Product details
Overview
DD435N40KHPSA1 from Infineon Technologies is a press-pack rectifier diode module with dual-arm configuration, rated for 4000 V repetitive peak reverse voltage (VRRM), 435 A average forward current (IFAVM) at TC = 100 °C, and 14.5 kA non-repetitive surge current (IFSM); used in high-power industrial drive rectification and UPS systems.
For engineers reviewing the DD435N40KHPSA1 datasheet, DD435N40KHPSA1 pinout, DD435N40KHPSA1 application, or DD435N40KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.078 K/W per module), threshold voltage (0.84 V), slope resistance (0.6 mΩ), electrically insulated AlN baseplate, and pressure-contact silicon pellet construction for high-reliability power conversion.
Technical Context
This dual-arm rectifier module employs pressure-contact technology to eliminate wire bonds and solder joints, enabling robust operation under high di/dt and thermal cycling stress. Its electrically insulated aluminum nitride (AlN) baseplate supports direct mounting to heatsinks while maintaining galvanic isolation up to 3.6 kV RMS.
The device delivers stable conduction characteristics across -40 °C to +150 °C case temperature range, with transient thermal impedance optimized for both natural and forced cooling configurations (e.g., KM17 heatsink). It is designed for B2 (two-pulse) and B6 (six-pulse) bridge topologies in medium- to high-voltage DC link generation.
Key Specifications

Pinout & Package
DD435N40KHPSA1 is housed in an industrial-standard press-pack module with electrically insulated AlN baseplate and dual-arm configuration. Terminals are accessed via M1 (6 Nm) mechanical and M2 (12 Nm) electrical mounting screws; no traditional pin numbering applies due to symmetrical, bolt-down terminal architecture.

|---|---|---|
| Anode 1 / Cathode 1 | Arm 1 AC input / DC output node | High-current path for one leg of B2/B6 rectifier bridge; rated for full IFAVM and IFSM. |
| Anode 2 / Cathode 2 | Arm 2 AC input / DC output node | Independent second arm enabling dual-phase or split-bridge operation; electrically isolated from Arm 1. |
| Baseplate | Thermal interface & electrical isolation barrier | AlN-ceramic substrate providing 3.6 kV RMS insulation and direct thermal coupling to heatsink. |

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 |
|---|---|---|---|
| DD435N34KHPSA1 | Lower VRRM (3400 V), identical IFAVM (435 A), same package and thermal specs. | Suitable for 690 VAC systems but not 1000 VAC or higher DC link designs. | Select when system peak reverse voltage remains ≤3400 V to reduce cost without compromising current or thermal performance. |
| DD600N34KHF | Higher IFAVM (600 A), same VRRM (3400 V), larger footprint and weight (1900 g). | Required for higher continuous current demands; not drop-in compatible due to mechanical dimensions. | Choose for future-proofing or parallel operation where >435 A per arm is needed, accepting increased size and mounting requirements. |
Compared with DD435N34KHPSA1 and DD600N34KHF, DD435N40KHPSA1 uniquely balances 4000 V blocking capability with 435 A rating in a standard press-pack form factor-making it optimal for 1000 V-class DC links where voltage margin is critical but current demand stays within 435 A per arm.

FAQ
What is the maximum allowable junction temperature for DD435N40KHPSA1?
The maximum junction temperature (Tvj max) is 150 °C, as specified in the official Infineon datasheet revision 3.0. This limit applies under all operating conditions including repetitive and non-repetitive stress. Thermal design must ensure that junction temperature remains below this value using the provided RthJC (0.078 K/W) and RthCH values, along with heatsink selection and cooling method.
Does DD435N40KHPSA1 require external heat sinking?
Yes, mandatory external heatsinking is required. The module has no internal thermal management; its RthJC of 0.078 K/W refers to junction-to-case only. Effective thermal performance depends on proper mounting torque (M2 terminals: 12 Nm ±10%), thermal interface material, and heatsink design-validated for KM17-type coolers under natural or forced airflow per datasheet transient thermal models.
Is the baseplate of DD435N40KHPSA1 electrically isolated?
Yes, the baseplate is electrically insulated using aluminum nitride (AlN) ceramic with a rated insulation test voltage of 3.6 kV RMS (1 sec, 50 Hz). This allows direct mounting to grounded heatsinks without additional isolation hardware, simplifying mechanical integration while maintaining safety and functional isolation in high-voltage systems.
Can DD435N40KHPSA1 be used in single-phase rectifier topologies?
Yes, it supports single-phase configurations including B2 (two-pulse) bridge rectification. Datasheet graphs explicitly define maximum output current (ID) versus thermal resistance (RthCA) for both B2 and B6 topologies. In B2 use, one arm handles full AC cycle conduction, so derating may apply depending on duty cycle and cooling-refer to page 8 thermal derating curves.
