Product details
Overview
D1800N48TVFXPSA1 from Infineon Technologies is a high-power, press-pack silicon rectifier diode designed for industrial AC/DC conversion in medium- to high-voltage traction and grid applications. It delivers 1800 A average on-state current at TC = 100 °C, 4800 V repetitive peak reverse voltage (VRRM), and withstands 35 kA surge current (IFSM) at Tvj = 25 °C with 10 ms pulse width - used in HVDC converter valves and thyristor-controlled rectifier stacks.
For engineers reviewing the D1800N48TVFXPSA1 datasheet, D1800N48TVFXPSA1 pinout, D1800N48TVFXPSA1 application, or D1800N48TVFXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.0169 °C/W two-sided), forward voltage drop (2.82 V at 7.4 kA), surge rating, clamping force range (24–60 kN), and dual-sided cooling compatibility.
Technical Context
This device operates as a unidirectional, non-controlled power rectifier with a planar, diffusion-processed silicon die mounted in a pressure-contact, double-sided cooled package. Its on-state behavior follows a defined logarithmic voltage-current relationship (vF = A + B·iF + C·ln(iF) + D·iF·ln(iF)) with validated coefficients at Tvj max.
Thermal performance is characterized by analytical transient impedance ZthJC models for anode-, cathode-, and two-sided cooling configurations, enabling accurate thermal simulation under sinusoidal, rectangular, and overload pulse conditions up to 160 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 4800 V - maximum repetitive reverse blocking voltage for use in 3.3 kV+ AC line-fed converters |
| IFAVM @ TC=100°C | 1800 A - continuous DC conduction capability with two-sided heatsink cooling |
| IFSM (10 ms) | 35000 A - short-circuit robustness during fault clearing in HVDC valve modules |
| vF max @ 7.4 kA | 2.82 V - forward voltage defining conduction loss at rated peak current |
| RthJC (two-sided) | 0.0169 °C/W - thermal resistance enabling <1.5 K/W total system RthJC+RthCH under optimized mounting |
| Tvj max | 160 °C - maximum allowable junction temperature for derating curves and lifetime modeling |
| Clamping Force | 24–60 kN - mechanical load range required to maintain low contact resistance and thermal interface integrity |
Pinout & Package
Package: Press-pack, double-sided cooled, stud-mounted rectifier diode with isolated anode and cathode terminals. Requires mechanical clamping between two heatsinks; no solderable leads or PCB footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Stud 1) | Current entry point under forward bias | High-current input terminal; must be torqued to specified clamping force to ensure low RthJC and vF stability |
| Cathode (Stud 2) | Current exit point under forward bias | High-current output terminal; electrically isolated from anode; forms complete conduction path with external busbar routing |
Key Features
| Feature | Design Value |
|---|---|
| Two-sided thermal interface | Enables 0.0169 °C/W RthJC - reduces total thermal resistance by ~40% vs. single-sided cooling at same IFAVM |
| Validated surge rating | 35 kA IFSM (10 ms, Tvj = 25 °C) - supports coordination with fast-acting DC circuit breakers in converter substations |
| Defined on-state characteristic | Full vF = f(iF) equation with coefficients A=−0.7537, B=3.748×10⁻⁴, C=0.3443, D=−0.0266 - enables precise loss modeling in PLECS/Saber simulations |
| High-reliability pressure contact | Silicon pellet with controlled metallization and 24–60 kN clamping range - eliminates wirebond fatigue and enables >10⁶ thermal cycles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD900N48K | Same VRRM (4800 V), lower IFAVM (900 A @ TC=100°C), higher RthJC (0.0329 °C/W anode-side) | Targeted for lower-current, single-sided cooled designs; not suitable for 1800 A continuous duty | Select only when thermal budget allows higher RthJC and system current is ≤900 A RMS |
| SKKT 1000/48 | Lower VRRM (4200 V), identical IFAVM (1800 A), same press-pack form factor but different clamping geometry | Used in legacy Siemens converter designs; requires revalidation of mechanical interface and thermal interface paste coverage | Choose only for direct replacement in existing SKKT-based installations with verified 4200 V system margin |
Compared with DD900N48K and SKKT 1000/48, D1800N48TVFXPSA1 uniquely combines 4800 V blocking, 1800 A DC rating, and 0.0169 °C/W two-sided RthJC - making it the only option for new 3.3 kV+ converter designs requiring both high voltage headroom and high thermal efficiency.

FAQ
What is the recommended clamping force range for D1800N48TVFXPSA1?
The datasheet specifies a clamping force range of 24–60 kN. Applying force below 24 kN risks increased contact resistance and localized heating; exceeding 60 kN may deform the housing or damage internal silicon interfaces. Torque must be applied evenly using calibrated hydraulic tools and verified with strain gauges per Infineon Application Note AN2012-07.
Can D1800N48TVFXPSA1 be used in single-sided cooling configurations?
Yes, but with significant derating: RthJC rises to 0.0329 °C/W (anode-side) or 0.0320 °C/W (cathode-side), reducing maximum IFAVM to approximately 1150 A at TC = 100 °C. Dual-sided cooling is strongly preferred to achieve full rated current and minimize thermal cycling stress on the silicon die.
Does this diode have a specified reverse recovery charge (Qr)?
Yes - Qr is characterized per the datasheet: at Tvj = 160 °C, vR ≤ 0.5 VRRM, and vRM = 0.8 VRRM, Qr ranges from 100 µAs (at 100 A) to 100,000 µAs (at 3200 A), depending on di/dt. The RC test network uses R = 2.7 Ω and C = 1.5 µF, and values are plotted in Figure 7 of the datasheet.
Is D1800N48TVFXPSA1 compliant with AEC-Q101 or other automotive standards?
No - this device is not AEC-Q101 qualified. It is designed and tested for industrial and energy infrastructure applications per IEC 60747-2 and Infineon's internal high-reliability power diode standard IFBIP-D. Automotive use requires formal qualification and additional screening not performed on this part number.
