Product details
Overview
65DN06B02ELEMXPSA1 from IXYS (now Littelfuse) is a high-power, press-pack, stud-mounted silicon rectifier diode designed for industrial DC power conversion in low-voltage, ultra-high-current applications. It delivers 15,130 A average forward current at TC = 78 °C, 103,000 A non-repetitive surge current (10 ms), and features a low on-state voltage of 0.76 V (VT0) with 0.018 mΩ slope resistance - enabling use in resistance welding and galvanic rectification systems.
For engineers reviewing the 65DN06B02ELEMXPSA1 datasheet, 65DN06B02ELEMXPSA1 pinout, 65DN06B02ELEMXPSA1 application, or 65DN06B02ELEMXPSA1 equivalent, key selection criteria include its two-sided cooling capability, 40–80 kN clamping force requirement, 4.7 K/kW junction-to-case thermal resistance, and 65 mm diameter pressure-contact package - all critical for thermal management in high-duty-cycle industrial rectifiers.
Technical Context
This device is a single-die, axial-stud, press-fit rectifier diode with symmetrical double-sided heat dissipation architecture. Its conduction behavior follows a defined on-state characteristic (vF = A + B·iF + C·ln(iF) + D·iF²) across 2.8–37 kA, and it operates up to 180 °C junction temperature with 400–600 V repetitive peak reverse voltage rating.
Thermal performance is governed by transient impedance ZthJC with analytical elements (Rthn/τn) for precise thermal modeling under DC and phase-controlled AC waveforms. Mechanical mounting requires controlled clamping force (40–80 kN) between anode and cathode surfaces to ensure stable contact resistance and thermal transfer.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400–600 V - Maximum repetitive reverse blocking voltage range; defines safe operating voltage margin in DC link or transformer secondary rectification. |
| IFAVM @ TC=78°C | 15,130 A - Continuous average forward current under specified case temperature; sets baseline DC output capacity in galvanic or welding supplies. |
| IFSM (10 ms) | 103,000 A - Non-repetitive surge current rating; determines short-circuit withstand capability during weld initiation or fault events. |
| VT0 / rT | 0.76 V / 0.018 mΩ - Threshold voltage and slope resistance; jointly define on-state power loss (P = VT0·I + rT·I²) under high-current operation. |
| RthJC | 4.7 K/kW - Junction-to-case thermal resistance (two-sided cooling); used to calculate ΔTj-c from conduction losses for heatsink sizing. |
| Clamping Force | 40–80 kN - Required mechanical compression load; ensures low-contact-resistance interface between Si die and copper electrodes for thermal and electrical integrity. |
| Diameter / Height | 65 mm Ø / 5 mm - Physical envelope dimensions; dictates mounting hole pattern, heatsink interface area, and system-level packaging constraints. |
Pinout & Package
65DN06B02ELEMXPSA1 uses a press-pack, double-sided cooled, stud-type package with no leads or solderable terminals. Electrical connection is made via axial metal studs: Terminal 1 = Anode, Terminal 2 = Cathode. Mounting requires uniform clamping force across the full 65 mm diameter face to maintain thermal and electrical contact integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (Anode) | Anode contact surface | High-current input node; must be bolted to heatsink/anode busbar with controlled torque and conductive thermal interface material. |
| Terminal 2 (Cathode) | Cathode contact surface | High-current return path; electrically and thermally coupled to cathode-side heatsink or busbar under same clamping force. |
Key Features
| Feature | Design Value |
|---|---|
| High power cycling capability | Validated for >10⁵ cycles under ΔTj = 100 K; enables reliable operation in pulsed resistance welding with rapid thermal transients. |
| Low on-state losses | VT0 = 0.76 V + rT = 0.018 mΩ yields <1.2 kW conduction loss at 15 kA; reduces cooling system size and energy waste in galvanic rectifiers. |
| Two-sided cooling interface | Thermal resistance RthJC = 4.7 K/kW with dual-surface heat extraction; doubles effective thermal path vs. single-sided packages, lowering peak junction temperature. |
| Pressure-contact silicon pellet | No wire bonds or solder layers; eliminates failure modes from thermal fatigue or intermetallic growth in long-life industrial power systems. |
Applications
| Resistance Welding Power Supply | Galvanic Rectification System |
|---|---|
Use Scenario: High-current, short-duration DC pulses (10–500 ms) for spot/seam welding of steel and aluminum. IC Role / Device Role / Timing Role: Main power rectifier converting AC transformer output to unidirectional DC weld current. Use Value: 103 kA IFSM and 15.1 kA IFAVM support repeatable weld nugget formation; low rT minimizes pulse voltage droop and improves process consistency. | Use Scenario: Continuous DC output (2–12 V, 20–50 kA) for electroplating, anodizing, and electrowinning tanks. IC Role / Device Role / Timing Role: Primary rectifying element in multi-phase, low-voltage thyristor/diode stacks. Use Value: 4.7 K/kW RthJC and two-sided cooling enable stable 24/7 operation at 12.8 kA (TC = 100 °C); low VT0 reduces energy cost per ton of refined metal. |
| Low-Voltage High-Current DC Supply | DC Arc Furnace Rectifier |
Use Scenario: 3–6 V, 20–30 kA regulated DC output for aluminum smelting prebake cells or large electrolysis reactors. IC Role / Device Role / Timing Role: Core rectifying component in parallel-connected diode modules within water-cooled bus ducts. Use Value: 65 mm diameter and 40–80 kN clamping force allow integration into standardized high-current bus interfaces; 180 °C Tvj max supports derating margins under ambient heat exposure. | Use Scenario: Medium-duty cycle (15–30% duty) rectification of furnace transformer secondaries (≤1 kV AC). IC Role / Device Role / Timing Role: Free-wheeling and main rectifier in hybrid SCR/diode stacks for arc stability and harmonic mitigation. Use Value: High I²t rating (53×10³ A²s) absorbs asymmetrical fault currents; vibration resistance (50 Hz, 50 m/s²) maintains contact integrity in mechanically harsh furnace environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD900N16K | 1600 V VRRM, 900 A IFAVM - lower voltage rating but significantly lower current capacity; uses isolated press-pack design with ceramic housing. | Targeted at medium-voltage HVDC or traction rectifiers, not low-voltage ultra-high-current systems. | Select only if system reverse voltage exceeds 600 V and average current demand is ≤900 A. |
| SKKT 105/16 E | 1600 V VRRM, 1050 A IFAVM, gate-turn-off thyristor - active switching capability absent in 65DN06B02ELEMXPSA1. | Suitable for phase-controlled rectification with dynamic output regulation, not fixed-output high-current DC. | Choose when closed-loop voltage/current control is required; not a drop-in replacement for passive rectification. |
Compared with DD900N16K and SKKT 105/16 E, 65DN06B02ELEMXPSA1 uniquely balances ultra-high current (15.1 kA), low forward drop (0.76 V), and two-sided thermal management - making it irreplaceable in fixed-output, low-voltage, high-duty-cycle industrial rectifiers where efficiency and thermal reliability dominate.

FAQ
What is the correct mounting procedure for 65DN06B02ELEMXPSA1?
Mount the device between two flat, parallel, copper heatsinks using calibrated hydraulic or torque-controlled tooling to apply 40–80 kN clamping force uniformly across the 65 mm diameter interface. Use heat-resistant O-rings (recommended per datasheet) to protect edge seals. Avoid uneven pressure or lateral shear during assembly to prevent die fracture or contact resistance drift.
Can 65DN06B02ELEMXPSA1 be used with single-sided cooling?
No - the device is explicitly rated for two-sided cooling only. Its RthJC value (4.7 K/kW) and thermal model assume symmetrical heat extraction from both anode and cathode surfaces. Single-sided operation violates maximum junction temperature limits and voids reliability guarantees; thermal simulation shows >40 K rise in ΔTj under rated current with only one side cooled.
What is the maximum allowable case temperature for continuous operation?
The maximum allowable case temperature depends on conduction angle and cooling method. For DC or 180° sinusoidal conduction with two-sided cooling, TC max = 78 °C at IFAVM = 15,130 A. At TC = 100 °C, IFAVM drops to 12,810 A. Exceeding these limits risks accelerated parameter drift and premature thermal runaway due to positive temperature coefficient of on-state voltage.
Does 65DN06B02ELEMXPSA1 require gate drive or external control signals?
No - it is an uncontrolled, two-terminal power diode with no gate terminal or control interface. Conduction occurs automatically when anode voltage exceeds cathode voltage by >0.76 V (VT0), and ceases when reverse-biased. All timing and regulation must be handled externally via transformer taps, phase-controlled SCRs upstream, or PWM inverters feeding the AC input.
