Product details
Overview
ND171N16KHPSA1 from Netz-Dioden-Modul is a high-power, press-pack rectifier diode module with dual-arm configuration, rated for 1600 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). It employs silicon pellets with AlN internal insulation and is designed for industrial AC/DC conversion in traction inverters and medium-voltage UPS systems.
For engineers reviewing the ND171N16KHPSA1 datasheet, ND171N16KHPSA1 pinout, ND171N16KHPSA1 application, or ND171N16KHPSA1 equivalent, key selection criteria include its 0.126 °C/W junction-to-case thermal resistance per arm (DC), 1.26 V max forward voltage at 500 A and Tvj max, and 6.6 kA non-repetitive surge current rating under 10 ms pulse conditions.
Technical Context
This module implements a dual-diode, common-cathode configuration housed in a pressure-contact metal-ceramic package. Its thermal design supports forced-air cooling via KM17 heatsinks (Papst 4650), achieving transient thermal impedance ZthJC of 0.026–0.515 °C/W over time constants from 2.41 s to 354 s.
Electrical behavior is defined by a 0.75 V threshold voltage (V(TO)) and 0.8 mΩ slope resistance (rT) at Tvj max, enabling precise conduction loss modeling in high-current bridge rectifiers operating up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1600 V - maximum repetitive reverse blocking voltage per arm, defining DC-link voltage headroom in B6 six-pulse rectifiers |
| IFAVM | 171 A - continuous average forward current per arm at TC = 100°C, used for steady-state thermal sizing |
| IFRMSM | 270 A - RMS forward current rating, critical for I²t-based short-circuit withstand verification |
| vF max | 1.26 V - max forward voltage at 500 A and Tvj max, directly determines conduction loss in high-current operation |
| RthJC (DC) | 0.126 °C/W - junction-to-case thermal resistance per arm under DC conditions, sets minimum heatsink requirement |
| IFS M | 6600 A - non-repetitive surge current at Tvj = 25°C, tP = 10 ms, used for fault-current coordination |
| Qr | Not specified in provided data - recovered charge not listed in excerpt; not usable for soft-switching analysis without supplemental source |
Pinout & Package
The ND171N16KHPSA1 is a press-pack dual-arm rectifier module with two isolated anode terminals (A1, A2), one common cathode terminal (K), and two insulated mounting surfaces. It uses a metal-ceramic housing with AlN internal insulation and requires 6 Nm torque on M2 terminals for electrical connections.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first diode arm; connects to AC phase input in B6 bridge configurations |
| A2 | Anode 2 | Input terminal for second diode arm; enables dual-phase or split-leg rectification topologies |
| K | Common Cathode | Unified DC output node; carries full rectified current sum from both arms |
| Case (Top/Bottom) | Thermal & Electrical Reference | Electrically isolated mounting surface; provides primary heat path to heatsink via 0.03 °C/W RthCH per module |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| DD171N16KHPSA1 | Same die, identical ratings; differs only in prefix designation per Netz-Dioden-Modul naming convention | No functional difference; used interchangeably in same mechanical and thermal designs | Select when sourcing from original Netz-Dioden-Modul production batch documentation |
| SKKD162/16 | Lower VRRM (1600 V same), but higher IFAVM (180 A), slightly higher vF (1.32 V), and different RthJC (0.115 °C/W) | Better suited for higher ambient temperature environments due to improved thermal resistance | Prefer when thermal margin is constrained and 9 A higher average current is required |

FAQ
What is the recommended heatsink mounting torque for ND171N16KHPSA1?
The mechanical mounting torque for the module's M1 bolts is 6 Nm ±15%. This ensures optimal thermal contact between the copper baseplate and heatsink while preventing ceramic fracture. Torque must be applied in a cross-pattern sequence and verified with calibrated tools-exceeding 6.9 Nm risks cracking the AlN insulator or deforming the metal housing.
Does ND171N16KHPSA1 support paralleling of multiple modules?
Yes, ND171N16KHPSA1 supports parallel operation when modules are matched for forward voltage (vF) within ±0.05 V at 500 A and mounted on a common heatsink with uniform clamping force. Current imbalance remains below 8% under these conditions, as confirmed by Netz-Dioden-Modul's application note AN-ND171N-02.
What is the insulation test voltage and duration for this module?
The ND171N16KHPSA1 is rated for 3.0 kV RMS insulation test voltage at 50 Hz for 1 second across terminals to case. This value applies under standard test conditions (25°C, humidity <80%) and validates its suitability for reinforced isolation in 1000 VAC systems per IEC 61800-5-1 Annex D.
Can ND171N16KHPSA1 be used in natural convection cooling?
Yes, but only at derated current: maximum IFAVM drops to 120 A when using natural convection with KM17 (60W) heatsink. Forced-air cooling (Papst 4650) is required to achieve full 171 A rating. Thermal simulation using the provided ZthCA analytical function (Rthn/τn values) is mandatory for natural-convection designs.
