Infineon Technologies DZ600N08KHPSA1

Overview

DZ600N08KHPSA1 from Semikron (formerly K.-A. Rüther) is a press-pack, dual-diode rectifier module rated for 600 A average on-state current at TC = 100°C, 1200 V repetitive peak reverse voltage (VRRM), and 22 kA non-repetitive surge current (IFSM). It uses silicon die with AlN ceramic isolation and is designed for high-power industrial AC/DC conversion in six-pulse bridge configurations.

For engineers reviewing the DZ600N08KHPSA1 datasheet, DZ600N08KHPSA1 pinout, DZ600N08KHPSA1 application, or DZ600N08KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.078 °C/W), on-state voltage (1.40 V max at 2200 A), pressure-contact mounting, and forced-air-cooled B6 bridge current derating up to 1600 A.

Technical Context

This dual-diode module implements a single-phase, center-tapped or two-arm configuration suitable for B2 (two-pulse) and B6 (six-pulse) rectifier topologies. Its press-pack construction eliminates wire bonds and enables direct thermal coupling to heatsinks via M1 mounting screws (5 Nm torque) and M2 terminal bolts (12 Nm).

Thermal performance is defined by transient junction-to-case impedance (ZthJC) with analytical R–τ network parameters, and case-to-ambient resistance depends on cooling mode: natural (KM17, 120W) or forced (KM17 + Papst 4650 fan), supporting continuous operation up to 150°C junction temperature.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum case temperature (TC) is +150°C, aligned with the 150°C maximum junction temperature (Tvj max) and 0.078 °C/W RthJC. Operation at TC = 150°C requires strict adherence to IFAVM derating curves and verified heatsink thermal resistance (RthCH ≤ 0.02 °C/W) under forced-air cooling conditions.

Does DZ600N08KHPSA1 support paralleling multiple units?

Yes - its low slope resistance (0.215 mΩ) and matched forward voltage characteristics enable current sharing across parallel modules when used with symmetrical busbar layout, identical thermal mounting, and external balancing resistors. The datasheet specifies no inherent current-sharing limitations beyond mechanical and thermal symmetry.

Is gate drive or control logic required for this device?

No - DZ600N08KHPSA1 is an uncontrolled power diode module with no gate or control terminals. It conducts automatically when forward-biased and blocks when reverse-biased, requiring no external timing signals, drivers, or bias circuitry. Its operation is fully passive and determined solely by applied voltage polarity and magnitude.

What is the insulation test voltage and how is it applied?

The insulation test voltage is 3.6 kV RMS at 50 Hz for 1 second between all terminals and the isolated AlN baseplate. This test verifies dielectric integrity under transient overvoltage conditions and confirms compliance with IEC 60747-2 for power semiconductor devices, ensuring safe operation in grounded systems up to 1200 V DC bus applications.
