Product details
Overview
DD241S12KHPSA1 from eupec (now Infineon Technologies) is a 1200 V, 240 A average forward current, press-pack dual-diode module with common-cathode configuration, rated for 9300 A non-repetitive surge current and 0.15 °C/W thermal resistance per arm, used in high-power industrial rectification and traction inverters.
For engineers reviewing the DD241S12KHPSA1 datasheet, DD241S12KHPSA1 pinout, DD241S12KHPSA1 application, or DD241S12KHPSA1 equivalent, key selection criteria include repetitive peak reverse voltage (1200 V), RMS forward current (410 A), junction-to-case thermal resistance (0.15 °C/W per arm), surge current capability (9300 A), and pressure-contact Si-pellet construction for forced-cooled systems.
Technical Context
This dual-diode module uses silicon pellets with ceramic (AlN) internal insulation and mechanical pressure contact-no solder bonds-enabling high-reliability operation under extreme thermal cycling. Its 180° electrical conduction angle rating supports full-wave rectification in line-commutated converters.
The device features a threshold voltage of 1.1 V and slope resistance of 0.5 mΩ, yielding low conduction losses at rated current; its recovered charge (Qr = 250 µAs at −diF/dt = 100 A/µs) and peak reverse recovery current (135 A) are optimized for controlled commutation in medium-frequency DC-link applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - maximum repetitive reverse blocking voltage per diode arm |
| IFAVM | 240 A at TC = 100°C - continuous DC forward current per arm with heatsink cooling |
| IFRMSM | 410 A - RMS forward current rating defining thermal design margin under AC waveform stress |
| IFSM | 9300 A (tp = 10 ms, Tj ≤ 25°C) - short-circuit robustness for fault ride-through in converter legs |
| RthJC | 0.15 °C/W per arm - junction-to-case thermal resistance enabling precise heatsink sizing for forced-air or liquid cooling |
| VF | 1.55 V max at TJ = 150°C, IF = 800 A - conduction loss baseline for efficiency calculation at peak load |
| Qr | 250 µAs at −diF/dt = 100 A/µs - recovered charge determining snubber sizing and commutation losses |
Pinout & Package
DD241S12KHPSA1 is a press-pack dual-diode module with common-cathode topology housed in a metal-ceramic package (AlN isolation) and secured via M16 mounting bolts. Electrical terminals are pressure-contacted copper posts: two anode inputs (pins 1 & 2), one shared cathode output (pin 3), and two isolated case grounds (pins 4 & 5).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Post) | Input terminal for first diode arm | Carries up to 410 A RMS; requires ≥16 Nm torque for reliable pressure contact |
| Anode 2 (Post) | Input terminal for second diode arm | Enables parallel-phase or split-leg connection in 12-pulse rectifiers |
| Cathode (Common Post) | Shared output node for both diodes | Single low-inductance return path; critical for minimizing commutation voltage spikes |
| Case Ground 1 | Thermal and electrical reference point | Provides low-impedance path to heatsink; must be bolted with 12 Nm torque (±5%/−10%) |
| Case Ground 2 | Redundant thermal/electrical reference | Ensures uniform pressure distribution and EMI control in high-dV/dt environments |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact Si pellet construction | Eliminates solder fatigue failure mode; enables >100,000 thermal cycles in traction duty |
| AlN (aluminum nitride) internal insulation | 3 kV RMS isolation withstand with 17 mm creepage distance for 1500 V DC systems |
| Common-cathode dual-arm topology | Reduces external busbar inductance by 40% vs. discrete diode pairs in 6-pulse rectifiers |
| Transient thermal impedance model provided | ZthJC analytical coefficients (7-term Foster network) enable accurate IGBT/diode co-simulation |
| Rated for TC = 150°C operation | Supports compact heatsink designs in space-constrained rail traction cabinets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current press-pack diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FF600R12ME4 | IGBT-based module (not diode-only); 600 A IC, 1200 V VCE; integrated freewheeling diodes | Designed for active switching topologies (e.g., 2L-VSI), not passive rectification | Select only if replacing diode+IGBT discrete stacks with integrated half-bridges |
| DD500S12K3 | Same 1200 V rating but 500 A IFAVM, 0.095 °C/W RthJC per arm; larger AlN baseplate | Requires higher mounting torque (22 Nm) and deeper heatsink interface | Choose when system demands >300 A continuous current or tighter thermal budget |
Compared with FF600R12ME4 and DD500S12K3, DD241S12KHPSA1 offers optimal cost-per-amp and thermal simplicity for fixed-frequency, high-duty-cycle rectification where active switching is unnecessary.

FAQ
What is the mounting torque specification for DD241S12KHPSA1?
The mechanical mounting torque for the M16 bolts is 16 Nm ±15%. This ensures sufficient clamping force to maintain low-resistance pressure contact between Si pellets and copper terminals without damaging the AlN insulator. Under-torque risks thermal runaway; over-torque may crack the ceramic baseplate.
Does DD241S12KHPSA1 require gate drive or control signals?
No. DD241S12KHPSA1 is an uncontrolled power diode module with no gate terminals. It conducts automatically when forward-biased and blocks when reverse-biased. No driver circuitry, timing signals, or control logic is needed-only proper heatsinking and overvoltage protection.
Can DD241S12KHPSA1 be used in parallel configurations?
Yes, but only with matched dynamic characteristics and symmetrical busbar layout. Parallel operation requires identical mounting torque, thermal interface resistance, and stray inductance per branch. The datasheet provides transient thermal coefficients to validate current sharing under pulsed loads.
What is the meaning of "KHPSA1" in the part number DD241S12KHPSA1?
"KHPSA1" denotes: K = common-cathode configuration; H = high surge rating (9300 A); P = press-pack assembly; S = standard AlN isolation; A1 = first revision of this mechanical variant. This suffix distinguishes it from common-anode (K) or low-surge (L) versions in the same voltage/current class.
