Product details
Overview
38DN06B02ELEMXPSA1 from IXYS (now Littelfuse) is a high-power, press-pack, stud-mounted silicon rectifier diode designed for bidirectional heat sinking in industrial DC power conversion. It delivers 5140 A average forward current at TC = 113 °C, 400–600 V repetitive peak reverse voltage, and features low on-state losses with VT0 = 0.74 V and rT = 0.049 mΩ - enabling use in resistance welding and galvanic rectification systems.
For engineers reviewing the 38DN06B02ELEMXPSA1 datasheet, 38DN06B02ELEMXPSA1 pinout, 38DN06B02ELEMXPSA1 application, or 38DN06B02ELEMXPSA1 equivalent, key selection criteria include clamping force range (15–30 kN), junction-to-case thermal resistance (9.6 K/kW), cathode diameter (35 mm), maximum junction temperature (180 °C), and surge current rating (37.4 kA @ 10 ms).
Technical Context
This device is a two-terminal, unidirectional, planar-junction silicon rectifier optimized for high-current, low-voltage DC applications where forced or liquid cooling is applied to both anode and cathode surfaces. Its pressure-contact construction eliminates solder joints, supporting high power cycling capability and mechanical robustness under vibration (50 Hz, 50 m/s²).
The diode operates with a defined on-state characteristic (vF = A + B·iF + C·ln(iF) + D·iF²), exhibits 50 mA max reverse leakage at VRRM and Tvj max, and maintains thermal stability across -40 °C to +180 °C storage and operating ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400–600 V: Maximum repetitive reverse blocking voltage - defines safe AC/DC line isolation margin in rectifier bridges. |
| IFAVM @ TC=113 °C | 5140 A: Continuous DC forward current limit - sets base-load capacity for galvanic or welding supplies. |
| IFSM @ 10 ms | 37400 A: Non-repetitive surge current - determines short-circuit withstand in uncontrolled rectifiers. |
| VT0 / rT | 0.74 V / 0.049 mΩ: Threshold voltage and slope resistance - directly determines conduction loss (P = VT0·I + rT·I²) at high current. |
| RthJC | 9.6 K/kW (two-sided): Junction-to-case thermal resistance - governs required heatsink thermal conductance for thermal design. |
| Clamping Force | 15–30 kN: Required mechanical compression - ensures low-contact-resistance interface between Si pellet and metal contacts. |
| Tvj max | 180 °C: Absolute maximum junction temperature - constrains allowable power dissipation and cooling system design. |
Pinout & Package
38DN06B02ELEMXPSA1 uses a press-pack, double-sided cooled, stud-mounted package with 38 mm outer diameter, 35 mm cathode diameter, and 4 mm height. It has two terminals: anode (stud side) and cathode (flat contact side), requiring controlled clamping force (15–30 kN) for reliable thermal and electrical interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Stud) | Forward current entry point | Mechanically integrated stud serves as current path and heatsink interface - must be torqued to specified clamping force. |
| Cathode (Flat surface) | Forward current exit point | 35 mm-diameter copper contact surface - requires matched heatsink flatness and thermal interface material for bidirectional cooling. |
Key Features
| Feature | Design Value |
|---|---|
| High power cycling capability | Enables >10⁵ thermal cycles in resistance welding without bond degradation due to pressure-contact construction. |
| Low on-state losses | VT0 = 0.74 V and rT = 0.049 mΩ minimize conduction loss at 5–10 kA, reducing heatsink size and cooling cost. |
| Bidirectional cooling support | Two-sided thermal interface allows symmetric heat extraction - improves thermal derating and enables compact stack designs. |
| Vibration resistance | Rated for 50 Hz / 50 m/s² - suitable for mobile or industrial equipment subject to mechanical shock and harmonic excitation. |
Applications
| Resistance Welding Power Supply | Galvanic Rectification System |
|---|---|
Use Scenario: High-duty-cycle, pulsed DC current delivery to welding electrodes in spot or seam welders. IC Role / Device Role / Timing Role: Main power rectifier in uncontrolled three-phase bridge - conducts full load current during conduction angle. Use Value: 37.4 kA IFSM and 5140 A IFAVM sustain repeated 10–100 ms weld pulses without thermal runaway or contact fatigue. | Use Scenario: Electroplating and anodizing lines requiring stable low-voltage, ultra-high-current DC. IC Role / Device Role / Timing Role: Primary rectifying element in transformer-rectifier sets - converts AC secondary to regulated DC output. Use Value: Low rT (0.049 mΩ) reduces voltage drop and power loss at 8–12 kA RMS, improving energy efficiency and electrolyte stability. |
| Low-Voltage High-Current DC Supply | Industrial Electrolysis Plant |
Use Scenario: DC bus feeding large induction heating or arc furnace control systems. IC Role / Device Role / Timing Role: Unidirectional current valve in multi-diode parallel stacks - handles continuous conduction with minimal forward drop. Use Value: 180 °C Tvj max and 9.6 K/kW RthJC allow operation at elevated ambient temperatures with air- or water-cooled heatsinks. | Use Scenario: Chlor-alkali production cells demanding fault-tolerant, long-life rectification. IC Role / Device Role / Timing Role: Core rectifier in modular, redundant thyristor/diode hybrid converters - provides fail-safe DC path. Use Value: Pressure-contact construction avoids solder joint failure modes, extending service life beyond 15 years in corrosive chemical 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. | Designed for medium-voltage HVDC links, not optimized for <600 V, >5 kA low-loss operation. | Use only if system requires higher blocking voltage and can accept reduced current density and higher conduction loss. |
| SKKH 105/16 E | 1600 V VRRM, 1050 A IFAVM, press-pack - same mechanical interface but 5× lower current rating. | Targeted at gate-turn-off (GTO) compatible stacks; lacks thermal derating for sustained 5+ kA DC. | Select when replacing legacy GTO-based rectifier modules - not suitable as direct replacement for 38DN06B02ELEMXPSA1's current class. |
Compared with DD900N16K and SKKH 105/16 E, 38DN06B02ELEMXPSA1 uniquely supports >5 kA average current at ≤600 V with sub-1 V forward drop and bidirectional cooling - making it irreplaceable in high-efficiency, high-reliability galvanic and welding systems.

FAQ
What is the recommended clamping force for 38DN06B02ELEMXPSA1 installation?
The datasheet specifies a clamping force range of 15–30 kN. Applying force within this window ensures optimal thermal contact resistance and mechanical stability without damaging the silicon pellet or housing. Use calibrated hydraulic tools and follow Littelfuse's mounting procedure - under-torque increases RthJC; over-torque risks die fracture.
Can 38DN06B02ELEMXPSA1 be used with single-sided cooling?
No - its thermal specifications (RthJC = 9.6 K/kW) assume two-sided cooling. Single-sided operation degrades thermal performance significantly: RthJC rises to ≥15 K/kW, limiting IFAVM to ~3200 A at TC = 113 °C. Bidirectional heatsinking is mandatory to achieve rated current and reliability.
Is a heat-resistant O-ring required for 38DN06B02ELEMXPSA1?
Yes - the manufacturer explicitly recommends protecting the diode with a heat-resistant O-ring (e.g., silicone or fluorosilicone rated to ≥200 °C) to prevent ingress of coolant, dust, or process chemicals into the press-pack cavity, which could cause arcing or corrosion at high voltage stress points.
Does 38DN06B02ELEMXPSA1 have avalanche capability?
No - it is a standard PN junction rectifier diode without designed avalanche energy rating. It must be protected against overvoltage transients using external snubbers or crowbar circuits. The 50 mA reverse leakage at VRRM confirms no intentional avalanche design; operation beyond VRRM risks irreversible junction breakdown.
