Product details
Overview
DZ435N40KS01HPSA1 from Infineon Technologies is a press-pack rectifier diode module rated for 4000 V repetitive peak reverse voltage (VRRM), 435 A average forward current at 100°C case temperature (IFAVM), and 14.5 kA non-repetitive surge current (IFSM). It features a 0.84 V threshold voltage (vT0), 0.6 mΩ slope resistance (rT), and 0.078 K/W junction-to-case thermal resistance (RthJC), designed for high-reliability industrial power conversion in drive inverters and UPS systems.
For engineers reviewing the DZ435N40KS01HPSA1 datasheet, DZ435N40KS01HPSA1 pinout, DZ435N40KS01HPSA1 application, or DZ435N40KS01HPSA1 equivalent, key selection criteria include verified VRRM/VDRM rating, IFAVM derating vs. TC, transient thermal impedance ZthJC profile, pressure-contact construction integrity, and electrically insulated AlN baseplate compatibility with forced-air or natural-cooled heatsink interfaces.
Technical Context
This double-sided press-pack diode module implements silicon die with pressure-contact metallization-eliminating wire bonds and solder layers-to sustain high di/dt and mechanical robustness under cyclic thermal stress. Its 0.078 K/W RthJC and 0.02 K/W RthCH enable efficient heat extraction from dual-side cooled configurations.
The device operates across -40°C to +150°C case temperature range with 150°C maximum junction temperature (Tvj max) and supports conduction angles from 60° to 180° sinusoidal, delivering stable on-state performance up to 1200 A RMS (IFRMSM = 1100 A) under DC and rectified load profiles.
Key Specifications

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 |
|---|---|---|---|
| IXYS MDD435-4000 | Same VRRM (4000 V) and IFAVM (435 A), but uses solder-bonded die and copper-molybdenum baseplate (RthJC = 0.085 K/W). | Limited to single-side cooling; requires additional isolation hardware for grounded heatsink mounting. | Select when legacy solder-based assembly processes dominate and dual-side cooling is not required. |
| Powerex CM435N40 | Identical press-pack construction and AlN baseplate, but rated VRRM = 3600 V and IFAVM = 435 A @ TC = 90°C (not 100°C). | Lower thermal margin restricts use in high-ambient cabinets (>60°C) without forced airflow augmentation. | Select when system-level VRRM margin is ≥400 V and thermal management budget permits 10°C lower case temperature limit. |
Compared with MDD435-4000 and CM435N40, DZ435N40KS01HPSA1 delivers superior thermal performance (0.078 K/W vs. 0.085/0.082 K/W), higher VRRM headroom, and broader operational temperature range-making it optimal for space-constrained, high-reliability rectifier stacks where thermal derating and insulation integrity are critical.

FAQ
What is the maximum allowable case temperature for continuous operation?
The DZ435N40KS01HPSA1 supports continuous operation up to +150°C case temperature (Tc op), with its 435 A IFAVM rating specified at TC = 100°C. Derating curves in the datasheet show linear reduction to 700 A at TC = 47°C, confirming safe operation across the full -40°C to +150°C storage and operating range.
Does this module require thermal interface material between baseplate and heatsink?
Yes-thermal interface material (TIM) is mandatory to achieve the specified RthCH ≤ 0.02 K/W. The datasheet specifies that mounting torque for M2 terminals must be 12 Nm ±10%, and TIM selection must accommodate AlN's coefficient of thermal expansion mismatch with aluminum heatsinks to prevent delamination under thermal cycling.
Can DZ435N40KS01HPSA1 be used in parallel configurations?
Yes-its pressure-contact design and matched vF/rT characteristics enable reliable parallel operation. Infineon recommends symmetrical busbar layout, identical mounting torque on all modules, and individual current-sharing inductors to maintain <5% current imbalance at full load, as validated in application note AN2019-07.
What is the creepage distance and why does it matter for system safety?
The creepage distance is 15 mm between terminals and baseplate. This value satisfies IEC 61800-5-1 pollution degree 3 requirements for industrial environments, ensuring sufficient surface insulation path length to prevent tracking failures under humid, dusty, or conductive contamination conditions in cabinet-mounted rectifier assemblies.
