Product details
Overview
D270N36TXPSA1 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 applications. It delivers 270 A average on-state current at TC = 100 °C, 3600 V repetitive peak reverse voltage, and withstands 4800 A surge current (10 ms, Tvj = 25 °C), operating up to 150 °C junction temperature.
For engineers reviewing the D270N36TXPSA1 datasheet, D270N36TXPSA1 pinout, D270N36TXPSA1 application, or D270N36TXPSA1 equivalent, key selection criteria include its two-sided cooling capability, low 1.54 mΩ slope resistance, 0.098 °C/W max junction-to-case thermal resistance, and validated performance under 180° sinusoidal conduction at 50 Hz.
Technical Context
This device is a single-phase, unidirectional, high-current silicon rectifier diode with pressure-contact construction and no integrated gate or control circuitry. Its on-state characteristic follows vF = A + B·iF + C·ln(iF) + D·iF² (A=0.1164, B=0.002008, C=0.2512, D=−0.04238) at Tvj = 150 °C, enabling precise forward loss modeling across 70–1000 A.
Thermal behavior is defined by analytical transient impedance ZthJC with seven RC network elements, supporting accurate thermal simulation for both anode- and cathode-sided cooling configurations. The diode exhibits 20 mA max reverse leakage at VRRM and 115×10³ A²s I²t rating for 10 ms surges at Tvj = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 3600 V - maximum repetitive reverse blocking voltage, suitable for 2.4 kV DC bus systems with 50% safety margin |
| IFAVM @ TC=100°C | 270 A - continuous average forward current with two-sided heatsink cooling at 100 °C case temperature |
| IFRMS | 640 A - RMS forward current rating, defining thermal limits under non-sinusoidal load profiles |
| IFSM (10 ms) | 4800 A - short-circuit surge current capacity, enabling robust operation during line faults in motor drives |
| vF @ 250 A | 1.36 V - forward voltage drop at rated current and max junction temperature, directly determining conduction losses |
| RthJC max | 0.098 °C/W - maximum junction-to-case thermal resistance under two-sided cooling, critical for heatsink sizing |
| Qr @ 800 A | ~100 µAs - recovered charge at high di/dt, influencing snubber design and commutation stress in phase-controlled rectifiers |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD900N36K3 | Higher 900 A IFAVM rating, 3600 V VRRM, but requires forced-air or liquid cooling due to higher RthJC (0.12 °C/W) | Targeted at lower-density, air-cooled rectifier stacks where space permits larger heatsinks | Select when system-level thermal budget allows higher RthJC and higher continuous current is required |
| D600N36T | Same 3600 V VRRM and 150 °C Tvj, but lower 600 A IFRMS and 0.11 °C/W RthJC; uses different pressure-contact geometry | Designed for legacy rectifier modules with fixed stud spacing and mechanical footprint constraints | Select only when mechanical compatibility with existing D600N36T mounting hardware is mandatory |
Compared with DD900N36K3 and D600N36T, D270N36TXPSA1 offers optimal balance of thermal performance (0.098 °C/W), compact size (270 g), and proven field reliability in two-sided cooled stacks-making it preferred for new designs prioritizing power density and thermal predictability.

FAQ
What is the recommended clamping force for D270N36TXPSA1 installation?
The datasheet specifies a mechanical clamping force range of 3.2–7.6 kN for reliable electrical contact and thermal transfer. Use calibrated torque tools and follow Infineon's mounting procedure to avoid pellet fracture or uneven pressure distribution. Exceeding 7.6 kN risks internal damage; below 3.2 kN increases contact resistance and localized heating.
Can D270N36TXPSA1 be used in single-sided cooling configurations?
Yes - the datasheet provides separate RthJC values for anode-sided (0.158 °C/W), cathode-sided (0.233 °C/W), and two-sided (0.098 °C/W) cooling. Single-sided use reduces current rating: IFAVM drops to 150 A at TC = 100 °C for anode-only cooling, requiring derating and careful thermal modeling.
Does D270N36TXPSA1 have a specified reverse recovery time (trr)?
No - as a standard (non-fast) rectifier diode, trr is not characterized. Instead, the datasheet specifies recovered charge Qr (e.g., ~100 µAs at 800 A, −di/dt = 1000 A/µs), which is the relevant parameter for snubber design and commutation loss estimation in phase-controlled applications.
Is D270N36TXPSA1 AEC-Q101 qualified?
No - this part is not AEC-Q101 qualified. It is designed and tested for industrial and traction applications per Infineon's IFBIP specification, with qualification including 1000-cycle thermal shock, 500-hour high-temperature reverse bias, and mechanical vibration testing per IEC 60068-2-6, but not automotive-specific stress profiles.
