Product details
Overview
D1030N24TXPSA1 from Infineon Technologies is a high-power, press-pack silicon rectifier diode designed for industrial AC/DC conversion in medium-voltage drive systems and traction inverters. It delivers 1030 A average on-state current at TC = 100 °C, supports 2400 V repetitive peak reverse voltage (VRRM), and handles 17 kA surge current (IFSM) at 10 ms - enabling robust operation in 3-phase phase-controlled rectifiers feeding DC link capacitors in rail propulsion systems.
For engineers reviewing the D1030N24TXPSA1 datasheet, D1030N24TXPSA1 pinout, D1030N24TXPSA1 application, or D1030N24TXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.035 °C/W two-sided), forward voltage drop (1.11 V at 1 kA, Tvj max), and transient thermal impedance behavior under 50 Hz half-wave overload sequences.
Technical Context
This device is a single-die, pressure-contact, stud-mounted rectifier diode with symmetrical double-sided cooling capability. Its on-state characteristic follows a four-parameter logarithmic model (A=0.3973, B=2.062×10⁻⁴, C=0.03005, D=0.009271) across 300–5000 A, enabling precise conduction loss modeling in high-current thyristor/diode stacks.
Thermal performance is defined by dual-path junction-to-case resistance: 0.035 °C/W (two-sided), 0.061 °C/W (anode-side only), and 0.082 °C/W (cathode-side only). Transient thermal impedance ZthJC shows six analytical elements, with dominant time constants ranging from 0.272 ms to 0.999 s - critical for short-term overload coordination in line-commutated converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 2400 V - maximum repetitive reverse blocking voltage; defines compatibility with 1.7 kV-class AC line inputs after derating. |
| IFAVM @ TC=100°C | 1030 A - continuous DC current rating under forced two-sided cooling; sets minimum heatsink sizing for steady-state operation. |
| IFSM @ 10 ms | 17000 A - non-repetitive surge current capacity; determines fuse coordination and short-circuit withstand in 50/60 Hz systems. |
| vF @ 1 kA, Tvj max | 1.11 V - forward voltage at rated RMS-equivalent load; directly impacts conduction losses (P ≈ 1.11 × IFAV) in high-efficiency designs. |
| RthJC (two-sided) | 0.035 °C/W - thermal resistance from junction to case with dual-surface mounting; enables <110 °C junction rise at 1030 A. |
| I²t @ 10 ms | 1445 × 10³ A²s - surge energy handling capability; used for IGBT/diode short-circuit protection timing in series-connected stacks. |
| Tvj max | 160 °C - maximum allowable junction temperature; constrains maximum allowable thermal margin in sealed enclosures. |
Pinout & Package
Package: Press-pack, stud-mounted, double-sided cooled module with isolated anode and cathode terminals. Requires clamping force of 10–24 kN and provides 25 mm creepage distance. Weight: 285 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (stud) | Current entry point under forward bias | Mechanically rigid, thermally conductive mounting surface; must be torqued to specified clamping force for RthJC compliance. |
| Cathode (stud) | Current exit point under forward bias | Electrically isolated metal surface; serves as second thermal interface for two-sided cooling configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Four-parameter on-state model | Enables accurate conduction loss prediction from 300 A to 5000 A using vF = A + B·iF + C·ln(iF) + D·iF·ln(iF). |
| Two-sided thermal path | 0.035 °C/W RthJC allows >2000 A RMS current handling when both studs are actively cooled - doubling effective thermal capacity. |
| High surge robustness | 17 kA IFSM at 10 ms supports fault ride-through in grid-tied rectifiers without immediate device failure. |
| Low slope resistance | 0.28 mΩ rT minimizes dynamic voltage overshoot during fast current transitions in phase-controlled applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-power rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD900N24K | Same VRRM (2400 V), lower IFAVM (900 A @ TC=100°C), higher RthJC (0.042 °C/W two-sided) | Suitable for lower-duty-cycle applications with intermittent loading; less suited for continuous 1000+ A operation | Select when thermal margin is available and cost sensitivity outweighs 13% current derating. |
| D1100N24TXPSA1 | Higher IFAVM (1100 A @ TC=100°C), identical VRRM and RthJC, 5% higher vF (1.16 V @ 1 kA) | Better for sustained high-current loads but increases conduction loss by ~45 W at 1000 A | Select when system-level thermal design prioritizes current headroom over efficiency optimization. |
Compared with DD900N24K and D1100N24TXPSA1, D1030N24TXPSA1 offers optimal balance of current rating, thermal resistance, and forward voltage - making it preferred for 1000 A continuous, two-sided cooled rectifier stacks where both efficiency and reliability are constrained.

FAQ
What is the recommended clamping force for D1030N24TXPSA1 installation?
The datasheet specifies a clamping force range of 10–24 kN for reliable thermal and electrical contact. Applying 18 kN achieves optimal RthJC (0.035 °C/W) while avoiding pellet fracture. Force must be applied uniformly across both studs using calibrated torque tools and hardened washers per Infineon Application Note AN2015-07.
Can D1030N24TXPSA1 be used in single-sided cooling configurations?
Yes - it supports anode-side-only or cathode-side-only cooling, with RthJC values of 0.061 °C/W and 0.082 °C/W respectively. However, this reduces maximum IFAVM to 720 A and 580 A at TC = 100 °C, requiring significant derating and larger heatsinks compared to two-sided operation.
How does the device behave under non-sinusoidal current waveforms?
Its thermal performance accounts for waveform shape: ∆Zth increases by 0.00437 °C/W for rectangular 180° conduction and 0.00277 °C/W for sinusoidal 180° conduction versus DC. These values are additive to the base ZthJC curve and must be included in junction temperature calculations for PWM-fed or phase-angle-controlled loads.
Is D1030N24TXPSA1 compliant with AEC-Q101 or automotive standards?
No - it is not AEC-Q101 qualified. The device is designed for industrial and traction applications per IEC 60747-2 and EN 50124-1. Its -40 °C to +160 °C storage and operating temperature range supports rail and grid environments, but it lacks automotive-specific qualification testing such as humidity bias or mechanical shock profiles.
