Infineon Technologies DD260N16KKHPSA1

Overview

DD260N16KKHPSA1 from Infineon Technologies is a press-pack rectifier diode module with dual anti-parallel diode configuration, rated for 1600 V repetitive peak reverse voltage (VRRM), 260 A average forward current (IFAVM) at TC = 100 °C, and 9500 A non-repetitive surge current (IFSM). It employs pressure-contact technology and aluminum nitride (AlN) baseplate insulation for high-reliability industrial drive rectification.

For engineers reviewing the DD260N16KKHPSA1 datasheet, DD260N16KKHPSA1 pinout, DD260N16KKHPSA1 application, or DD260N16KKHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.164 K/W per arm), threshold voltage (0.70 V), slope resistance (0.68 mΩ), and electrically insulated 50 mm baseplate compliance with IEC 61140 Class 1 insulation.

Technical Context

This dual-diode press-pack module supports two-pulse (B2) and six-pulse (B6) bridge rectifier topologies in high-power AC/DC conversion. Its pressure-contact construction eliminates wire bonds and solder joints, enabling robust thermal cycling performance and stable conduction under 150 °C maximum junction temperature.

The device delivers 1.32 V maximum forward voltage at 800 A and 150 °C, with 30 mA maximum reverse leakage at rated VRRM. Thermal impedance modeling includes analytical ZthJC parameters for transient thermal analysis across conduction angles from 30° to 180°, supporting accurate loss and temperature prediction in motor drives and UPS systems.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum allowable case temperature (TC) is +150 °C, as specified in the datasheet's operating temperature range (Tc op: –40 °C to +150 °C). At this temperature, the device maintains its rated 260 A IFAVM with appropriate heatsink design and thermal interface material to sustain 0.164 K/W RthJC.

Does DD260N16KKHPSA1 require gate drive or control signals?

No - DD260N16KKHPSA1 is an uncontrolled power diode module with no gate or control terminals. It conducts automatically when forward-biased above its 0.70 V threshold voltage and blocks current when reverse-biased up to 1600 V, making it suitable for passive rectification only.

Can this module be used in parallel configurations?

Yes - the module supports parallel operation when matched units are used with symmetrical busbar layout, identical thermal mounting pressure, and current-sharing inductors. Derating to 90% of total rated current is recommended to ensure balanced sharing due to inherent Vf tolerances.

What is the creepage distance and why does it matter?

The creepage distance is 17 mm, measured across the insulated AlN baseplate surface between terminals. This value ensures safe isolation under pollution degree 2 conditions and enables compliance with IEC 61800-5-1 for adjustable speed drives operating at up to 1000 V AC mains input.
