Product details
Overview
ND260N12KHPSA1 from Semikron is a press-pack dual-diode rectifier module rated for 260 A average on-state current (IFAVM), 1200 V repetitive peak reverse voltage (VRRM), and 410 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 with forced-air or natural convection cooling.
For engineers reviewing the ND260N12KHPSA1 datasheet, ND260N12KHPSA1 pinout, ND260N12KHPSA1 application, or ND260N12KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.170 °C/W), maximum junction temperature (150 °C), surge current rating (9.5 kA), threshold voltage (0.7 V), and pressure-contact Si pellet construction with AlN isolation.
Technical Context
This dual-diode module implements a bipolar silicon rectifier structure with pressure-contact die assembly and aluminum nitride (AlN) internal insulation. It supports both B2 (two-pulse) and B6 (six-pulse) bridge topologies, delivering up to 1400 A output current under forced-air cooling (KM17/Papst 4650 heatsink) and 600 A under natural convection (KM17/60W).
Thermal performance is defined by transient junction-to-case impedance ZthJC (analytical R–τ model provided), with DC RthJC = 0.170 °C/W per module and case-to-heatsink resistance RthCH = 0.04 °C/W. The device operates across –40 °C to +150 °C case temperature range and withstands 3.6 kV RMS insulation test voltage at 50 Hz for 1 second.
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 line-to-line. |
| IFAVM | 260 A - Average forward current per arm at TC = 100 °C; sets continuous power handling in industrial motor drives and UPS systems. |
| IFRMSM | 410 A - RMS forward current rating; determines I²t-based thermal stress during non-sinusoidal load cycles. |
| RthJC | 0.170 °C/W - Junction-to-case thermal resistance per module; enables thermal modeling for heatsink sizing and derating curves. |
| vF max | 1.32 V - Maximum forward voltage at Tvj = 150 °C and iF = 800 A; directly impacts conduction loss and efficiency in high-current operation. |
| IFS M | 9.5 kA - Non-repetitive surge current (10 ms, Tvj = 25 °C); supports short-circuit ride-through in medium-voltage drive inverters. |
| Qr | Measured recovered charge dependent on -di/dt and iFM; critical for snubber design and commutation loss estimation in phase-controlled rectifiers. |
| VISOL | 3.6 kV RMS - Insulation test voltage (50 Hz, 1 s); confirms suitability for Class II isolation in grounded systems. |
Pinout & Package
ND260N12KHPSA1 is housed in a press-pack module with two isolated diode arms sharing a common baseplate. Electrical terminals are M2 screw connections (12 Nm torque) for anode and cathode per arm; mechanical mounting uses M1 screws (5 Nm torque). Internal Si pellets use pressure contact and AlN ceramic isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode Arm 1 (A1) | Input terminal for first diode arm | Connects to AC phase input in B6 configuration; rated for full 260 A average current and 1200 V blocking. |
| Cathode Arm 1 (K1) | Output terminal for first diode arm | Joins common DC+ bus; shares baseplate thermal path with Arm 2. |
| Anode Arm 2 (A2) | Input terminal for second diode arm | Connects to second AC phase in B6; electrically isolated from Arm 1 but thermally coupled via shared case. |
| Cathode Arm 2 (K2) | Output terminal for second diode arm | Joins same DC+ bus as K1; enables dual-arm parallel operation or independent B2/B6 topology routing. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact Si die | Eliminates wire bonds and solder layers, improving thermal cycling reliability and reducing parasitic inductance in high-dI/dt applications. |
| AlN internal isolation | Provides 3.6 kV RMS insulation strength and low thermal resistance (0.04 °C/W case-to-heatsink), enabling compact stacked-module designs. |
| Dual-arm architecture | Supports flexible B2 or B6 rectification without external paralleling; each arm independently rated for 260 A / 1200 V. |
| Transient thermal model | Supplied R–τ network (7-element ZthJC) allows accurate dynamic junction temperature prediction under pulsed loads. |
| Wide operating temperature | Rated from –40 °C to +150 °C case temperature, supporting deployment in harsh industrial enclosures without active derating. |

FAQ
What is the maximum allowable case temperature for ND260N12KHPSA1?
The maximum allowable case temperature is +150 °C, matching the maximum junction temperature (Tvj max = 150 °C) due to its pressure-contact construction and low RthJC. Operation above this limit risks irreversible degradation of the AlN isolation and Si die metallization, even with adequate heatsinking.
Can ND260N12KHPSA1 be used in a single-phase full-wave bridge?
Yes - ND260N12KHPSA1 contains two fully isolated diode arms, making it suitable for single-phase full-wave (B2) rectification. Each arm handles one half-cycle; the common cathode configuration allows direct connection to a shared DC+ rail, simplifying layout versus discrete diodes.
What is the recommended heatsink mounting torque for ND260N12KHPSA1?
The mechanical mounting torque for M1 screws is 5 Nm ±15 %. This ensures uniform pressure across the Si pellet and AlN interface without cracking the ceramic or deforming the baseplate. Torque must be applied in a crisscross pattern and verified with a calibrated torque wrench.
Does ND260N12KHPSA1 require gate drive or control signals?
No - ND260N12KHPSA1 is an uncontrolled rectifier module with no gate or control terminals. It conducts when forward-biased and blocks when reverse-biased, relying solely on external circuit topology (e.g., B6 transformer secondary) for commutation timing and current path selection.
