Product details

Overview

D1800N40TVFXPSA1 from Infineon Technologies is a high-power, press-pack silicon rectifier diode designed for industrial AC/DC conversion in medium- to high-voltage thyristor-controlled rectifiers and HVDC converter valves. It delivers 1800 A average on-state current at 100 °C case temperature, supports 4000 V repetitive peak reverse voltage (VRRM), and withstands 35 kA surge current (10 ms, Tvj = 25 °C), making it suitable for grid-scale power transmission systems and traction rectification.

For engineers reviewing the D1800N40TVFXPSA1 datasheet, D1800N40TVFXPSA1 pinout, D1800N40TVFXPSA1 application, or D1800N40TVFXPSA1 equivalent, key selection criteria include its two-sided cooling capability, 0.0169 °C/W junction-to-case thermal resistance, 2.82 V max forward voltage at 7.4 kA, and compatibility with forced-air or liquid-cooled heat sinks in dual-anode/cathode mounting configurations.

Technical Context

This device operates as a unidirectional, non-controlled power rectifier with a planar-diffused silicon die and pressure-contact metallization. Its on-state behavior follows a defined logarithmic characteristic (vF = A + B·iF + C·ln(iF) + D·iF·ln(iF)), enabling precise conduction loss modeling across 500–9000 A. The diode exhibits low slope resistance (0.253 mΩ) and a threshold voltage of 0.85 V at maximum junction temperature.

Thermal performance is defined for three mounting modes: two-sided, anode-sided, and cathode-sided cooling. Transient thermal impedance data (ZthJC) is provided analytically for pulse durations from 0.184 ms to 6.11 s, supporting I²t-based short-circuit coordination and overload duty-cycle analysis in line-commutated converters.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-power rectifier applications.

Alternative PartTechnical DifferenceApplication DifferenceSelection Advice
DD900N40K4000 V VRRM, 1800 A IFAVM, but single-sided (anode-cooled only); RthJC = 0.0329 °C/W.Requires larger heatsink area or higher coolant flow; unsuitable for symmetric two-sided thermal management.Select when space constraints prevent dual-stud mounting or when cost sensitivity outweighs thermal optimization.
SKKT 1000/404000 V VRRM, 1000 A IFAVM; lower current rating; uses different press-pack housing (SKiiP module-compatible).Limited to lower-power converter arms; requires redesign of clamping hardware and thermal interface.Choose for modular SKiiP-based systems where board-level integration and standardized footprint are prioritized over raw current density.

Compared with DD900N40K and SKKT 1000/40, D1800N40TVFXPSA1 offers superior thermal efficiency and higher continuous current capability in dual-cooled configurations, making it optimal for new-build HVDC and traction projects where thermal headroom and long-term reliability are critical.

FAQ

What is the recommended clamping force for D1800N40TVFXPSA1 installation?

The datasheet specifies a mechanical clamping force range of 24–60 kN for reliable thermal and electrical contact. Use calibrated hydraulic tools to achieve 45±5 kN for standard two-sided cooling setups. Exceeding 60 kN risks die fracture; below 24 kN increases contact resistance and local heating at the pressure interface.

Can D1800N40TVFXPSA1 be used in single-sided cooling configurations?

Yes - the datasheet provides separate RthJC values for anode-sided (0.0329 °C/W) and cathode-sided (0.0329 °C/W) cooling. However, IFAVM drops to 1200 A at TC = 100 °C in single-sided mode, and transient thermal impedance rises significantly beyond 100 ms, limiting overload capability.

What is the typical reverse recovery charge Qr at rated conditions?

Qr varies with di/dt and temperature: at Tvj = 160 °C, vR = 0.8·VRRM, and −di/dt = 1000 A/µs, Qr ≈ 25,000 µAs. At lower −di/dt (e.g., 100 A/µs), Qr increases to ~100,000 µAs. These values are measured using an RC network (R = 2.7 Ω, C = 1.5 µF).

Does D1800N40TVFXPSA1 require gate drive or external triggering?

No - it is a passive, uncontrolled rectifier diode with no gate terminal. Conduction begins automatically when anode voltage exceeds cathode voltage by >0.85 V (threshold), and ceases when current falls below holding level. It does not require driver circuitry, unlike thyristors or IGBTs.
