Infineon Technologies DZ600N18KHPSA1

Overview

DZ600N18KHPSA1 from K.-A. Rüther is a 1800 V repetitive peak reverse voltage, 600 A average on-state current, press-pack silicon rectifier diode module with AlN internal insulation and dual-anode/dual-cathode bipolar configuration for high-power AC/DC conversion in industrial drive systems. It delivers 1.40 V max forward voltage at 2200 A and supports forced-air or natural cooling on KM17 heatsinks.

For engineers reviewing the DZ600N18KHPSA1 datasheet, DZ600N18KHPSA1 pinout, DZ600N18KHPSA1 application, or DZ600N18KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.0745 °C/W), surge current rating (19,000 A @ Tvj max), I²t capability (1,805,000 A²s), and pressure-contact Si-pellet construction for high-reliability power conversion.

Technical Context

This module implements a bipolar, dual-die press-pack rectifier architecture with two independent anode–cathode arms in a single housing, enabling B2 (two-pulse) and B6 (six-pulse) bridge configurations. Its AlN ceramic isolation and 0.215 mΩ slope resistance support stable conduction under high di/dt transients up to 10,000 A/µs.

Thermal performance is defined by transient junction-to-case impedance ZthJC with analytical R–τ elements (e.g., R₁ = 0.00194 °C/W, τ₁ = 0.000732 s), and case-to-heatsink resistance of 0.02 °C/W. Maximum junction temperature is rated at 150 °C with storage and operating range from –40 °C to +150 °C.

FAQ

What is the mounting torque specification for DZ600N18KHPSA1 mechanical terminals?

The mechanical mounting torque for M1 screws is 5 Nm ±15%, ensuring uniform pressure across the Si-pellet interface without die fracture. This value is validated for copper baseplate contact and AlN insulation integrity under thermal cycling from –40 °C to +150 °C, and must be applied using calibrated torque tools to maintain RthJC ≤ 0.0745 °C/W.

Does DZ600N18KHPSA1 support natural convection cooling?

Yes-DZ600N18KHPSA1 is explicitly rated for natural air cooling on KM17 (120 W) heatsinks, with thermal data provided for RthCA = 0.020–0.030 °C/W depending on ambient temperature. Its 0.0745 °C/W RthJC and 900 g mass enable stable junction temperatures ≤150 °C at 600 A IFAVM under TA ≤ 45 °C with no forced airflow.

What is the insulation test voltage and duration for this module?

The insulation test voltage is 3.0 kV RMS at 50 Hz for 1 minute between case and terminals, per datasheet page 1. This validates dielectric integrity of the AlN internal insulation layer under long-term humidity and pollution conditions, meeting IEC 60747-9 requirements for industrial power modules.

Can DZ600N18KHPSA1 be used in phase-controlled rectifier circuits?

Yes-its electrical characteristics (including vF, rT, and Qr behavior) are characterized across conduction angles from 60° to 180°, and thermal curves explicitly reference Θ = 60° rec, 120° rec, and 180° sin waveforms. It is qualified for use with thyristor-gated control in B2/B6 configurations where precise timing alignment between arms is maintained.
