Product details
Overview
DD260N16KHPSA1 from Infineon Technologies is a press-pack rectifier diode module with dual-arm configuration, rated for 1600 V repetitive peak reverse voltage (VRRM), 260 A average on-state current (IFAVM) at TC = 100 °C, and 9500 A non-repetitive surge current (IFSM). It employs pressure-contact silicon die technology and features electrically insulated AlN baseplate, targeting high-reliability industrial drive rectification.
For engineers reviewing the DD260N16KHPSA1 datasheet, DD260N16KHPSA1 pinout, DD260N16KHPSA1 application, or DD260N16KHPSA1 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 isolation test voltage (3.6 kV RMS, 1 sec).
Technical Context
This dual-arm press-pack diode module uses silicon die mounted via pressure-contact technology-eliminating wire bonds and solder layers-to achieve robust thermal cycling performance and low parasitic inductance. Its design supports high-current DC bus rectification in multi-pulse bridge configurations (B2/B6) with defined conduction-angle-dependent thermal impedance profiles.
The module integrates basic insulation per IEC 61140 Class 1, with an AlN-ceramic baseplate providing electrical isolation up to 3.6 kV RMS. Thermal management relies on case-to-heatsink interface resistance (RthCH ≤ 0.04 K/W per arm) and transient thermal impedance modeling validated for 10 ms surge events.

FAQ
What is the maximum allowable junction temperature for DD260N16KHPSA1?
The maximum junction temperature (Tvj max) is 150 °C, as specified in the official Infineon datasheet revision 3.2. Operation beyond this limit risks irreversible degradation of the silicon die and pressure-contact interface. Thermal design must ensure that transient and steady-state junction temperatures remain within this bound under worst-case load and ambient conditions.
Does DD260N16KHPSA1 require external snubbers in B6 bridge applications?
No external snubbers are required for standard B6 rectifier operation with resistive or inductive loads, due to its inherent soft recovery characteristics and low stored charge (Qrr not specified but consistent with AMPT diode process). However, snubbers may be needed in high-di/dt switching environments or with highly capacitive DC links to suppress voltage overshoot exceeding VRRM.
Can DD260N16KHPSA1 be paralleled with other modules for higher current capacity?
Parallel operation is not recommended without active current balancing, as mismatched thermal resistance and forward voltage characteristics between units can cause current imbalance >20%. Infineon specifies this module for single-arm or dual-arm use within one housing; higher current should be addressed via higher-rated modules like DD300N16KHP instead of paralleling.
What is the creepage distance and why does it matter for this module?
The creepage distance is 17 mm, measured across the insulated AlN baseplate surface between high-voltage terminals. This value satisfies IEC 61800-5-1 requirements for Pollution Degree 2 environments and ensures safe operation at 1600 V reverse voltage without surface tracking, especially in humid or dusty industrial enclosures where contamination could otherwise reduce insulation integrity.
