress, RMS current capability in six-pulse bridge configurations, and thermal interface torque specification (18 Nm for terminals, 6 Nm for mounting).
Technical Context
This double-sided press-pack diode module integrates two series-connected silicon die per arm using pressure-contact technology-enabling high-current conduction without wire bonds or solder joints. It supports both two-pulse (B2) and six-pulse (B6) bridge topologies with validated I²t ratings of 8.4×10⁶ A²s (tP = 10 ms, Tvj = 25°C) and 6.125×10⁶ A²s (tP = 10 ms, Tvj = Tvjmax).
Thermal performance is defined by transient ZthJC curves and DC RthJC = 0.0435 K/W per module, with case-to-heatsink resistance RthCH ≤ 0.01 K/W. The electrically insulated AlN baseplate meets IEC 61140 Class I insulation, rated for 3.6 kV RMS/1 sec and 3 kV RMS/1 min isolation test voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 2600 V - Maximum repetitive reverse blocking voltage per diode arm; defines usable DC bus voltage in B6 rectifiers up to ~1700 VDC. |
| IFAVM | 1070 A @ TC = 100°C - Average forward current rating; determines continuous power handling in forced-air or liquid-cooled drives. |
| IFSM | 41000 A @ tP = 10 ms - Non-repetitive surge current; supports short-circuit ride-through in motor drive inverters. |
| vF / rT | 0.8 V threshold + 0.17 mΩ slope - Low conduction loss enables <1.52 V forward drop at 3400 A peak; critical for efficiency in multi-MW UPS systems. |
| RthJC | 0.0435 K/W - Junction-to-case thermal resistance; sets minimum heatsink requirement for 160°C max junction temperature. |
| Weight | 2750 g - Heavy-duty mechanical construction suitable for fixed-mount industrial installations with vibration resistance ≥50 m/s². |
Pinout & Package
Package: Press-pack double-side cooled module with insulated AlN baseplate, 70 mm × 70 mm footprint, M1 mounting screws (6 Nm), and M2 terminal studs (18 Nm). No discrete pins-current enters/exits via top and bottom copper terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Top Terminal (Anode) | Anode connection for one diode arm | Carries full forward current in half-bridge leg; requires low-inductance busbar interface. |
| Bottom Terminal (Cathode) | Cathode connection for same diode arm | Electrically isolated from baseplate; forms return path in B6 bridge configuration. |
| Baseplate | Thermal & electrical reference plane | AlN-insulated surface rated 3.6 kV RMS; serves as heatsink interface and safety barrier. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact die attachment | Eliminates bond-wire fatigue and solder voiding-enables >10⁵ thermal cycles at ΔT = 100 K in drive applications. |
| Class I basic insulation (AlN) | Provides reinforced isolation between terminals and heatsink; eliminates need for external insulating pads in grounded-chassis systems. |
| Validated B6 bridge derating curves | Supports 5000 A output current with RthCA = 0.025 K/W ambient-to-case thermal resistance-verified for UPS rectifier stacks. |
| High I²t surge capacity | 8.4×10⁶ A²s withstand at 25°C junction-ensures fault clearance time compatibility with 50–60 Hz AC line protection devices. |

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 |
|---|---|---|---|
| DD900S26K2 | Same VRRM (2600 V) and IFAVM (900 A), but lower IFSM (32 kA) and higher RthJC (0.052 K/W). | Lower surge margin limits use in fault-prone utility interconnects; requires larger heatsink for same thermal load. | Select when cost sensitivity outweighs surge robustness and thermal density requirements. |
| SKKT1000/26E | Higher IFAVM (1000 A), identical VRRM, but uses solder-bonded die and non-insulated baseplate (requires separate insulator). | Not directly interchangeable due to missing integrated AlN insulation; adds assembly complexity and creepage risk. | Select only when existing heatsink design accommodates external insulation and thermal interface layers. |
Compared with DD900S26K2 and SKKT1000/26E, DZ1070N26KHPSA1 delivers superior thermal density (0.0435 K/W), integrated Class I isolation, and highest surge margin-making it optimal for new-build high-reliability drive and UPS platforms where maintenance access is constrained.

FAQ
What is the maximum allowable junction temperature for DZ1070N26KHPSA1?
The maximum junction temperature (Tvj max) is 160°C, validated across all operating conditions including IFSM surges and continuous conduction. This rating is used in thermal modeling with the provided ZthJC transient curves and DC RthJC = 0.0435 K/W to determine heatsink requirements for target ambient temperatures.
Does DZ1070N26KHPSA1 require external insulation when mounted to a grounded heatsink?
No. The module features an AlN-based electrically insulated baseplate meeting IEC 61140 Class I insulation, rated for 3.6 kV RMS/1 sec. It may be mounted directly to a conductive heatsink without additional insulating pads or sleeves, simplifying mechanical integration.
What is the recommended terminal torque for electrical connections?
The specified torque for M2 terminal studs is 18 Nm ±10%. This value ensures low-resistance, vibration-resistant contact while avoiding thread deformation or stud fracture. Torque must be applied using a calibrated tool after verifying stud cleanliness and plating integrity.
Can DZ1070N26KHPSA1 be used in single-phase rectifier configurations?
Yes-it supports single-phase B2 (two-pulse) bridge operation, with published derating curves showing 1200 A output at RthCA = 0.02 K/W. However, its optimized thermal and surge performance is fully realized in three-phase B6 configurations where current sharing and thermal distribution are balanced across arms.
