Infineon Technologies DD89N16KAHPSA1

Overview

DD89N16KAHPSA1 from Semikron is a press-pack dual-diode rectifier module rated for 1600 V repetitive peak reverse voltage (VRRM), 89 A average on-state current (IFAVM) per arm at TC = 100°C, and 140 A RMS on-state current (IFRMSM), designed for high-power industrial AC/DC conversion in six-pulse bridge (B6) and two-pulse bridge (B2) configurations.

For engineers reviewing the DD89N16KAHPSA1 datasheet, DD89N16KAHPSA1 pinout, DD89N16KAHPSA1 application, or DD89N16KAHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.215 °C/W per arm, DC), surge current capability (2.4 kA @ Tvj max, 10 ms), threshold voltage (0.75 V), slope resistance (2.3 mΩ), and isolation test voltage (2.5 kV RMS, 1 min).

Technical Context

This dual-arm press-pack diode module implements a common-cathode configuration with silicon pellets mounted via pressure contact on an AlN ceramic base. It supports both B2 and B6 rectifier topologies with validated thermal performance under forced-air (KM14 + Papst 4650) and natural convection cooling.

Transient thermal impedance ZthJC is characterized analytically across seven RC network elements (e.g., R₁ = 0.005 °C/W, τ₁ = 40 µs), enabling accurate loss and temperature modeling for pulsed-load applications up to 150 °C maximum junction temperature.

Key Specifications

FAQ

What is the maximum allowable case temperature for DD89N16KAHPSA1?

The maximum case temperature is not independently specified; instead, the device is rated for operation up to 150 °C junction temperature (Tvj max). Case temperature depends on thermal design: at IFAVM = 89 A and DC conduction, TC must be ≤100 °C to maintain Tvj ≤150 °C given RthJC = 0.215 °C/W. Derating curves on page 6 of the datasheet define TC limits versus IFAVM for different conduction angles.

Does DD89N16KAHPSA1 support both B2 and B6 rectifier topologies?

Yes-pages 7–8 of the datasheet provide separate ID vs. TA derating curves for B2 (two-pulse) and B6 (six-pulse) bridge configurations. The module's dual-anode, common-cathode structure is inherently compatible with both, and thermal models (ZthCA) are validated for each under natural and forced cooling conditions with KM14 heatsinks.

How is isolation verified for DD89N16KAHPSA1?

Isolation is verified per IEC 60747-5-2: it withstands 2.5 kV RMS at 50 Hz for 1 minute (page 1, "Isolations-Prüfspannung"), with internal AlN ceramic providing the primary barrier. Creepage distance is 15 mm, and the module is qualified for use in pollution degree 2 environments. No partial discharge or impulse voltage ratings are published in this datasheet.

Can DD89N16KAHPSA1 be paralleled for higher current capacity?

No-this press-pack module is not designed for parallel operation. Its V(TO) and rT parameters exhibit inherent mismatch between units, and the datasheet provides no derating guidance or layout recommendations for paralleling. For higher current, Semikron specifies larger-rated variants (e.g., DD105N16K) or multi-module series/parallel arrays with active current balancing.
