Product details

Overview

D2450N06TXPSA1 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 600 V repetitive peak reverse voltage, operating up to 180 °C junction temperature in two-sided cooled configurations.

For engineers reviewing the D2450N06TXPSA1 datasheet, D2450N06TXPSA1 pinout, D2450N06TXPSA1 application, or D2450N06TXPSA1 equivalent, key selection criteria include thermal resistance (0.0253 °C/W junction-to-case, two-sided), surge current rating (33 kA @ 10 ms), forward voltage drop (1.5 V max at 7.7 kA), and clamping force requirements (12–24 kN) for reliable pressure-contact mounting.

Technical Context

This device is a single-die, unidirectional, non-controlled power rectifier with a planar silicon PN junction and pressure-contact metallization. Its conduction behavior follows a defined on-state characteristic (v_F = A + B·i_F + C·ln(i_F) + D·i_F²) with slope resistance of 0.0975 mΩ at T_vj = 180 °C.

Thermal performance is defined by transient junction-to-case impedance Z_thJC, with analytical parameters provided for anode-, cathode-, and two-sided cooling. Reverse recovery charge Q_r is specified under controlled RC-network conditions (R = 2.7 Ω, C = 1.5 µF) and varies with di/dt and peak forward current.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - maximum repetitive reverse blocking voltage; defines DC link voltage rating in 3-phase rectifiers
I_FAVM @ T_C = 100 °C	2450 A - continuous DC conduction capability under industrial heatsink conditions
I_FRMS	5190 A - RMS current handling for sinusoidal or pulsed loads; critical for I²t-based fuse coordination
I_FSM @ t_P = 10 ms	33000 A - short-circuit withstand level; determines protection device sizing in fault scenarios
R_thJC (two-sided)	0.0253 °C/W - thermal path efficiency when mounted between two heatsinks; enables high-power density layouts
v_F max @ i_F = 7.7 kA	1.5 V - forward voltage at peak conduction; directly impacts conduction loss and thermal design margin
Q_r @ -di/dt = 100 A/µs	~100 µAs - recovered charge affecting snubber sizing and commutation losses in phase-controlled rectifiers

Pinout & Package

Package: Press-pack, double-side cooled, stud-mounted rectifier with isolated anode and cathode terminals. Requires mechanical clamping force of 12–24 kN for low-resistance thermal and electrical contact.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Stud)	Current entry point during forward conduction	Must be electrically isolated and thermally coupled to heatsink; polarity-sensitive mounting
Cathode (Stud)	Current exit point during forward conduction	Opposite terminal to anode; forms complete conduction path through silicon die

Key Features

Feature	Design Value
Two-sided thermal interface	Enables 0.0253 °C/W R_thJC, doubling heat extraction vs. single-sided mounting
High I²t rating (5445 × 10³ A²s)	Supports robust short-circuit protection coordination without premature fuse clearing
Low slope resistance (0.0975 mΩ)	Minimizes forward voltage rise under overload, improving efficiency at high current
180 °C maximum junction temperature	Allows operation in high-ambient environments such as rail traction cabinets or industrial furnaces
Pressure-contact Si pellet	Eliminates wire bonds and solder layers, enhancing reliability under thermal cycling stress

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 M2450N06X	Same V_RRM (600 V), lower I_FAVM (2200 A @ 100 °C); R_thJC = 0.027 °C/W (two-sided)	Slightly reduced continuous current capacity; requires tighter thermal margin	Select when legacy IXYS footprint compatibility is required and 250 A derating is acceptable
Mitsubishi CM2450N060	Identical I_FAVM and V_RRM; higher v_F (1.65 V max @ 7.7 kA); R_thJC = 0.0285 °C/W	Higher conduction loss increases heatsink size by ~8% at full load	Preferable only if Mitsubishi's qualification history in specific rail OEM programs mandates use

Compared with M2450N06X and CM2450N060, D2450N06TXPSA1 offers the lowest forward voltage and best thermal resistance, enabling higher power density and lower system-level cooling cost in new designs.

FAQ

What is the required clamping force for D2450N06TXPSA1 installation?

The device requires a mechanical clamping force between 12 kN and 24 kN to ensure low-contact-resistance thermal and electrical interfaces. Under-torque risks thermal runaway; over-torque may deform the housing or damage internal pressure contacts. Use calibrated torque tools and follow Infineon's mounting sequence: pre-torque → hold → final torque.

Can D2450N06TXPSA1 be used in single-sided cooled configurations?

Yes, but with significant derating: R_thJC rises to 0.0414 °C/W (anode-cooled) or 0.0614 °C/W (cathode-cooled), reducing I_FAVM to approximately 1520 A or 1030 A respectively at T_C = 100 °C. Two-sided cooling is strongly recommended for rated performance.

Does D2450N06TXPSA1 have a specified reverse recovery time (t_rr)?

No - this is a standard (non-fast) recovery rectifier; datasheet specifies recovered charge Q_r instead. Q_r ranges from ~50 µAs to ~100 µAs depending on -di/dt and i_FM. For applications requiring soft recovery or low EMI, a dedicated soft-recovery diode or active snubbing is necessary.

Is D2450N06TXPSA1 qualified to AEC-Q101 or similar automotive standards?

No - it is not AEC-Q101 qualified. The device is designed for industrial and traction applications per Infineon's internal IFBIP specification. While it meets harsh-environment requirements (T_stg = –40 to +180 °C), formal automotive qualification is absent; use in automotive requires additional customer-level validation.
