Product details
Overview
D650N08TXPSA1 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 650 A average on-state current at TC = 100 °C, supports 800 V repetitive peak reverse voltage (VRRM), and handles 6.3 kA surge current (IFSM) at 10 ms - enabling robust operation in 3-phase bridge rectifiers for rail propulsion and grid-connected energy storage.
For engineers reviewing the D650N08TXPSA1 datasheet, D650N08TXPSA1 pinout, D650N08TXPSA1 application, or D650N08TXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.081 °C/W two-sided), forward voltage drop (1.44 V max at 1350 A), and I²t rating (198.5 × 10³ A²s at Tvj = 25 °C), all critical for thermal design and short-circuit withstand in high-current DC-link circuits.
Technical Context
This device is a single, non-controlled, planar-junction silicon rectifier with pressure-contact construction and dual-side cooling capability. Its on-state characteristic follows a four-parameter logarithmic model (A=0.54, B=1.988×10⁻⁴, C=−1.66×10⁻², D=2.007×10⁻²), enabling precise conduction loss modeling across 100–3000 A.
Thermal performance is defined by transient junction-to-case impedance ZthJC, with distinct curves for anode-, cathode-, and two-sided cooling configurations. The maximum junction temperature is rated at 180 °C, and reverse recovery charge Qr ranges from 25 µAs to 1000 µAs depending on di/dt (1–1000 A/µs) and forward current (25–800 A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum repetitive reverse blocking voltage; defines usable DC-link voltage headroom in 600 V-class systems with safety margin. |
| IFAVM @ TC=100°C | 650 A - Continuous average forward current under forced two-sided cooling; sets baseline conduction rating for steady-state operation. |
| IFRMS | 1360 A - RMS on-state current; determines thermal stress under non-sinusoidal load currents like PWM rectifier outputs. |
| IFSM (10 ms) | 6300 A - Peak non-repetitive surge current; defines short-circuit withstand capability without bond-wire fusing. |
| RthJC (two-sided) | 0.081 °C/W - Junction-to-case thermal resistance; enables accurate junction temperature prediction when mounted with specified clamping force (2.6–4.6 kN). |
| vF max @ 1350 A | 1.44 V - Maximum forward voltage at rated peak current; directly impacts conduction losses and heatsink sizing. |
| I²t (25°C) | 198.5 × 10³ A²s - Surge energy rating; used to coordinate upstream fuse protection for 10 ms fault clearing. |
Pinout & Package
Package: Press-pack, double-sided cooled, stud-mount diode with isolated anode and cathode terminals. Requires mechanical clamping (2.6–4.6 kN) onto heatsinks with thermal interface material. Weight: 75 g. Creepage distance: 10 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Stud) | Forward current entry point | Electrically isolated metal stud; must be bolted to heatsink with torque-controlled clamping for thermal and electrical contact. |
| Cathode (Stud) | Forward current exit point | Second electrically isolated stud; enables symmetrical two-sided cooling and low-inductance busbar connection. |
Key Features
| Feature | Design Value |
|---|---|
| High surge current capability | 6.3 kA IFSM (10 ms) - Supports reliable operation during motor startup surges and grid fault transients in traction converters. |
| Low thermal resistance | 0.081 °C/W RthJC (two-sided) - Enables higher power density and reduced heatsink mass compared to bolt-down alternatives. |
| Precision on-state modeling | Four-parameter vF(iF,Tvj) equation - Allows accurate loss simulation across full operating range for system-level efficiency optimization. |
| Robust reverse recovery behavior | Qr = 25–1000 µAs (di/dt-dependent) - Predictable recovery charge simplifies snubber design and EMI filtering in high-di/dt applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-power rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD650N08K | Same VRRM (800 V), identical package, but lower IFAVM (600 A @ TC=100°C) and higher RthJC (0.087 °C/W). | Suitable for lower-duty-cycle applications where peak current exceeds average rating. | Select when thermal margin exists and cost sensitivity outweighs 50 A conduction headroom. |
| SKKT650/08E | Higher VRRM (1200 V), same IFAVM (650 A), but higher vF (1.55 V) and larger RthJC (0.092 °C/W). | Better suited for 1 kV DC-link systems requiring extra reverse margin, e.g., HVDC interfaces. | Choose when system reverse voltage exceeds 850 V or when legacy SKKT footprint compatibility is required. |
Compared with DD650N08K and SKKT650/08E, D650N08TXPSA1 offers the lowest forward voltage and best thermal resistance among 800 V-class 650 A rectifiers, making it optimal for thermally constrained, high-efficiency industrial converters where 800 V blocking suffices.

FAQ
What is the recommended clamping force for D650N08TXPSA1?
The datasheet specifies a mechanical clamping force of 2.6–4.6 kN for optimal thermal and electrical contact between the device and heatsink. Exceeding 4.6 kN risks ceramic insulator fracture, while forces below 2.6 kN increase RthJC and risk localized overheating at the Si pellet interface.
Can D650N08TXPSA1 be used with single-sided cooling?
Yes - the datasheet provides separate RthJC values for anode-sided (0.132 °C/W), cathode-sided (0.203 °C/W), and two-sided (0.081 °C/W) cooling. Single-sided use reduces current rating: IFAVM drops to 420 A (anode-cooled) or 320 A (cathode-cooled) at TC = 100 °C.
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature is not fixed independently - it depends on current and cooling method. At 650 A IFAVM and two-sided cooling, TC reaches 100 °C per datasheet derating curves. The absolute limit is Tvj ≤ 180 °C, so TC must stay ≤ 100 °C when junction temperature is at maximum.
Does D650N08TXPSA1 have a specified reverse recovery time (trr)?
No - the datasheet does not specify trr. Instead, it characterizes reverse recovery via recovered charge (Qr), which ranges from 25 µAs to 1000 µAs depending on di/dt and forward current. This Qr-based specification is standard for high-power rectifiers where trr becomes ill-defined due to soft recovery behavior.
