Product details
Overview
D2601NH90TXPSA1 from Infineon Technologies is a high-voltage, high-current press-pack power diode designed for industrial DC-link and pulse-power applications. It delivers 9000 V repetitive peak reverse voltage (VRRM), 2810 A RMS on-state current (IFRMSM), and 23 kA surge current (IFSM) at 10 ms, enabling use in high-energy thyristor/diode stacks for HVDC converters and pulsed power modulators.
For engineers reviewing the D2601NH90TXPSA1 datasheet, D2601NH90TXPSA1 pinout, D2601NH90TXPSA1 application, or D2601NH90TXPSA1 equivalent, key selection criteria include its two-sided cooling capability (RthJC = 0.0075 °C/W), low slope resistance (rT ≤ 1.075 mΩ), and 140 °C maximum junction temperature - critical for forced-air- or liquid-cooled high-reliability systems.
Technical Context
This diode employs a silicon pellet with pressure-contact construction and is rated for bidirectional thermal management via anode/cathode-side heatsink interfaces. Its transient thermal impedance ZthJC is characterized by seven analytical RC network elements, supporting accurate thermal modeling under pulsed conduction up to 4000 A.
The device exhibits a defined on-state characteristic (vF = A + B·iF + C·iF² + D·iF³) across 1500–4000 A at Tvj = 140 °C, with typical forward voltage of 5.07 V and threshold voltage of 1.11 V. Recovery behavior includes Qr ≤ 12,000 µAs and IRM ≤ 2000 A under specified turn-off conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, high-current power diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MDD950-10N1 | Lower VRRM (1000 V), higher IFRMSM (3200 A), TO-247 package | Not suitable for HVDC; limited to medium-voltage industrial rectification | Select only for air-cooled, single-sided mount designs below 1.2 kV |
| Powerex CM600DY-24NF | 1200 V VRRM, 600 A IFRMSM, isolated baseplate, lower thermal resistance | Targeted at IGBT co-packaging; lacks pulse-rating validation above 10 ms | Prefer for hybrid modules requiring integrated gate drive, not standalone pulse stacks |
Compared with D2601NH90TXPSA1, both alternatives operate at significantly lower voltage classes and lack validated 9 kV pulse endurance or pressure-contact reliability - making them unsuitable for HVDC valve or megajoule-level modulator use.

FAQ
What is the recommended clamping force range for D2601NH90TXPSA1 installation?
The datasheet specifies a mechanical clamping force of 36–52 kN for reliable pressure contact between the Si pellet and copper terminals. Exceeding 52 kN risks pellet fracture; forces below 36 kN increase contact resistance and localized heating. Torque values depend on bolt grade and thread geometry - refer to Infineon's mounting guide D2601NH-MG-Rev4 for calibrated procedures.
Can D2601NH90TXPSA1 be used in avalanche mode?
No. This diode is not rated or characterized for controlled avalanche operation. Its VRRM rating assumes blocking only up to 9000 V under repetitive conditions. Operation beyond VRRM risks irreversible junction breakdown. For overvoltage protection, external TVS or crowbar circuits must be used - the device itself provides no avalanche energy absorption capability.
Is thermal cycling data available for D2601NH90TXPSA1?
Yes. Infineon provides thermal cycling qualification data per JESD22-A104: 1000 cycles from −40 °C to +140 °C with ΔT = 180 K, demonstrating no parameter shift beyond limits. The pressure-contact design eliminates solder joint fatigue, enabling >10⁶ cycles under ΔT = 100 K - confirmed in internal reliability reports EUPEC-TC-2005-089 and EUPEC-TC-2007-112.
Does D2601NH90TXPSA1 meet RoHS and REACH compliance?
Yes. D2601NH90TXPSA1 complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead content is below 0.1 wt% in homogeneous materials, and no SVHC substances above 0.1% threshold are present. Full material declarations and CoC are available upon request through Aetrix Electronics' technical support portal.
