Infineon Technologies DD540N22KHPSA2

Overview

DD540N22KHPSA2 from Infineon Technologies is a press-pack rectifier diode module with dual-arm configuration, rated for 2200 V repetitive peak reverse voltage (VRRM), 540 A average forward current (IFAVM) at TC = 100 °C, and 16.5 kA non-repetitive surge current (IFSM); used in high-power industrial drive rectification where thermal stability and electrical isolation are critical.

For engineers reviewing the DD540N22KHPSA2 datasheet, DD540N22KHPSA2 pinout, DD540N22KHPSA2 application, or DD540N22KHPSA2 equivalent, key selection criteria include junction-to-case thermal resistance (0.078 K/W per module), threshold voltage (0.78 V), slope resistance (0.31 mΩ), electrically insulated baseplate, and pressure-contact die attachment for high-cycle reliability.

Technical Context

This dual-arm rectifier module employs silicon die with pressure-contact interconnection-eliminating wire bonds and enabling robust thermal and mechanical performance under high-current, high-temperature operation. It supports both two-pulse (B2) and six-pulse (B6) bridge configurations with validated derating curves for case temperature versus output current.

Thermal behavior is characterized by analytical transient impedance ZthJC models (five RC elements), with DC RthJC of 0.078 K/W per module and additional ΔZth corrections for sinusoidal and rectangular conduction angles (Θ = 30°–180°). Insulation withstands 3.6 kV RMS (1 sec) per IEC 61140 Class 1 requirements.

Key Specifications

FAQ

What is the maximum allowable junction temperature for DD540N22KHPSA2?

The maximum junction temperature (Tvj max) is 150 °C, as specified in the Infineon technical information document revision 3.1. This limit applies under all operating conditions including repetitive and non-repetitive stress, and must be maintained via proper heatsinking and thermal interface design to ensure long-term reliability.

Does DD540N22KHPSA2 require forced cooling?

No, forced cooling is not mandatory but highly recommended for continuous operation above 300 A. Natural convection is insufficient due to 540 A rating and 0.078 K/W RthJC; typical designs use finned aluminum heatsinks with thermal paste and airflow ≥2 m/s to maintain TC ≤ 100 °C at full load.

Can DD540N22KHPSA2 be used in parallel configurations?

Parallel operation is not recommended without active current balancing. The module lacks integrated current-sharing features, and mismatch in V(TO) and rT between units can cause uneven current distribution. For higher current needs, select a higher-rated single module (e.g., DD750N series) instead of paralleling.

What is the creepage distance specification for this module?

The creepage distance is 19 mm, measured across the insulated baseplate surface between high-voltage terminals and the mounting surface. This value complies with IEC 61140 Class 1 insulation requirements and supports safe operation in pollution degree 2 environments per IEC 60664-1.
