Infineon Technologies DD710N16KHPSA2

Overview

DD710N16KHPSA2 from Infineon Technologies is a press-pack rectifier diode module with dual-arm configuration, rated for 1600 V repetitive peak reverse voltage (VRRM), 710 A average forward current (IFAVM) at TC = 100°C, and 26 kA non-repetitive surge current (IFSM); used in high-power industrial drive rectification where thermal stability and electrical isolation are critical.

For engineers reviewing the DD710N16KHPSA2 datasheet, DD710N16KHPSA2 pinout, DD710N16KHPSA2 application, or DD710N16KHPSA2 equivalent, key selection criteria include junction-to-case thermal resistance (0.062 K/W per arm), threshold voltage (0.75 V), slope resistance (0.145 mΩ), insulated baseplate compliance (Class I, EN 61140), and M2 terminal torque specification (12 Nm).

Technical Context

This dual-arm press-pack diode module employs silicon die with pressure-contact interconnection to eliminate wire bonds and solder layers, enabling high reliability under thermal cycling and mechanical stress. Its electrically insulated AlN-ceramic baseplate provides 3.6 kV RMS insulation test voltage (1 sec) and supports direct mounting to liquid-cooled heatsinks.

The device operates across -40°C to +150°C case temperature range with maximum junction temperature of 150°C. Thermal impedance modeling includes analytical ZthJC transient data for Θ = 30°–180° conduction angles, supporting accurate loss and temperature prediction in six-pulse (B6) and two-pulse (B2) bridge topologies.

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 thermal properties table. Operation at this limit requires strict adherence to the 710 A IFAVM rating at TC = 100°C - actual current must be derated using the provided TC vs. IFAVM curves (e.g., ~580 A at TC = 130°C for Θ = 180°). Exceeding TC = 150°C risks irreversible degradation of the pressure-contact interface.

Can DD710N16KHPSA2 be used in series or parallel configurations?

Yes - its dual-arm architecture and matched electrical parameters (vF, rT, recovery) support parallel operation of arms within one module or series connection of multiple modules. For parallel use, forced current sharing via busbar symmetry and identical thermal mounting is mandatory; for series, active voltage balancing circuits are required due to VRRM tolerance (±0 V spec, but practical mismatch <5% under matched conditions).

What is the recommended terminal torque for electrical connections?

The datasheet specifies 12 Nm ±10% for M2 electrical terminals. This torque ensures low-resistance contact (<0.1 mΩ added resistance) while avoiding thread stripping or ceramic cracking. Use calibrated torque tools and verify contact resistance post-assembly; re-torque after thermal cycling if initial measurement exceeds 0.2 mΩ.

Does the insulated baseplate require additional thermal interface material?

No - the AlN baseplate is designed for direct metal-to-metal contact with heatsinks. However, a thermally conductive, electrically insulating grease (e.g., Dow Corning TC-5022) is recommended to fill microscopic air gaps and reduce effective RthCH by up to 15%. Avoid silicone-based pastes incompatible with AlN; never use electrically conductive TIMs.
