Product details
Overview
D3041N65TXPSA1 from Infineon Technologies is a high-voltage, high-current press-pack rectifier diode designed for medium-voltage drive and converter systems. It delivers 6800 V repetitive peak reverse voltage (VRRM), 2930 A average forward current at 100 °C case temperature (IFAVM), and 57 kA surge current capability (IFSM), operating in crowbar and high-power rectification roles within industrial motor drives and traction converters.
For engineers reviewing the D3041N65TXPSA1 datasheet, D3041N65TXPSA1 pinout, D3041N65TXPSA1 application, or D3041N65TXPSA1 equivalent, key selection criteria include its hermetically sealed ceramic package, two-sided cooling thermal design (RthJC = 7.5 K/kW), 36–52 kN clamping force requirement, and 121 mm diameter mechanical footprint-critical for high-reliability, high-current power conversion layouts.
Technical Context
This device is a silicon-based, pressure-contact rectifier diode with no integrated gate or control logic. Its conduction behavior follows a defined on-state characteristic (vF = A + B·iF + C·iF² + D·iF³) with VT0 = 0.84 V and rT = 0.215 mΩ at Tvj max, enabling precise forward voltage modeling under high-current DC and line-frequency AC blocking conditions.
Thermally, it supports bidirectional heat extraction via anode and cathode surfaces, with transient thermal impedance ZthJC analytically characterized across seven time constants. Its 160 °C maximum junction temperature and -40 to +160 °C operating range support stable operation in harsh industrial environments without derating penalties typical of lower-grade packages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 6800 V - Withstands repetitive 6.8 kV reverse voltage during AC line commutation in medium-voltage converters. |
| IFAVM @ TC=100°C | 2930 A - Sustains continuous DC forward current up to 2.93 kA with case temperature maintained at 100 °C. |
| IFSM (10 ms) | 57000 A - Handles short-circuit fault currents without destructive failure in crowbar protection circuits. |
| VT0 / rT | 0.84 V / 0.215 mΩ - Threshold voltage and slope resistance define low-loss conduction profile for accurate thermal and loss modeling. |
| RthJC (two-sided) | 7.5 K/kW - Thermal resistance from junction to case enables efficient bidirectional heatsinking in press-fit assemblies. |
| Clamping Force | 36–52 kN - Required mechanical compression ensures stable electrical contact and thermal interface integrity under thermal cycling. |
| Qr (VR=1000 V) | 11 mAs - Recovered charge determines switching losses and snubber sizing in forced-commutated rectifier topologies. |
Pinout & Package
Hermetically sealed ceramic press-pack package with two electrically isolated metal terminals: Anode (top surface) and Cathode (bottom surface). Requires external mechanical clamping (36–52 kN) and thermal interface material on both sides for operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Top-side copper surface; must be clamped and thermally coupled to heatsink in bidirectional cooling configuration. |
| Cathode | Forward current exit point | Bottom-side copper surface; serves as second thermal path and return node for high-current DC bus connections. |
Key Features
| Feature | Design Value |
|---|---|
| Full 50/60 Hz blocking over wide temperature range | Stable VRRM ≥ 6500 V from -40 °C to 160 °C junction, eliminating derating in variable-speed drive applications. |
| High DC blocking stability | Reverse leakage ≤ 100 mA at VRRM and Tvj max ensures minimal standby power loss in HVDC link rectifiers. |
| High surge current capability | IFSM = 57 kA (10 ms) supports reliable fault clearing in industrial power systems without fuse coordination dependency. |
| Hermetically sealed ceramic package | Eliminates moisture ingress and partial discharge risk in high-humidity or contaminated environments (e.g., marine converters). |
| High case non-rupture current | Withstands mechanical stress from repeated high-di/dt events without housing fracture-critical for crowbar reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, high-current rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD900N16K | VRRM = 1600 V, IFAVM = 900 A @ TC=100°C - lower voltage/current rating, TO-247 packaged. | Suitable only for low-medium voltage (<2 kV) UPS or welding supplies; not scalable to MV drive use cases. | Select only when system VRRM < 2 kV and space-constrained PCB mounting is required. |
| SKKH 105/16 E | VRRM = 1600 V, IFAVM = 105 A @ TC=85°C - module-based, lower thermal performance (RthJC = 12.5 K/kW). | Designed for compact inverters with integrated gate drivers; lacks press-pack mechanical robustness for crowbar duty. | Prefer for servo drives where integration and fast switching outweigh surge endurance requirements. |
Compared with DD900N16K and SKKH 105/16 E, D3041N65TXPSA1 uniquely supports 6.8 kV blocking and 2.9 kA continuous conduction in a field-serviceable press-pack form factor-making it irreplaceable in medium-voltage industrial rectification where reliability under fault stress is non-negotiable.

FAQ
What is the required clamping force for D3041N65TXPSA1 installation?
The device requires a mechanical clamping force between 36 kN and 52 kN to ensure optimal electrical contact resistance and thermal interface performance. Under-torque risks increased forward voltage and localized heating; over-torque may deform ceramic housing or damage internal silicon pellet bonding. Use calibrated hydraulic tools and follow Infineon's torque sequence specified in Application Note AN2014-007.
Can D3041N65TXPSA1 be used in single-sided cooled configurations?
Yes, but with significant thermal derating: RthJC rises to 13.3 K/kW (anode-cooled) or 17.2 K/kW (cathode-cooled), reducing IFAVM by ~30% at TC = 100 °C. Bidirectional cooling is strongly recommended to maintain rated current and avoid hot-spot formation. Mounting must use symmetric, flat heatsinks with matched surface finish (Ra ≤ 0.8 µm) on both sides.
What is the maximum allowable reverse recovery dv/dt for this diode?
D3041N65TXPSA1 has no specified dv/dt rating because it is a standard recovery (non-fast) rectifier diode. Its reverse recovery behavior is characterized by Qr = 11 mAs and IRM = 300 A under standardized test conditions (VR = 1000 V, -di/dt = 10 A/µs). For forced-commutated applications, external snubbers must limit dv/dt to ≤ 50 V/µs to prevent unclamped inductive turn-off oscillation.
Does D3041N65TXPSA1 have a qualified lead-free solder reflow profile?
No-this is a press-pack device with no solderable terminations. It uses direct metal-to-metal compression bonding and requires thermal interface material (e.g., graphite foil or phase-change pad) between terminals and heatsinks. Reflow profiles are irrelevant; instead, thermal cycling qualification per JEDEC JESD22-A104E (−40 °C to +160 °C, 1000 cycles) confirms mechanical reliability under operational thermal stress.
