Infineon Technologies DD340N16SHPSA1

Overview

DD340N16SHPSA1 from Infineon Technologies is a dual-arm industrial rectifier diode module designed for high-power AC/DC conversion in drive inverters and UPS systems. It features 1600 V repetitive peak reverse voltage (VRRM), 330 A average on-state current at TC = 100 °C (IFAVM), 10,000 A non-repetitive surge current (IFSM), and electrically insulated Al₂O₃ baseplate. Used in three-phase six-pulse bridge rectification with forced-air or liquid-cooled heatsinks.

For engineers reviewing the DD340N16SHPSA1 datasheet, DD340N16SHPSA1 pinout, DD340N16SHPSA1 application, or DD340N16SHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.086 K/W per arm), threshold voltage (0.81 V), slope resistance (0.3 mΩ), isolation test voltage (3.6 kV RMS), and mechanical mounting torque (9 Nm for terminals).

Technical Context

This dual-diode module implements a common-cathode configuration with two independent, electrically isolated arms housed in an industrial-standard package. Each arm supports 1600 V blocking capability and handles up to 330 A DC average current under 100 °C case temperature conditions.

Thermal performance is defined by transient junction-to-case impedance (ZthJC) with analytical RC network parameters, and steady-state RthJC = 0.086 K/W per arm at 180° conduction angle. The Al₂O₃ baseplate provides reinforced insulation (Class I, IEC 61140) and 3.6 kV RMS isolation test rating.

FAQ

What is the maximum allowable junction temperature for DD340N16SHPSA1?

The maximum junction temperature (Tvj max) is 130 °C, as specified in the official Infineon technical information document revision 3.8. This limit applies under all operating conditions including surge events and must be maintained via proper heatsink design and thermal interface material selection to ensure long-term reliability.

Does DD340N16SHPSA1 support parallel operation of its two arms?

No - DD340N16SHPSA1 contains two independent diode arms in a common-cathode configuration, not paralleled internally. Each arm must be used separately in a 6-pulse bridge layout; parallel connection of arms is electrically invalid and violates the device's thermal and current-sharing specifications.

What is the recommended terminal torque for electrical connections?

The specified terminal connection torque is 9 Nm for M2 screws, with ±15% tolerance. This value ensures reliable current transfer and mechanical stability under vibration (50 m/s² at 50 Hz) while preventing thread damage or insulation cracking in the Al₂O₃ baseplate.

Can DD340N16SHPSA1 be mounted directly to a grounded aluminum heatsink?

Yes - the Al₂O₃ baseplate provides reinforced electrical isolation rated at 3.6 kV RMS, enabling direct mounting to grounded heatsinks without additional insulating hardware. Surface flatness ≤30 μm and thermally conductive dielectric grease are mandatory to maintain both thermal and isolation integrity.
