Product details
Overview
ND104N16KHPSA1 from Semikron is a dual-arm press-pack rectifier diode module rated for 1600 V repetitive peak reverse voltage (VRRM), 104 A average on-state current (IFAVM) per arm at TC = 100°C, and 160 A RMS on-state current (IFRMSM), designed for high-power industrial AC/DC conversion in six-pulse bridge (B6) and two-pulse bridge (B2) configurations.
For engineers reviewing the ND104N16KHPSA1 datasheet, ND104N16KHPSA1 pinout, ND104N16KHPSA1 application, or ND104N16KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.185 °C/W per arm, DC), forward voltage drop (1.4 V max at 300 A, Tvj = Tmax), surge current rating (2.9 kA, 10 ms), and pressure-contact Si pellet construction with AlN isolation.
Technical Context
This dual-arm diode module implements a symmetrical, isolated press-pack structure with silicon pellets mounted under mechanical pressure and insulated by aluminum nitride (AlN) substrates. Each arm supports independent conduction with identical electrical and thermal ratings.
It operates across -40°C to +150°C case temperature range and delivers stable performance under sinusoidal (180°) and rectangular (60°–180°) conduction angles, with transient thermal impedance characterized analytically for both natural and forced cooling conditions using KM14 heatsinks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1600 V - Maximum repetitive reverse blocking voltage per arm; defines usable DC bus voltage in B6 rectifiers up to ~1100 V line-to-line. |
| IFAVM | 104 A - Average forward current per arm at TC = 100°C; sets continuous power handling in thermally managed industrial drives. |
| IFRMSM | 160 A - RMS on-state current rating; determines I²t-based fuse coordination and thermal stress under non-sinusoidal loads. |
| vF max | 1.4 V - Maximum forward voltage at 300 A and max junction temperature; directly impacts conduction loss (P = I × vF) in high-current operation. |
| RthJC | 0.185 °C/W - Junction-to-case thermal resistance per arm (DC); enables precise junction temperature estimation using measured case temperature. |
| IFS M | 2900 A - Non-repetitive surge current (10 ms, Tvj = 25°C); supports short-circuit withstand in motor drive DC links. |
| Qr | Not specified - Recovered charge not provided in datasheet; softness factor and reverse recovery behavior require external characterization for EMI-sensitive designs. |
Pinout & Package
ND104N16KHPSA1 uses a dual-arm press-pack module package with two isolated anode-cathode arms housed in a single metal baseplate. Electrical connections are made via M2 terminal screws (4 Nm torque, ±10% tolerance) for each arm's anode and cathode, and the baseplate serves as the common thermal interface. No plastic encapsulation or leadframe; relies on mechanical clamping for die contact.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Arm 1 anode | High-side connection point for first diode arm in B2/B6 bridge; carries full phase current during positive half-cycle. |
| Cathode 1 (K1) | Arm 1 cathode | Low-side return for Arm 1; electrically isolated from Arm 2 and baseplate except via heatsink mounting surface. |
| Anode 2 (A2) | Arm 2 anode | Second arm anode; used for complementary phase conduction in B6 configuration or parallel current sharing. |
| Cathode 2 (K2) | Arm 2 cathode | Isolated low-side node for Arm 2; enables independent gate/control routing in multi-arm topologies. |
| Baseplate | Thermal interface / mechanical ground | Electrically isolated via AlN substrate; must be mounted to heatsink with uniform pressure (0.05 °C/W RthCH max per arm) to maintain thermal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact Si pellet | Enables high-current density without wire bonds; eliminates bond-wire failure modes under thermal cycling. |
| AlN internal isolation | Provides 2.5 kV RMS insulation (1 min) and superior thermal conductivity vs. alumina, reducing RthJC by ~15%. |
| Dual-arm symmetry | Allows flexible use in B2 (single-phase) or B6 (three-phase) rectification without derating; arms share identical VRRM/IFAVM. |
| DC and AC-rated RthJC | 0.185 °C/W (DC) and 0.370 °C/W (AC, 180° sin) enable accurate thermal modeling for both steady-state and pulsed operation. |
| M2 terminal torque spec | 4 Nm (±10%) ensures repeatable contact resistance and prevents cold welding or loosening under vibration (50 m/s²). |
Applications
| Industrial Motor Drives | Uninterruptible Power Supplies |
|---|---|
Use Scenario: Three-phase AC input rectification in 100–200 kW variable-frequency drives with active front-end or diode-based DC link.

IC Role / Device Role / Timing Role: Primary rectifier in double-conversion topology; handles continuous load current plus battery-charge surges. Use Value: Pressure-contact construction eliminates bond-wire fatigue; 150°C max junction temperature allows operation in sealed, fanless enclosures. |
| Welding Power Supplies | Renewable Energy Inverters |
Use Scenario: Secondary-side rectification in medium-frequency transformer-isolated IGBT-based welding inverters. IC Role / Device Role / Timing Role: Output-stage diode module converting high-frequency AC (2–20 kHz) to DC weld current; operates with 60°–120° conduction angle. Use Value: Low 2.1 mΩ slope resistance (rT) minimizes dynamic losses during rapid current transitions; 2.9 kA IFSM withstands arc ignition transients. | Use Scenario: Grid-tied solar/wind inverter front-end rectification in hybrid microgrid applications with bidirectional power flow capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, high-current rectifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD104N16KHPSA1 | Same die, identical ratings; differs only in part numbering convention (DD prefix denotes single-arm variant). | Single-arm use requires paralleling two units for B6; increases footprint and thermal interface count. | Select when modular layout or separate arm control is required. |
| SKD 104/16 | 1600 V VRRM, 104 A IFAVM, but uses solder-bonded die and ceramic DBC substrate; RthJC = 0.21 °C/W (higher than ND104N's 0.185 °C/W). | Better suited for PCB-mount applications; less tolerant of thermal cycling than press-pack construction. | Select when automated assembly or lower clamping force is mandatory. |
Compared with DD104N16KHPSA1 and SKD 104/16, ND104N16KHPSA1 offers lowest RthJC and highest surge robustness due to pressure-contact architecture, making it optimal for high-reliability, high-thermal-stress industrial rectification where maintenance access is limited.

FAQ
What is the maximum allowable case temperature for continuous operation?
The ND104N16KHPSA1 has a maximum case operating temperature of +150°C, aligned with its 150°C maximum junction temperature rating. At TC = 100°C, it delivers its full 104 A average forward current per arm. Derating curves in the datasheet define linear reduction to zero current at TC = 150°C for DC operation.
Does this module require thermal interface material between baseplate and heatsink?
Yes - a thermally conductive, electrically insulating interface material (e.g., silicone grease or phase-change pad) is mandatory to achieve the specified 0.05 °C/W RthCH (case-to-heatsink) value. Dry mounting or improper paste application increases thermal resistance and risks premature thermal runaway.
Can ND104N16KHPSA1 be used in a single-phase full-wave bridge?
Yes - the dual-arm configuration supports B2 (two-pulse) single-phase rectification. Each arm functions as one leg of the bridge; A1/K1 and A2/K2 connect to opposite AC terminals and common DC output nodes. Full 104 A IFAVM rating applies per arm under balanced loading.
What is the insulation test voltage and duration for safety compliance?
The ND104N16KHPSA1 is rated for 2.5 kV RMS insulation test voltage at 50 Hz for 1 minute between terminals and baseplate. This meets IEC 60747-1 and UL 1557 requirements for reinforced insulation in industrial equipment operating up to 1000 VDC systems.
