Product details
Overview
DD171N12KKHPSA1 from Semikron is a press-pack dual-diode rectifier module with 1200 V repetitive peak reverse voltage (VRRM), 171 A average on-state current (IFAVM) at TC = 100°C, and 270 A RMS on-state current (IFRMSM), designed for high-power industrial AC/DC conversion in six-pulse bridge configurations.
For engineers reviewing the DD171N12KKHPSA1 datasheet, DD171N12KKHPSA1 pinout, DD171N12KKHPSA1 application, or DD171N12KKHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.130 °C/W per module), surge current rating (6.6 kA @ 10 ms), and pressure-contact Si pellet construction for high-reliability power conversion systems.
Technical Context
This dual-diode module implements a single-phase, two-arm configuration with isolated AlN ceramic substrate and symmetrical thermal paths. Each arm supports 171 A DC conduction at 100°C case temperature and exhibits 1.26 V maximum forward voltage at 500 A and Tvj = 150°C.
Thermal performance is defined by transient junction-to-case impedance (ZthJC) with analytical R-τ elements including R1 = 0.0094 °C/W, τ1 = 0.0014 s, and steady-state RthJC = 0.130 °C/W per module under 180° sine conduction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-power rectifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SKD171/12 | Same VRRM (1200 V), lower IFAVM (150 A), higher RthJC (0.155 °C/W) | Requires larger heatsink area for same 171 A load; suitable where space permits conservative derating | Select when legacy SKiiP® compatibility or standardized footprint is required over peak current density |
| DD171N12KHPSA1 | Same package, identical pinout, but rated for 1600 V VRRM and 5.6 kA IFSM (Tvj max) | Higher voltage margin enables use in 1380 V AC systems; reduced surge headroom at elevated junction temperature | Select when system-level overvoltage transients exceed 1200 V but 171 A DC rating must be preserved |
Compared with SKD171/12, DD171N12KKHPSA1 delivers 14% higher continuous current density and 16% lower thermal resistance; versus DD171N12KHPSA1, it trades 400 V blocking margin for 1 kA higher surge rating at room temperature-critical for short-circuit robustness in drive inverters.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum allowable case temperature is 100°C for rated 171 A average on-state current (IFAVM). Operation above this temperature requires linear derating per the IFAVM vs. TC curve in the datasheet, with absolute maximum junction temperature limited to 150°C.
Does DD171N12KKHPSA1 support forced-air or liquid cooling?
Yes-it is qualified for both natural convection and forced-air cooling, with documented ZthCA models for KM17 heatsinks using Papst 4650 fans. Liquid-cooled mounting is supported via standard press-pack interface but requires custom cold-plate design and torque validation.
Is the module RoHS-compliant and halogen-free?
Yes-DD171N12KKHPSA1 complies with EU RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The AlN substrate, copper terminals, and silicone grease meet material declarations in Semikron's compliance documentation dated 2022.
Can this module replace older DD171N12K in existing designs?
Yes-DD171N12KKHPSA1 shares identical mechanical dimensions, terminal layout, and mounting torque specifications with DD171N12K. Electrical parameters are identical except for minor improvements in RthJC and I²t rating, enabling direct drop-in use without redesign.
