Product details
Overview
D3501N36TXPSA1 from Infineon Technologies is a high-power, hermetically sealed ceramic press-pack rectifier diode designed for bidirectional forced-cooled DC applications. It delivers 3470 A average forward current at TC = 100 °C, withstands 4200 V repetitive peak reverse voltage, and handles 63 kA surge current (10 ms, Tvj = 25 °C), serving in industrial drive rectification and crowbar protection circuits.
For engineers reviewing the D3501N36TXPSA1 datasheet, D3501N36TXPSA1 pinout, D3501N36TXPSA1 application, or D3501N36TXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (8.5 K/kW, two-sided cooling), threshold voltage (0.734 V), slope resistance (0.134 mΩ), clamping force range (36–52 kN), and ceramic package mechanical robustness for high-reliability power conversion systems.
Technical Context
This diode employs a silicon pellet with pressure-contact metallization and is engineered for full 50/60 Hz blocking capability across –40 °C to +160 °C junction temperature. Its low on-state voltage (1.27 V max at 4000 A) and minimal dynamic losses are enabled by a low rT (0.134 mΩ) and controlled VT0 (0.734 V).
The device supports two-sided, anode-sided, or cathode-sided cooling configurations, with transient thermal impedance ZthJC characterized analytically for precise thermal modeling. Reverse recovery behavior is specified under standardized test conditions (VR = 100 V / 1000 V, IFM = 1000 A, –di/dt = 10 A/µs), yielding Qr ≤ 10 mAs and IRM ≤ 300 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 4200 V - maximum repetitive reverse voltage the diode blocks reliably in AC line-frequency applications |
| IFAVM | 3470 A at TC = 100 °C - continuous DC forward current rating under standard two-sided heatsink cooling |
| IFSM | 63000 A (10 ms, Tvj = 25 °C) - short-circuit surge current capacity without destructive failure |
| VT0 & rT | 0.734 V / 0.134 mΩ - linearized on-state model parameters defining conduction loss at high current |
| RthJC | 8.5 K/kW (two-sided) - thermal resistance from junction to case, critical for heatsink sizing and derating |
| Clamping Force | 36–52 kN - required mechanical compression to ensure low contact resistance and thermal interface integrity |
| Qr | ≤10 mAs (VR = 1000 V) - recovered charge during turn-off, directly impacting snubber design and switching losses |
Pinout & Package
Hermetically sealed ceramic press-pack housing with dual-side metal contacts: Anode (terminal 1) and Cathode (terminal 2). No leaded or molded package; requires external clamping assembly and thermal interface management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Forward current entry point | High-current input terminal; must be compressed with ≥36 kN to maintain low RthCH and prevent hot-spotting |
| 2 (Cathode) | Forward current exit point | High-current output terminal; symmetrically rated with Anode for bidirectional thermal path design |
Key Features
| Feature | Design Value |
|---|---|
| Full 50/60 Hz blocking | Stable reverse blocking over –40 °C to +160 °C junction temperature, eliminating derating concerns in grid-tied systems |
| High DC blocking stability | Guaranteed VRRM retention under sustained DC bias and thermal cycling, critical for HVDC link protection |
| High surge current capability | 63 kA IFSM enables reliable operation during motor-start transients and fault clearing in drive inverters |
| Hermetically sealed ceramic package | Eliminates moisture ingress and partial discharge risk in humid or contaminated industrial environments |
| High case non-rupture current | Withstands mechanical stress from repeated high di/dt events without housing fracture or contact separation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-power rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MDD3501N36TXPSA1 | Identical electrical specs (VRRM=4200 V, IFAVM=3470 A), same clamping force range, but uses TO-247-3L-compatible baseplate geometry | Suitable for retrofit into legacy IXYS-based designs with different mounting hole pattern | Select when mechanical footprint compatibility with prior IXYS modules is required |
| ABB 5SDD35H4203 | Higher VRRM (4200 V), lower IFAVM (3200 A at TC=100°C), RthJC = 9.5 K/kW (two-sided), ceramic-metal seal instead of all-ceramic | Better suited for single-sided cooled installations where anode-side heat extraction dominates | Prefer when system layout restricts cathode-side heatsinking or demands ABB's certified grid-code compliance documentation |
Compared with MDD3501N36TXPSA1 and 5SDD35H4203, D3501N36TXPSA1 offers the lowest RthJC (8.5 K/kW) and highest IFAVM (3470 A) among equivalents, making it optimal for thermally constrained, bidirectionally cooled high-power rectifiers demanding maximum current density.

FAQ
What is the recommended clamping force range for D3501N36TXPSA1?
The device requires a mechanical clamping force between 36 kN and 52 kN to ensure optimal thermal contact and low interfacial resistance. Under-clamping increases RthCH and risks localized overheating; over-clamping may deform the ceramic housing or damage internal Si-pellet metallization. Force must be applied uniformly across both terminals using calibrated torque-controlled fixtures.
Can D3501N36TXPSA1 be used with single-sided cooling?
Yes - D3501N36TXPSA1 supports anode-sided, cathode-sided, or two-sided cooling. For single-sided use, RthJC rises to 14.9 K/kW (anode) or 19.8 K/kW (cathode), requiring derating of IFAVM by ~25% at TC = 100 °C. Thermal simulation using provided ZthJC analytical data is mandatory to confirm safe operation.
What is the maximum junction temperature and how does it affect lifetime?
The absolute maximum junction temperature (Tvj max) is 160 °C. Operating continuously above 140 °C accelerates degradation of the pressure-contact interface and ceramic seal, reducing mean time to failure. Lifetime follows Arrhenius kinetics: every 10 °C reduction below 160 °C approximately doubles operational life under constant current stress.
Is D3501N36TXPSA1 RoHS compliant and halogen-free?
Yes - D3501N36TXPSA1 complies with EU RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The ceramic housing, molybdenum interconnects, and silver-plated copper terminals contain no restricted substances above threshold limits. Certificate of Compliance is available upon request with batch traceability.
