Product details

Overview

D2700U45X122XOSA1 from Infineon Technologies is a press-pack, unclamped fast recovery diode designed for high-power HVDC and medium-voltage converter freewheeling applications. It delivers 4500 V repetitive peak reverse voltage (VRRM), 2700 A average forward current (IFAVM) at TC = 65 °C, and 48 kA surge current (IFSM), with soft turn-off behavior at di/dt up to 5000 A/µs - enabling robust operation in IGCT and IGBT-based traction and grid infrastructure systems.

For engineers reviewing the D2700U45X122XOSA1 datasheet, D2700U45X122XOSA1 pinout, D2700U45X122XOSA1 application, or D2700U45X122XOSA1 equivalent, key selection criteria include its 5.6 K/kW junction-to-case thermal resistance, 0.447 mΩ slope resistance, 140 °C maximum junction temperature, clamping force range (50–100 kN), and two-sided cooling capability for high-reliability power conversion stacks.

Technical Context

This diode operates as a hard-driven, unclamped fast recovery device optimized for high-di/dt switching in series-connected thyristor and IGCT valve stacks. Its soft turn-off behavior minimizes voltage overshoot during commutation, while its low rT (0.447 mΩ) and VT0 (1.38 V) ensure low conduction losses under DC and 50/60 Hz blocking conditions across –40 °C to +140 °C ambient.

The device uses silicon pellet pressure-contact construction with dual-sided heat dissipation, requiring mechanical clamping between copper heatsinks. Its transient thermal impedance ZthJC supports pulsed power duty cycles, with analytical R-τ network parameters provided for both anode- and cathode-sided cooling configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	4500 V - Enables use in ±1100 kV HVDC transmission valves and 3.3 kV+ medium-voltage converters.
IFAVM	2700 A @ TC = 65 °C - Sustains continuous forward conduction in high-current freewheeling paths without thermal runaway.
IFSM	48000 A @ 10 ms - Withstands short-circuit currents in faulted converter legs without case rupture.
rT	0.447 mΩ - Low slope resistance reduces forward voltage rise under high load current, minimizing I²R losses.
RthJC	5.6 K/kW (two-sided) - Enables efficient thermal coupling to liquid-cooled heatsinks in modular multilevel converters (MMC).
FRRS	Soft reverse recovery (typ.) - Limits dv/dt stress on series-connected devices during forced commutation.
Clamping Force	50–100 kN - Required mechanical preload ensures stable contact resistance and thermal interface integrity under thermal cycling.

Pinout & Package

Package: Press-pack, double-sided cooled, stud-type housing with anode and cathode terminals on opposite faces. Diameter: 121 mm; contact diameter: 86 mm; height: 26 mm; weight: ~1500 g. Requires external mechanical clamping between heatsinks.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Face 1)	Forward current entry point	High-current input terminal; must be bolted to heatsink with ≥50 kN force to maintain low RthJC and prevent hot-spotting.
Cathode (Face 2)	Forward current exit point	High-current output terminal; electrically isolated from anode via ceramic insulator; enables series stacking in valve modules.

Key Features

Feature	Design Value
Full 50/60 Hz blocking over wide temperature range	Maintains >2800 V DC reverse withstand at Tvj = 140 °C - critical for grid-synchronized HVDC converters.
High surge current capability	48 kA IFSM at 10 ms - survives AC line faults and DC side short circuits in industrial drives and STATCOMs.
Soft turn-off behavior at high di/dt	Controlled reverse recovery with FRRS typ. - suppresses voltage spikes that could trigger false triggering of adjacent thyristors.
High case non-rupture current	No mechanical failure up to rated IFSM - ensures structural integrity in multi-kiloampere valve assemblies.
Two-sided thermal path	RthJC = 5.6 K/kW with dual heatsink contact - doubles effective cooling area vs. single-sided packages, improving power density.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage, high-current freewheeling diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS MDD2700-45	Same VRRM (4500 V), lower IFAVM (2500 A), higher RthJC (6.2 K/kW), single-sided cooling only	Suitable for lower-duty-cycle applications; not rated for continuous two-sided thermal management	Select when system cooling is limited to one side and peak current demand is ≤2500 A RMS.
ABB 5SDF27H4502	Higher VRRM (4500 V), identical IFAVM (2700 A), but requires 120 kN clamping force and has larger footprint (130 mm Ø)	Better suited for legacy ABB valve platforms; incompatible with existing 121 mm mounting holes	Choose only when retrofitting into ABB-designed converter stacks with matching mechanical interface.

Compared with MDD2700-45 and 5SDF27H4502, D2700U45X122XOSA1 offers superior thermal performance under dual-sided cooling and tighter clamping force tolerance (50–100 kN), making it optimal for new-design HVDC and modular multilevel converters where thermal density and mechanical reproducibility are critical.

FAQ

What is the maximum allowable clamping force for D2700U45X122XOSA1?

The specified clamping force range is 50–100 kN. Exceeding 100 kN risks deforming the internal silicon pellet or damaging the ceramic insulator, leading to increased RthJC and premature thermal failure. Below 50 kN, contact resistance rises, causing localized heating and accelerated aging. Torque-controlled hydraulic presses are recommended for repeatable assembly.

Can D2700U45X122XOSA1 be used in single-sided cooled configurations?

Yes, but with derated performance: RthJC increases to 9.95 K/kW (anode-cooled) or 12.85 K/kW (cathode-cooled), reducing maximum sustainable IFAVM by ~22% at TC = 65 °C. The datasheet explicitly defines two-sided cooling as the reference condition; single-sided use requires full thermal simulation and validation.

What is the significance of the "XOSA1" suffix in the part number?

The "XOSA1" suffix denotes Infineon's internal revision and qualification code: "XO" indicates the 2017 revision cycle, "SA" specifies the standard-grade silicon wafer batch, and "1" identifies the first production lot under that qualification. It correlates to Revision 1.2 of the technical information document dated 2017-12-13.

Does D2700U45X122XOSA1 require gate drive or auxiliary control circuitry?

No - it is an uncontrolled, two-terminal power diode with no gate terminal. Operation depends solely on forward bias polarity and current magnitude. No driver, snubber, or control logic is needed, though external RC snubbers may be applied to manage di/dt-induced voltage transients in specific converter topologies.
