Product details

Overview

D2450N02TXPSA1 from Infineon Technologies is a high-power, press-pack, dual-plate rectifier diode designed for industrial AC/DC conversion in medium-voltage drive systems and traction inverters. It delivers 2450 A average on-state current at 100 °C case temperature, 4000 A RMS on-state current, and 400 V repetitive peak reverse voltage, operating up to 180 °C junction temperature in two-sided cooled configurations.

For engineers reviewing the D2450N02TXPSA1 datasheet, D2450N02TXPSA1 pinout, D2450N02TXPSA1 application, or D2450N02TXPSA1 equivalent, key selection criteria include thermal resistance (0.0253 °C/W j-to-case, two-sided), surge capability (33 kA @ 10 ms), forward voltage (1.5 V @ 7.7 kA), and clamping force requirements (12–24 kN) for reliable pressure-contact mounting.

Technical Context

This device is a silicon-based, planar, fast-recovery rectifier optimized for phase-controlled rectification and line-commutated inverters. Its on-state characteristic follows a four-parameter logarithmic model (A=1.154, B=3.499×10⁻⁵, C=−0.1228, D=0.01338) across 600–11,000 A, enabling precise conduction loss modeling under heavy-duty sinusoidal and rectangular waveforms.

Thermal performance is defined by analytical transient impedance functions for anode-, cathode-, and two-sided cooling modes, with DC thermal resistance varying from 0.0240 °C/W (anode-side) to 0.0614 °C/W (cathode-side). Reverse recovery charge Q_r ranges from 100 µAs to 10,000 µAs depending on di/dt (1–100 A/µs) and forward current (50–1600 A), critical for snubber design in high-energy switching circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum repetitive reverse blocking voltage; defines usable DC bus voltage headroom in 3-phase 400 VAC rectifiers.
I_FAVM @ T_C=100 °C	2450 A - Continuous average forward current rating under forced two-sided cooling; sets base-load capacity for motor drives.
I_FRMS	5190 A - RMS on-state current; determines I²t withstand for short-circuit protection coordination.
I_FSM @ 10 ms	33,000 A - Non-repetitive surge current; supports fault ride-through during grid transients or inverter shoot-through events.
R_thJC (two-sided)	0.0253 °C/W - Junction-to-case thermal resistance; enables thermal design of heatsink interface for ≤180 °C max junction operation.
v_F @ 7.7 kA	1.5 V - Forward voltage at peak conduction; directly impacts conduction loss (P_cond ≈ I × v_F) at rated overload conditions.
Q_r @ 800 A, −di/dt = 10 A/µs	~1000 µAs - Recovered charge; governs turn-off losses and EMI generation in commutation circuits.
T_{vj max}	180 °C - Maximum junction temperature; allows operation in high-ambient industrial environments with derating.

Pinout & Package

Package: Press-pack, dual-plate, stud-mounted rectifier diode with isolated anode and cathode plates. Requires mechanical clamping force of 12–24 kN between copper heatsinks. Weight: 160 g. Creepage distance: 9 mm.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Plate 1)	Forward current entry point	High-current input terminal; must be thermally and electrically bonded to heatsink via pressure contact.
Cathode (Plate 2)	Forward current exit point	High-current output terminal; electrically isolated from anode; requires separate heatsink interface.

Key Features

Feature	Design Value
Two-sided cooling architecture	Enables 0.0253 °C/W R_thJC, reducing thermal bottleneck in high-power converters versus single-sided packages.
High I²t rating (5445 × 10³ A²s)	Supports coordination with upstream fuses and circuit breakers in 6-pulse rectifier banks without nuisance tripping.
Low slope resistance (0.0975 mΩ)	Minimizes forward voltage drift with current, improving efficiency linearity across 600–11,000 A conduction range.
180 °C maximum junction temperature	Permits operation in harsh environments (e.g., traction underhood, industrial furnace controls) with extended lifetime at elevated ambient.
Pressure-contact Si pellet	Eliminates wire bonds and solder joints, enhancing reliability under thermal cycling and vibration in rail and energy applications.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS MDD2450N02T	Same V_RRM (400 V), identical I_FAVM (2450 A), but higher R_thJC (0.028 °C/W) and lower I_FSM (30 kA).	Requires larger heatsink surface area to achieve same thermal margin; less robust for repeated short-circuit events.	Select when cost sensitivity outweighs marginal thermal/surge margin loss and IXYS ecosystem integration is preferred.
ABB 5SNA 2450N0200	Identical package footprint and clamping specs; slightly lower v_F (1.45 V @ 7.7 kA) but narrower Q_r data availability.	Better conduction efficiency at peak load; limited public Q_r vs. di/dt curves hinder snubber optimization in fast-switching topologies.	Select for pure rectification where minimal conduction loss dominates; avoid in line-commutated inverters requiring precise Q_r-based timing.

Compared with MDD2450N02T and 5SNA2450N0200, D2450N02TXPSA1 offers superior thermal resistance and surge rating-critical for mission-critical traction and industrial drives-while maintaining full interchangeability in press-pack mounting and electrical interface.

FAQ

What is the required clamping force for D2450N02TXPSA1 installation?

The device requires a mechanical clamping force between 12 kN and 24 kN applied uniformly across its anode and cathode plates. This ensures low-contact-resistance thermal paths and prevents delamination under thermal cycling. Force below 12 kN risks excessive R_thCH and localized hot spots; above 24 kN may deform copper interfaces or damage internal Si pellet bonding.

Can D2450N02TXPSA1 be used in single-sided cooling configurations?

Yes, but with significant derating: R_thJC rises to 0.0414 °C/W (anode-side) or 0.0614 °C/W (cathode-side), reducing I_FAVM to approximately 1650 A and 1100 A respectively at T_C = 100 °C. Two-sided cooling is strongly recommended to achieve full rated current and thermal margin.

What is the typical reverse recovery charge Q_r at 400 A and −di/dt = 50 A/µs?

Per the datasheet Q_r diagram, at i_F = 400 A and −di/dt = 50 A/µs, Q_r is approximately 3200 µAs. This value is measured at T_vj = 180 °C, v_R ≤ 0.5 V_RRM, and v_RM = 0.8 V_RRM, using an RC network (R = 2.7 Ω, C = 1.5 µF).

Is D2450N02TXPSA1 qualified for automotive applications?

No-it is not AEC-Q101 qualified. While it meets industrial and traction standards (IEC 61800, EN 50124), its qualification scope excludes automotive safety-critical systems. For automotive use, Infineon recommends the AEC-Q101-certified IDH08SG120C1XKSA1 or similar discrete diodes with validated automotive stress testing.
