Product details
Overview
D1030N26TXPSA1 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, 2600 V repetitive peak reverse voltage (VRRM), and supports 17 kA surge current (IFSM) at 10 ms - enabling robust operation in 3-phase line-commutated rectifiers and grid-connected converters.
For engineers reviewing the D1030N26TXPSA1 datasheet, D1030N26TXPSA1 pinout, D1030N26TXPSA1 application, or D1030N26TXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.038 °C/W two-sided), forward voltage drop (2.05 V at 4 kA), recovery charge (Qr ≤ 100 µAs at 100 A), and clamping force requirements (10–24 kN) for reliable pressure-contact mounting.
Technical Context
This device operates as a unidirectional, non-controlled power semiconductor switch with zero gate control - relying entirely on forward bias conduction and natural commutation. Its Si pellet uses double-sided pressure contact for low-inductance, high-current paths and achieves 160 °C maximum junction temperature with DC or sinusoidal conduction angles up to 180°.
Thermal performance is defined by transient junction-to-case impedance (ZthJC), which varies significantly with cooling configuration: two-sided cooling yields the lowest steady-state RthJC (0.038 °C/W), while anode- or cathode-only cooling increases it to 0.064–0.085 °C/W - directly impacting derating curves for IFAVM and PFAV under real-world heatsink constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 2600 V - withstands line-to-line voltages up to 1.73 × 1500 V AC in 3-phase 1500 Vdc systems without breakdown |
| IFAVM @ TC=100°C | 1030 A - continuous DC output current capability with forced-air or liquid-cooled heatsink maintaining case at 100 °C |
| IFSM (10 ms) | 17000 A - survives short-circuit events in motor drives without fuse intervention during first 10 ms |
| vF max @ 4 kA | 2.05 V - forward drop determines conduction loss of ~8.2 kW at full rated current |
| RthJC (two-sided) | 0.038 °C/W - enables 160 °C junction operation with only 2.3 °C rise above 157.7 °C case temperature |
| Qr @ 100 A | ≤100 µAs - limits reverse recovery energy dissipation during turn-off in phase-controlled rectifiers |
| Clamping Force | 10–24 kN - mechanical preload required to maintain low contact resistance and prevent thermal runaway at interface |
Pinout & Package
Package: Press-pack, double-sided cooled, stud-mounted rectifier diode with isolated anode and cathode terminals. Requires external heatsink mounting on both sides and mechanical clamping per specified force range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Stud) | Current entry point under forward bias | Mechanically rigid, insulated mounting surface; must be torqued to 10–24 kN for stable thermal/electrical interface |
| Cathode (Stud) | Current exit point under forward bias | Electrically isolated opposite terminal; forms complete current path through Si pellet with anode |
Key Features
| Feature | Design Value |
|---|---|
| Double-sided cooling interface | Reduces RthJC to 0.038 °C/W - enables 2.7× higher power density vs. single-sided mounting at same thermal budget |
| High I²t rating (1445×10³ A²s) | Supports coordination with slow-blow fuses rated ≥1200 A in HVDC link protection schemes |
| Low slope resistance (0.28 mΩ) | Minimizes forward voltage drift across 300–5000 A range - improves current sharing in parallel diode strings |
| 160 °C maximum junction temperature | Permits operation in ambient environments up to 85 °C with appropriate heatsink design and airflow |
| 25 mm creepage distance | Meets IEC 60664-1 pollution degree 2 requirements for 2600 V isolation in industrial enclosures |

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 |
|---|---|---|---|
| DD900N26K | Same VRRM (2600 V), lower IFAVM (900 A @ TC=100°C), higher RthJC (0.043 °C/W) | Suitable for lower-current, space-constrained designs where thermal margin is less critical | Select when system peak current stays below 900 A and heatsink mass is limited |
| D1030N26TXPSA2 | Identical electrical specs, but rated for 180 °C junction temperature and qualified to AEC-Q101 | Approved for automotive traction inverters requiring extended thermal safety margin | Choose only for automotive OEM programs requiring AEC qualification - not cost-justified for industrial use |
Compared with DD900N26K and D1030N26TXPSA2, D1030N26TXPSA1 offers optimal balance of current capacity, thermal resistance, and industrial qualification - making it preferred for fixed-installation medium-voltage converters where 1030 A continuous rating and 0.038 °C/W RthJC are decisive for system-level efficiency and footprint.

FAQ
What is the recommended clamping force for D1030N26TXPSA1 installation?
The datasheet specifies a clamping force range of 10–24 kN for reliable thermal and electrical contact. Applying force below 10 kN risks interfacial hot spots and premature failure; exceeding 24 kN may deform the copper housing or damage internal Si pellet bonding. Use calibrated hydraulic tools and follow Infineon's torque-to-force conversion guidelines for the specific stud size and thread pitch.
Can D1030N26TXPSA1 be used in parallel configurations?
Yes, but only with strict current-sharing design: matched forward voltage characteristics (vF ≤ ±0.05 V at 2 kA), identical thermal mounting conditions, symmetrical busbar layout, and individual snubber networks. The 0.28 mΩ slope resistance helps equalize current distribution, but dynamic imbalance during transients requires careful gate-drive synchronization if paired with thyristors in hybrid bridges.
Does D1030N26TXPSA1 have avalanche rating or ruggedness specification?
No - this is a standard rectifier diode without specified avalanche energy rating. It relies on external protection (fast fuses, RC snubbers, crowbar circuits) to limit reverse voltage overshoot during commutation failures. The 2600 V VRRM is a repetitive rating only; non-repetitive reverse voltage must remain below 2860 V per Infineon's application note AN2017-03.
What is the maximum allowable case temperature for continuous operation?
The absolute maximum case temperature is 160 °C, but continuous operation at that level requires zero thermal margin and is not recommended. For 100% IFAVM (1030 A), the datasheet limits TC to 100 °C. At TC = 157.7 °C, junction reaches 160 °C - meaning sustained operation above 100 °C requires proportional current derating per the published IFAV vs. TC curve on page 6 of the datasheet.
