Product details
Overview
DZ435N36KHPSA1 from Infineon Technologies is a press-pack rectifier diode module rated for 3600 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 employs pressure-contact silicon pellet technology with aluminum nitride (AlN) internal insulation and an electrically isolated 50 mm baseplate, designed for high-reliability industrial power conversion in drive inverters.
For engineers reviewing the DZ435N36KHPSA1 datasheet, DZ435N36KHPSA1 pinout, DZ435N36KHPSA1 application, or DZ435N36KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.078 K/W), on-state threshold voltage (0.84 V), slope resistance (0.6 mΩ), RMS on-state current rating (1100 A), and isolation test voltage (3.6 kV RMS).
Technical Context
This dual-diode press-pack module implements a single-phase, two-arm configuration with symmetrical electrical characteristics per arm. Each arm delivers 435 A average forward current at TC = 100°C and supports 3600 V blocking capability under repetitive conditions, with transient thermal impedance optimized for 180° sinusoidal conduction.
Thermal performance is defined by a maximum junction temperature of 150°C, 0.078 K/W junction-to-case resistance, and 0.02 K/W case-to-heatsink resistance. Mechanical mounting uses M1 screws (5 Nm ±15%) and M2 terminals (12 Nm ±10%), with creepage distance of 15 mm and vibration resistance up to 50 m/s² at 50 Hz.

FAQ
What is the maximum allowable case temperature for continuous operation?
The DZ435N36KHPSA1 supports continuous operation up to 150°C case temperature, with derated average forward current (IFAVM) scaling linearly from 435 A at 100°C to 700 A at 47°C. Thermal design must maintain junction temperature ≤150°C using the specified RthJC (0.078 K/W) and system-level RthCA.
Does this module require external heat sinking, and what is the recommended mounting torque?
Yes, mandatory heat sinking is required. Mounting uses M1 screws (5 Nm ±15%) for mechanical attachment and M2 terminals (12 Nm ±10%) for electrical connections. The 0.02 K/W case-to-heatsink resistance assumes flat, clean, thermally greased interface surfaces meeting ISO 2768-mK tolerances.
How does the pressure-contact construction improve reliability compared to solder-bonded alternatives?
Pressure-contact eliminates thermomechanical stress from coefficient-of-thermal-expansion mismatches, enabling >10⁶ thermal cycles without bond degradation. It also avoids void formation and intermetallic growth seen in high-temperature solder joints, resulting in stable vF and rT parameters over 20+ years of field operation.
Can this module be used in series-string configurations for higher voltage applications?
Yes, DZ435N36KHPSA1 is qualified for series stacking with active voltage balancing. Its tight VRRM tolerance (±2.5%), matched thermal impedance (0.078 K/W), and symmetric arm characteristics ensure uniform voltage sharing across 4–8 modules in 6–12 kV DC systems when paired with gate-controlled dynamic clamping circuits.
