Product details
Overview
ND171N16KHPSA2 from Netz is a high-power press-pack rectifier diode module with dual-arm configuration, rated for 171 A average on-state current (IFAVM) at TC = 100°C, 1600 V repetitive peak reverse voltage (VRRM), and 6.6 kA non-repetitive surge current (IFSM) at Tvj = 25°C. It employs silicon pellets with AlN internal insulation and is designed for industrial AC/DC conversion in medium-voltage drive systems.
For engineers reviewing the ND171N16KHPSA2 datasheet, ND171N16KHPSA2 pinout, ND171N16KHPSA2 application, or ND171N16KHPSA2 equivalent, key selection criteria include junction-to-case thermal resistance (0.130 °C/W per module), forward voltage drop (1.26 V max at 500 A), and pressure-contact mechanical mounting requirements (6 Nm torque).
Technical Context
This dual-arm rectifier module operates in full-wave bridge configurations (B2/B6), supporting both natural and forced-air cooling via heatsink KM17. Its thermal design relies on transient thermal impedance modeling (ZthJC analytical elements provided for Θ = 180° sin), enabling accurate loss and temperature prediction under pulsed loads.
The device uses silicon die with pressure-contact metallization and aluminum nitride (AlN) internal isolation, delivering low slope resistance (0.8 mΩ) and threshold voltage (0.75 V) to minimize conduction losses in high-current DC-link applications 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 usable DC-link voltage headroom in 1100–1200 VAC input systems |
| IFAVM | 171 A - continuous average forward current per arm at TC = 100°C, setting steady-state power handling in rectifier bridges |
| IFRMSM | 270 A - RMS on-state current rating, used for thermal sizing of heatsinks and busbar conductors under sinusoidal load |
| vF max | 1.26 V - maximum forward voltage at 500 A and Tvj = 150°C, directly determining conduction loss (P = I × vF) at peak load |
| RthJC | 0.130 °C/W - maximum junction-to-case thermal resistance per module, critical for calculating case temperature rise under given power dissipation |
| IFS M | 6600 A - non-repetitive surge current capability at tP = 10 ms, enabling short-circuit ride-through in motor drive inverters |
| Qr | Not specified in provided data - recovered charge not listed; softness factor and reverse recovery behavior require external characterization |
Pinout & Package
ND171N16KHPSA2 is housed in a press-pack module with two isolated power arms (anode/cathode per arm), no leaded package. Electrical terminals are M2 screw connections (6 Nm ±10% torque); mechanical mounting uses M1 screws (6 Nm ±15%). Internal Si pellets use AlN ceramic isolation. No discrete pin numbering applies - terminals are functionally labeled: A1, K1 (Arm 1), A2, K2 (Arm 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Arm 1 | High-side connection point for first diode arm in B6 bridge; carries full phase current during conduction interval |
| K1 | Cathode of Arm 1 | Low-side return path for Arm 1; electrically isolated from A2/K2 by AlN substrate |
| A2 | Anode of Arm 2 | Second independent diode arm for complementary phase conduction; enables dual-arm parallel or interleaved operation |
| K2 | Cathode of Arm 2 | Isolated output node for Arm 2; allows separate thermal monitoring or current sensing per arm |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact Si die | Enables high-current density (≥171 A/arm) without wire bonds, improving reliability under thermal cycling |
| AlN internal isolation | Provides 2.5 kV RMS insulation between arms, supporting safe operation in grounded-neutral or floating DC-link topologies |
| Low rT (0.8 mΩ) | Reduces forward conduction loss by ~15% vs. comparable modules with higher slope resistance, lowering heatsink requirements |
| Rated Tvj max = 150°C | Allows operation in high-ambient environments (e.g., enclosed drives) without derating below 100°C case temperature |
| Mechanical torque spec | 6 Nm terminal torque ensures stable contact resistance over lifetime, preventing hot-spot formation at high RMS currents |

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 |
|---|---|---|---|
| DD171N16K | Same electrical ratings (VRRM, IFAVM, IFSM), but single-arm configuration and different mechanical footprint (DD-series housing) | Lacks dual-arm isolation; requires two units for B6 bridge vs. one ND171N16KHPSA2 module | Select when space permits discrete mounting or when AlN isolation between arms is not required |
| SKKD162/16 | Lower VRRM (1600 V same), but lower IFAVM (162 A), higher RthJC (0.15 °C/W), and different torque specs (M3 terminals) | Designed for standard stud-mounting; lacks integrated dual-arm layout and creepage optimization | Prefer for legacy designs using stud-base heatsinks or where M3 mechanical interface is standardized |
Compared with DD171N16K and SKKD162/16, ND171N16KHPSA2 offers integrated dual-arm topology with tighter thermal resistance (0.130 °C/W) and optimized creepage (15 mm), reducing system-level component count and improving power density in new B6 rectifier designs.

FAQ
What is the recommended heatsink mounting procedure for ND171N16KHPSA2?
Mount the module onto a flat, clean heatsink surface using M1 screws at 6 Nm ±15% torque. Apply uniform pressure across the module baseplate to ensure full contact with the AlN isolation layer. Use thermal interface material compatible with 150°C operation and verify flatness tolerance ≤0.05 mm over the mounting area to prevent localized hot spots.
Does ND171N16KHPSA2 support paralleling of arms for higher current capacity?
No - the two arms are electrically isolated but not internally paralleled. Each arm (A1/K1 and A2/K2) must be used independently in circuit topologies such as B6 bridges. Paralleling arms externally requires matched thermal paths and current-sharing inductors to avoid imbalance.
What is the insulation test voltage rating and duration for ND171N16KHPSA2?
The module is rated for 2.5 kV RMS insulation test voltage at 50 Hz for 1 minute between isolated arms (A1–A2, K1–K2) and between each arm and baseplate, per the datasheet's VISOL specification for the "-K" variant suffix in the ND171N series.
Can ND171N16KHPSA2 be used in phase-controlled rectifier applications?
No - it is an uncontrolled rectifier diode module with no gate control. It is intended only for freewheeling or uncontrolled rectification. For phase control, a thyristor-based module (e.g., Netz's NT-series) with gate triggering capability is required.
