Infineon Technologies DD89N16KKHPSA1

Overview

DD89N16KKHPSA1 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) 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) configurations.

For engineers reviewing the DD89N16KKHPSA1 datasheet, DD89N16KKHPSA1 pinout, DD89N16KKHPSA1 application, or DD89N16KKHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.215 °C/W per arm), surge current capability (2.4 kA @ Tvj max), on-state voltage (1.5 V @ 300 A), and pressure-contact Si pellet construction with AlN isolation.

Technical Context

This dual-arm rectifier module integrates two independent high-voltage silicon diode dies in a single press-pack housing with ceramic (AlN) internal insulation and direct copper baseplate mounting. It supports both two-pulse (B2) and six-pulse (B6) bridge topologies under forced or natural convection cooling.

Thermal performance is defined by transient junction-to-case impedance (ZthJC) with analytical R-τ network parameters, and case-to-heatsink resistance (RthCH ≤ 0.10 °C/W per arm). Electrical behavior includes 0.75 V threshold voltage (V(TO)) and 2.3 mΩ slope resistance (rT) at maximum junction temperature.

Key Specifications

Pinout & Package

DD89N16KKHPSA1 is housed in a press-pack module with two isolated anode/cathode terminals per arm (total four main terminals), mounted via M2 torque screws (4 Nm ±10%) for electrical connections and M1 torque screws (4 Nm ±15%) for mechanical clamping. Internal Si pellets use pressure-contact technology with aluminum nitride (AlN) isolation.

FAQ

What is the maximum junction temperature and how is it enforced?

The maximum junction temperature (Tvj max) is 150°C, validated under worst-case electrical and thermal conditions. It is enforced through thermal design using the specified RthJC (0.215 °C/W per arm) and RthCH (0.10 °C/W per arm), with case temperature monitored at the baseplate center. Exceeding this limit risks irreversible degradation of the Si die and AlN isolation layer.

Can DD89N16KKHPSA1 be used in parallel configurations?

Yes, but only with strict current-sharing measures: matched thermal mounting, symmetrical busbar layout, and external balancing resistors or active current control. The module's low rT (2.3 mΩ) and tight V(TO) tolerance (0.75 V) support parallel operation, though dynamic sharing requires gate-controlled pre-charging in hybrid designs.

What mounting torque values must be applied to electrical terminals?

Electrical terminal connections require M2 screws tightened to 4 Nm ±10%, as specified in the datasheet. Under-torque increases contact resistance and localized heating; over-torque risks thread stripping or deformation of the copper baseplate, compromising thermal transfer and isolation integrity.

Is isolation voltage tested per arm or across the entire module?

Isolation voltage (VISOL = 2.5 kV RMS, 1 min) is tested between each arm's anode and cathode terminals and the baseplate (case), confirming reinforced insulation per IEC 60747-1. The 3.0 kV rating applies only to module-to-module testing in stacked configurations-not per-arm isolation.
