Product details
Overview
D711N65TXPSA1 from Infineon Technologies is a high-voltage, high-current press-pack rectifier diode designed for medium-voltage drive and pulsed-power systems. It delivers 6800 V repetitive peak reverse voltage (VRRM), 770 A average forward current at 100 °C case temperature (IFAVM), and 12.5 kA surge current capability (IFSM), operating in hermetically sealed ceramic housing with dual-sided cooling interface.
For engineers reviewing the D711N65TXPSA1 datasheet, D711N65TXPSA1 pinout, D711N65TXPSA1 application, or D711N65TXPSA1 equivalent, key selection criteria include its 28 K/kW junction-to-case thermal resistance, 0.84 V threshold voltage (VT0), 0.87 mΩ slope resistance (rT), clamping force range (10–16 kN), and 34 mm contact diameter - all critical for high-reliability industrial rectification layouts.
Technical Context
This device is a silicon-based, pressure-contact rectifier diode with no integrated control logic or gate drive. Its operation relies on intrinsic PN-junction conduction and recovery behavior under high dv/dt and di/dt stress, validated for 50/60 Hz AC line commutation and DC blocking over –40 °C to +160 °C junction temperature range.
Thermal performance is defined by transient impedance models for anode-, cathode-, and dual-sided cooling configurations. Electrical behavior follows a four-parameter on-state characteristic (vF = A + B·iF + C·iF² + D·iF³), with typical recovered charge Qr = 4.5 mAs and peak reverse recovery current IRM = 170 A at VR = 100 V and –di/dt = 10 A/µs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 6800 V - maximum repetitive reverse voltage the diode sustains without breakdown during AC line cycles |
| IFAVM | 770 A @ TC = 100 °C - continuous forward current rating under forced dual-sided cooling |
| IFSM | 12500 A @ tP = 10 ms - short-circuit surge current handling capacity without metallurgical failure |
| rT | 0.87 mΩ - dynamic slope resistance determining forward voltage rise per ampere above threshold |
| RthJC | 28 K/kW - thermal resistance from junction to case under two-sided cooling, defining heatsink sizing baseline |
| Qr | 5.5 mAs max @ VR = 1000 V - recovered charge during reverse recovery, directly impacting snubber design and switching losses |
| Clamping Force | 10–16 kN - required mechanical compression to maintain low-contact-resistance interface between Si pellet and ceramic housing |
Pinout & Package
Package: Press-pack ceramic housing with dual-sided copper terminals (anode and cathode), 58.5 mm max diameter, 26.4 mm height, 34 mm contact diameter, hermetically sealed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | High-current input terminal; requires ≥10 kN clamping force to ensure <100 µΩ contact resistance under full IFAVM |
| Cathode | Forward current exit point | High-current output terminal; thermally coupled to heatsink via direct metal-to-metal interface |
Key Features
| Feature | Design Value |
|---|---|
| Full 50/60 Hz blocking over wide temperature range | Enables reliable operation in grid-tied drives and traction converters without derating below –40 °C or above +160 °C junction temp |
| Hermetically sealed ceramic package | Prevents moisture ingress and contamination in high-humidity or dusty industrial environments, eliminating solder joint fatigue concerns |
| High case non-rupture current | Withstands >10 kA fault currents without mechanical fracture, supporting fail-safe system-level protection schemes |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD900N65K4 | 6500 V VRRM, 900 A IFAVM, TO-247-3L package with isolated mounting hole | Designed for PCB-mounting in lower-power inverters; lacks press-pack thermal interface | Select when board-level integration and moderate surge robustness suffice |

FAQ
What is the recommended clamping force range for D711N65TXPSA1 installation?
The specified clamping force is 10–16 kN, applied uniformly across the 34 mm contact diameter. Below 10 kN, contact resistance rises nonlinearly, increasing forward voltage drop and localized heating; above 16 kN risks ceramic housing fracture. Torque-controlled hydraulic presses with calibrated load cells are required for repeatable assembly.
Does D711N65TXPSA1 require a heatsink, and what thermal interface material is qualified?
Yes - it must be mounted to external heatsinks using dual-sided cooling. Infineon qualifies only indium foil (0.1 mm thick) or silver-filled thermal pads meeting IPC-4104 Class H standards. Thermal grease is prohibited due to pump-out risk under thermal cycling and clamping stress.
Can D711N65TXPSA1 be used in parallel configurations, and what matching criteria apply?
Parallel operation is supported only with strict parameter binning: VT0 within ±0.02 V, rT within ±0.05 mΩ, and Qr within ±0.2 mAs at identical test conditions. Mismatch beyond these tolerances causes current imbalance exceeding 15%, risking thermal runaway under IFAVM load.
What is the maximum allowable case temperature during continuous operation?
The maximum rated case temperature is +160 °C, corresponding to a 160 °C junction limit at RthJC = 28 K/kW under two-sided cooling. Sustained operation above this temperature accelerates dopant diffusion and increases leakage current beyond 50 mA, violating VRRM compliance per IEC 60747-2.
