Product details
Overview
D2450N04TXPSA1 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 2450 A average on-state current at 100 °C case temperature, 4000 A RMS on-state current, and 400 V repetitive peak reverse voltage, with a maximum junction temperature of 180 °C. Its two-sided cooling design supports high-reliability operation in 3-level NPC and phase-controlled rectifier stacks.
For engineers reviewing the D2450N04TXPSA1 datasheet, D2450N04TXPSA1 pinout, D2450N04TXPSA1 application, or D2450N04TXPSA1 equivalent, key selection criteria include its 0.0253 °C/W junction-to-case thermal resistance (two-sided), 33 kA surge current rating, 1.5 V max forward voltage at 7.7 kA, and pressure-contact Si-pellet construction for high-current busbar integration.
Technical Context
This device operates as a unidirectional, non-controlled power rectifier with no gate control or switching function. Its conduction behavior follows a defined on-state characteristic (vF = A + B·iF + C·ln(iF) + D·iF²) across 600–11,000 A at Tvj = 180 °C, enabling precise loss modeling in high-current converters.
Thermal performance is defined by analytical transient impedance ZthJC functions for anode-, cathode-, and two-sided cooling configurations. The diode exhibits 50 mA max reverse leakage at VRRM and 180 °C, and its recovery charge Qr varies from ~100 to 10,000 µAs depending on di/dt (1–100 A/µs) and peak forward current.

FAQ
What is the recommended clamping force for D2450N04TXPSA1 installation?
The datasheet specifies a mechanical clamping force range of 12–24 kN for reliable pressure contact between the Si pellet and both metal terminals. Exceeding 24 kN risks ceramic insulator fracture or pellet deformation, while forces below 12 kN increase contact resistance and localized heating. Torque-controlled hydraulic tools are strongly advised for repeatable assembly.
Does D2450N04TXPSA1 support single-sided cooling?
Yes - the datasheet provides distinct thermal parameters for anode-sided, cathode-sided, and two-sided cooling. For single-sided use, RthJC rises to 0.0414 °C/W (anode) or 0.0614 °C/W (cathode), requiring significant derating of IFAVM to maintain Tvj ≤ 180 °C. Two-sided cooling is strongly preferred for rated performance.
How is reverse recovery charge Qr characterized for this diode?
Qr is measured per JEDEC standards at Tvj = 180 °C, vR ≤ 0.5·VRRM, and vRM = 0.8·VRRM, with RC network R = 2.7 Ω, C = 1.5 µF. Measured values range from ~100 µAs (50 A, 100 A/µs) to ~10,000 µAs (1600 A, 1 A/µs), confirming soft recovery behavior suitable for low-EMI rectifier designs.
Is D2450N04TXPSA1 qualified for automotive applications?
No - this device is not AEC-Q101 qualified. While it meets industrial and traction environmental specs (Tstg = –40 to +180 °C), Infineon positions it for rail, marine, and industrial power systems. Automotive-grade equivalents require explicit AEC qualification, vibration testing per ISO 16750, and PPAP documentation - none of which apply to this part number.
