Product details
Overview
DD104N12KHPSA1 from Semikron is a press-pack dual-diode rectifier module rated for 1200 V repetitive peak reverse voltage (VRRM), 104 A average on-state current (IFAVM) 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 DD104N12KHPSA1 datasheet, DD104N12KHPSA1 pinout, DD104N12KHPSA1 application, or DD104N12KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.195 °C/W per module), forward voltage drop (1.4 V max at 300 A, Tvj max), surge current capability (2.9 kA, 10 ms), and pressure-contact Si pellet construction with AlN isolation.
Technical Context
This dual-diode module implements a single-phase, center-tapped or full-bridge rectification topology using silicon die with pressure-contact metallization and aluminum nitride (AlN) internal insulation. It supports both natural and forced-air cooling via heatsink interface with defined mounting torque (4 Nm for M1/M2 terminals).
Thermal performance is characterized by transient junction-to-case impedance (ZthJC) with analytical R–τ network parameters, and junction-to-ambient behavior depends on heatsink type (e.g., KM14) and cooling mode-enabling precise thermal derating for B2/B6 topologies across ambient temperatures from –40°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - Maximum repetitive reverse blocking voltage per diode arm; defines usable DC bus voltage in B6 rectifiers up to ~1000 V DC. |
| IFAVM | 104 A at TC = 100°C - Continuous average forward current per arm; sets base-load rating under standard heatsink conditions. |
| IFRMSM | 160 A - RMS current handling capacity; determines I²t-based fuse coordination and thermal stress under non-sinusoidal loads. |
| vF max | 1.4 V at iF = 300 A, Tvj max - Peak forward voltage drop; directly impacts conduction loss (P = I × vF) and thermal design margin. |
| RthJC | 0.195 °C/W per module - Junction-to-case thermal resistance (180° sine); enables calculation of maximum allowable case temperature for given power dissipation. |
| IFS M | 2900 A, 10 ms - Non-repetitive surge current rating; defines short-circuit withstand capability during line faults or inrush events. |
| Qr | Not specified in provided data - Recovered charge not listed; softness factor and reverse recovery behavior require separate characterization or test report. |
Pinout & Package
DD104N12KHPSA1 is housed in a press-pack module with two isolated diode arms sharing a common cathode configuration (BIP AC type). Mechanical interface uses M1 (case mounting) and M2 (electrical terminal) screws; weight is 160 g. Creepage distance is 15 mm; internal isolation uses AlN ceramic.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| K1 / K2 | Common Cathode Terminals | Electrically connected internally; serve as output DC negative node in B2/B6 bridges; require low-inductance, high-current busbar connection. |
| A1 / A2 | Anode Terminals | Independent AC input nodes per diode arm; support phase-split or split-winding transformer connections in dual-arm operation. |
| Case | Thermal & Electrical Reference | Electrically isolated via AlN; serves as mechanical mounting surface and primary heat transfer path to heatsink (RthCH ≤ 0.05 °C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact Si pellet | Enables high-current density and low contact resistance without solder fatigue; suitable for >10⁶ thermal cycles in industrial drives. |
| AlN internal isolation | Provides 3.0 kV RMS insulation (1 sec, 50 Hz) and stable dielectric performance up to 150°C junction temperature. |
| Dual-arm modular layout | Allows flexible use in B2 (single-phase) or B6 (three-phase) rectifier topologies without external paralleling components. |
| Defined RthCH interface | 0.05 °C/W max case-to-heatsink resistance ensures predictable thermal coupling when mounted with 4 Nm torque on flat, greased surfaces. |

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 |
|---|---|---|---|
| DD104N16KHPSA1 | Higher VRRM (1600 V); identical package, thermal, and current ratings. | Supports higher DC bus voltages (e.g., 1200 V DC systems); requires matching transformer and snubber design. | Select when system DC link exceeds 1000 V or long-term voltage margin is critical. |
| DD98N12KHPSA1 | Lower IFAVM (98 A); same VRRM, package, and thermal resistance. | Suitable for lower continuous load profiles; reduced conduction loss at partial load due to tighter vF distribution. | Choose where average load stays below 90 A and cost optimization is prioritized over headroom. |
Compared with DD104N12KHPSA1, DD104N16KHPSA1 trades no current penalty for higher voltage robustness, while DD98N12KHPSA1 reduces thermal margin but improves partial-load efficiency-making each optimal for distinct DC bus voltage and loading profiles.

FAQ
What is the mounting torque specification for DD104N12KHPSA1 terminals?
The mechanical mounting torque (M1) is 4 Nm ±15%, and the electrical terminal torque (M2) is also 4 Nm ±10%. These values ensure reliable pressure contact between the Si pellet and copper baseplate while maintaining AlN insulation integrity and minimizing thermal interface resistance.
Does DD104N12KHPSA1 support three-phase six-pulse rectification?
Yes-DD104N12KHPSA1 is configured as a dual-diode module with independent anodes (A1, A2) and common cathodes (K1, K2), enabling direct implementation in B6 (six-pulse) rectifier circuits when paired with appropriate transformer winding and heatsinking per arm.
What is the maximum allowable junction temperature and how is it enforced?
The maximum junction temperature (Tvj max) is 150°C. This limit is enforced through thermal design using the specified RthJC (0.195 °C/W per module) and RthCH (0.05 °C/W), combined with measured case temperature and calculated power loss (P = IF × vF + I² × rT) under actual operating conduction angles.
Is reverse recovery charge (Qr) specified for this module?
No-Qr is not listed in the provided datasheet excerpt. The document includes Qr vs. –di/dt curves only for iFM = 500 A and other test currents, but no tabulated Qr value at rated conditions. Designers must extract Qr from graphical data or consult Semikron's application note SN-17-001 for standardized test conditions.
