Product details
Overview
DD170N36KHPSA1 from Infineon Technologies is a press-pack rectifier diode module with dual-arm configuration, rated for 3600 V repetitive peak reverse voltage (VRRM), 170 A average forward current at TC = 100 °C (IFAVM), and 5300 A non-repetitive surge current (IFSM). It employs pressure-contact silicon die technology and features electrically insulated AlN baseplate for high-reliability industrial drive rectification.
For engineers reviewing the DD170N36KHPSA1 datasheet, DD170N36KHPSA1 pinout, DD170N36KHPSA1 application, or DD170N36KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.193 K/W per arm), threshold voltage (0.9 V), slope resistance (1.35 mΩ), and isolation test voltage (3.6 kV RMS/1 sec).
Technical Context
This dual-arm rectifier module uses pressure-contact construction to eliminate wire bonds and solder layers, enabling robust thermal cycling performance and stable forward voltage characteristics under high-current DC and phase-controlled AC operation. Its 150 °C maximum junction temperature and 0.193 K/W RthJC (per arm, DC) support high-power density in forced-air or liquid-cooled heatsink assemblies.
The module integrates basic insulation per IEC 61140 Class 1, with 15 mm creepage distance and 3.6 kV RMS/1 sec isolation test rating. Thermal transient impedance data (ZthJC analytical model) and derating curves for Θ = 30°–180° conduction angles are provided for accurate loss and temperature prediction in six-pulse (B6) and two-pulse (B2) bridge topologies.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum allowable case temperature (TC) is not fixed independently but is determined by the relationship between IFAVM and TC. At TC = 100 °C, the module supports 170 A average forward current. Derating curves show TC can reach 120 °C at ~140 A and 140 °C at ~90 A, with absolute upper limit constrained by Tvj max = 150 °C and thermal interface quality.
Is DD170N36KHPSA1 suitable for use in a single-phase full-wave bridge?
Yes - the dual-arm configuration supports single-phase full-wave (B2) rectification. Each arm functions as one leg of the bridge. External wiring connects A1/K1 and A2/K2 to AC inputs and DC outputs respectively. Mounting must ensure symmetrical thermal loading across both arms to prevent imbalance.
Does this module require external snubbers in typical industrial rectifier applications?
No external snubbers are required for standard line-commutated rectifier operation (e.g., B2/B6 bridges with inductive loads). The module's 3700 V VRSM rating and soft reverse recovery behavior (not explicitly specified but inherent to press-pack Si diodes) provide sufficient margin against commutation overshoot in most industrial mains-fed applications.
How does the pressure-contact construction affect replacement or rework procedures?
Pressure-contact modules like DD170N36KHPSA1 are not field-repairable. Replacement requires full module swap using calibrated torque (6 Nm for M2 terminals) and verified heatsink flatness (<0.05 mm deviation). Reuse of removed modules is not recommended due to irreversible contact deformation and potential AlN surface damage affecting RthCH and isolation integrity.
