Product details
Overview
DD435N34KHPSA1 from Infineon Technologies is a press-pack rectifier diode module with dual-arm configuration, rated for 3400 V repetitive peak reverse voltage (VRRM), 435 A average forward current at TC = 100 °C (IFAVM), and 14.5 kA non-repetitive surge current (IFSM). It features electrically insulated AlN baseplate, 0.6 mΩ slope resistance (rT), and 0.078 K/W junction-to-case thermal resistance - deployed in high-power industrial drive rectification.
For engineers reviewing the DD435N34KHPSA1 datasheet, DD435N34KHPSA1 pinout, DD435N34KHPSA1 application, or DD435N34KHPSA1 equivalent, key selection criteria include VRRM tolerance (3400 V), thermal performance under forced-air cooling, pressure-contact reliability for >150 °C junction operation, and mechanical mounting torque specifications (M1: 6 Nm, M2: 12 Nm).
Technical Context
This dual-arm rectifier module uses silicon die with pressure-contact interconnection to eliminate wire bonds, enabling high-current handling and robust thermal cycling performance. Its electrically insulated aluminum nitride (AlN) baseplate provides 3.6 kV RMS insulation test voltage and supports direct heatsink mounting without additional isolation hardware.
The device operates across -40 °C to +150 °C case temperature range and delivers stable conduction characteristics up to 150 °C junction temperature (Tvj max), with threshold voltage (VT0) of 0.84 V and on-state voltage (vF) ≤1.71 V at 1200 A. Transient thermal impedance data supports precise loss modeling for B2 and B6 bridge configurations.

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 MDD435-3400 | Same VRRM (3400 V) and IFAVM (435 A), but uses copper-molybdenum baseplate (RthJC = 0.085 K/W) and lower I²t (920 kA²s) | Less suitable for high-surge environments like drive short-circuit events due to reduced I²t margin | Select when cost sensitivity outweighs surge robustness requirements and existing heatsink design accommodates higher RthJC |
| Mitsubishi CM400DY-34A | Higher VRRM (3400 V), lower IFAVM (400 A at TC=100°C), and higher VT0 (0.92 V); uses solder-bonded die | Requires derating in continuous 435 A applications and exhibits shorter thermal cycle lifetime than pressure-contact construction | Select only if legacy board layout mandates identical footprint and thermal interface geometry |
Compared with MDD435-3400 and CM400DY-34A, DD435N34KHPSA1 offers superior surge robustness (1.05 MA²s), lower conduction loss (0.84 V VT0), and extended thermal cycling life - making it preferred for mission-critical industrial rectification where reliability trumps marginal cost savings.

FAQ
What is the maximum allowable case temperature for continuous operation?
The DD435N34KHPSA1 supports continuous operation up to +150 °C case temperature (Tc op), as specified in its datasheet. This rating assumes proper heatsink attachment with ≤0.02 K/W case-to-heatsink thermal resistance (RthCH) and adherence to M2 terminal torque (12 Nm) to maintain thermal interface integrity under vibration.
Does this module require external gate drive or control circuitry?
No - DD435N34KHPSA1 is an uncontrolled rectifier diode module with no gate or control terminals. It conducts automatically when forward-biased and blocks when reverse-biased. No driver, biasing, or timing circuitry is needed, unlike thyristor or IGBT-based modules.
Can it be used in parallel configurations for higher current capacity?
Parallel operation is not recommended without active current-sharing measures. Although both arms have matched RthJC and rT, dynamic forward voltage mismatch during transient loading can cause uneven current division. For >435 A systems, series stacking or using multiple independent modules with individual heatsinks is preferred.
What is the creepage distance and why does it matter for PCB layout?
The creepage distance is 19 mm, measured between high-voltage terminals and the insulated baseplate. This value determines minimum spacing requirements on mounting surfaces and adjacent conductive structures to prevent surface tracking under humid or contaminated conditions - critical for compliance with IEC 61800-5-1 in drive applications.
