Infineon Technologies DD380N16AHPSA1

Overview

DD380N16AHPSA1 from Semikron is a press-pack dual-arm rectifier diode module rated for 1600 V repetitive peak reverse voltage, 380 A average on-state current per arm at TC = 100°C, and 600 A RMS on-state current, designed for high-power industrial AC/DC conversion in six-pulse bridge configurations.

For engineers reviewing the DD380N16AHPSA1 datasheet, DD380N16AHPSA1 pinout, DD380N16AHPSA1 application, or DD380N16AHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.059 °C/W per arm, DC), maximum surge current (14 kA, 10 ms), forward voltage drop (1.4 V max at 1500 A and Tvj max), and pressure-contact Si pellet construction with AlN isolation.

Technical Context

This dual-arm module integrates two independent high-current diode arms in a single insulated press-pack housing, supporting both two-pulse (B2) and six-pulse (B6) bridge topologies. Each arm delivers 380 A average current with 0.32 mΩ slope resistance and 0.75 V threshold voltage at maximum junction temperature.

Thermal performance is defined by transient junction-to-case impedance (ZthJC) with analytical R-τ elements, and case-to-heatsink resistance of 0.04 °C/W per arm. It operates across -40°C to +150°C case temperature range and supports forced-air or natural convection cooling using heatsink KM17.

Key Specifications

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum allowable case temperature (Tc op) is +150°C, matching the maximum junction temperature (Tvj max = 150°C) under DC conduction. At this limit, the device sustains 380 A average current per arm only if thermal resistance to heatsink (RthCH) remains ≤0.04 °C/W and ambient cooling meets specified airflow or surface area requirements.

Can DD380N16AHPSA1 be used in a two-pulse (B2) rectifier configuration?

Yes-it supports both B2 and B6 topologies. In B2 mode, both arms operate in parallel, doubling the effective current rating to 760 A average (derated per thermal limits). The datasheet provides separate ID vs. Ptot curves for B2 on page 7, confirming validated operation with RthCA down to 0.020 °C/W.

What is the significance of the "HPSA1" suffix in the part number?

HPSA1 denotes Semikron's standard press-pack housing variant with AlN isolation, M1/M2 screw terminals, and KM17-compatible mounting geometry. It distinguishes this version from variants with alternate ceramics (e.g., BeO), different torque specs, or custom creepage distances-no functional difference in electrical ratings from base DD380N16A.

How is isolation verified for safety-critical applications?

Isolation is certified per IEC 61140 Class I (basic insulation) with 3.6 kV RMS/1 sec and 3.0 kV RMS/1 min test voltages applied between terminals and baseplate. The AlN ceramic layer provides intrinsic dielectric strength and thermal stability, and the 17 mm creepage distance complies with pollution degree 2 requirements for industrial enclosures.
