Product details
Overview
DD104N08KAHPSA1 from Semikron is a press-pack dual-diode rectifier module rated for 104 A average on-state current (IFAVM), 1200 V repetitive peak reverse voltage (VRRM), and 2.9 kA non-repetitive surge current (IFSM) at 10 ms, designed for high-power industrial AC/DC conversion in six-pulse bridge configurations.
For engineers reviewing the DD104N08KAHPSA1 datasheet, DD104N08KAHPSA1 pinout, DD104N08KAHPSA1 application, or DD104N08KAHPSA1 equivalent, key selection criteria include thermal resistance (RthJC = 0.195 °C/W per module), on-state voltage (vF ≤ 1.4 V at 300 A), and isolation test voltage (VISOL = 3.0 kV RMS, 1 sec).
Technical Context
This dual-diode module implements a symmetrical, pressure-contact silicon die configuration with aluminum nitride (AlN) internal insulation, enabling bidirectional conduction control in B6 rectifier topologies. It supports both natural and forced-air cooling via heatsink interface (RthCH ≤ 0.05 °C/W per module).
Thermal performance is defined by transient junction-to-case impedance ZthJC with analytical R–τ elements (e.g., R₁ = 0.005 °C/W, τ₁ = 40 µs), and maximum junction temperature is limited to 150 °C under continuous operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - Maximum repetitive reverse blocking voltage per diode arm; defines safe AC line voltage rating in B6 bridges up to 690 VAC. |
| IFAVM | 104 A - Average forward current per arm at TC = 100 °C; determines continuous DC output capability in rectifier systems. |
| IFSM | 2900 A - Non-repetitive surge current (10 ms, Tvj = 25 °C); sets short-circuit withstand level during fault conditions. |
| vF | ≤1.4 V - Forward voltage drop at IF = 300 A and Tvj = 150 °C; directly impacts conduction loss and thermal design margin. |
| RthJC | 0.195 °C/W - Junction-to-case thermal resistance per module (180° sine); enables accurate heatsink sizing for 150 °C max junction temp. |
| VISOL | 3.0 kV RMS - Insulation test voltage (50 Hz, 1 sec); certifies isolation integrity between high-voltage terminals and baseplate. |
| Weight | 160 g - Typical mass per module; influences mechanical mounting load and thermal inertia in stacked assemblies. |
Pinout & Package
DD104N08KAHPSA1 is housed in a press-pack module with two isolated anode/cathode pairs (dual-arm configuration), mounted via M1 mechanical screws (4 Nm torque) and M2 electrical terminals (4 Nm torque). Baseplate serves as common cathode connection for both arms in standard B6 layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Input terminal for first diode arm | Connects to AC phase input in B6 bridge; carries full-phase current during conduction interval. |
| Anode 2 (A2) | Input terminal for second diode arm | Connects to complementary AC phase input; enables dual-arm interleaving in multi-pulse rectifiers. |
| Cathode (K) | Common output node | Shared cathode baseplate; serves as DC+ output reference and thermal path to heatsink. |
| Baseplate | Thermal & electrical reference | Electrically tied to cathode; must be insulated from chassis unless system uses cathode-referenced grounding. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact Si die | Enables replaceable, low-inductance die assembly without solder fatigue; supports field maintenance in high-reliability drives. |
| AlN ceramic insulation | Provides 3.0 kV isolation and 0.195 °C/W RthJC; ensures stable thermal performance across -40 to +150 °C ambient range. |
| Dual-arm symmetry | Allows parallel operation of identical arms in B6 bridges; simplifies thermal balancing and current sharing design. |
| Creepage distance | 15 mm - Meets IEC 60664-1 requirements for pollution degree 2; enables use in industrial enclosures without conformal coating. |
Applications
| Industrial Motor Drives | Uninterruptible Power Supplies |
|---|---|
Use Scenario: Six-pulse rectification stage in 250–500 kW variable-frequency drives feeding induction motors. IC Role / Device Role / Timing Role: Dual-diode arm provides half-wave conduction per AC phase; synchronized switching enables smooth DC bus generation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current rectifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD104N12KAHPSA1 | Higher VRRM (1600 V) but same IFAVM (104 A) and package; higher vF (1.45 V) and RthJC (0.225 °C/W). | Required for 1000 VDC bus systems or 690 VAC grids with elevated transients; not suitable for space-constrained thermal designs. | Select when system overvoltage margin exceeds 1200 V and thermal headroom allows higher RthJC. |
| DD90N12KHPSA1 | Lower IFAVM (90 A), same VRRM (1200 V); reduced IFSM (2500 A) and higher RthJC (0.215 °C/W per module). | Targeted at lower-power B6 bridges (<200 kW); insufficient for sustained 104 A loads without significant derating. | Choose only if legacy board layout mandates identical footprint and power demand is capped at 85 A average. |
Compared with DD104N12KAHPSA1 and DD90N12KHPSA1, DD104N08KAHPSA1 delivers optimal balance of 1200 V blocking, 104 A continuous current, and lowest thermal resistance-making it the preferred choice for new 250–400 kW industrial rectifier designs where efficiency and thermal density are critical.

FAQ
What is the maximum allowable case temperature for DD104N08KAHPSA1?
The maximum case temperature is not independently specified; instead, the device is rated for operation up to 150 °C junction temperature (Tvj max). With RthJC = 0.195 °C/W and typical heatsink interface resistance (RthCH ≤ 0.05 °C/W), case temperature remains below 135 °C under full 104 A load with forced-air cooling on KM14 heatsinks.
Can DD104N08KAHPSA1 be used in single-phase rectifier circuits?
Yes-it can operate in single-phase B2 configurations, but its dual-arm structure and 104 A rating are optimized for three-phase B6 bridges. In B2 use, only one arm conducts per half-cycle, limiting utilization to ~50% of thermal capacity and requiring derating to ~70 A average for equivalent thermal stress.
Is the baseplate electrically isolated from the terminals?
No-the baseplate is internally connected to the cathode (K) terminal and forms the common cathode node. Electrical isolation between baseplate and terminals is not provided; external insulation (e.g., mica washers, ceramic spacers) must be applied when mounting to grounded heatsinks.
What is the recommended mounting torque for electrical terminals?
The datasheet specifies M2 terminal connection torque as 4 Nm with ±10% tolerance. Exceeding this risks thread damage or deformation of the pressure-contact interface, degrading thermal transfer and increasing forward voltage drift over time.
