Infineon Technologies D8320N06TVFXPSA1

Overview

D8320N06TVFXPSA1 from Infineon Technologies is a high-power, press-pack silicon rectifier diode designed for industrial AC/DC conversion in medium-frequency thyristor-controlled rectifiers and phase-controlled DC drives. It delivers 8320 A average on-state current at TC = 56 °C, supports 600 V repetitive peak reverse voltage, and handles 103 kA surge current (10 ms, Tvj = 25 °C), enabling use in high-current traction converters and welding power supplies.

For engineers reviewing the D8320N06TVFXPSA1 datasheet, D8320N06TVFXPSA1 pinout, D8320N06TVFXPSA1 application, or D8320N06TVFXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.0125 °C/W two-sided), on-state voltage (0.94 V at 10 kA, Tvj max), and transient thermal impedance behavior under sinusoidal vs. rectangular conduction angles.

Technical Context

This device operates as a unidirectional, non-controlled power rectifier with a planar-diffused silicon die mounted in a double-sided cooled, pressure-contact package. Its on-state characteristic follows a four-parameter logarithmic model (A=0.8869, B=2.664E-06, C=-0.04856, D=0.004741) valid between 2500 A and 35,000 A at Tvj max.

Thermal performance is defined by dual-path junction-to-case resistance depending on cooling configuration: 0.0125 °C/W (two-sided), 0.0232 °C/W (anode-side only), and 0.0250 °C/W (cathode-side only), with transient ZthJC governed by seven analytical RC network elements per cooling mode.

FAQ

What is the recommended clamping force for D8320N06TVFXPSA1 installation?

The datasheet specifies a mechanical clamping force range of 40–80 kN for reliable pressure contact between the Si pellet and both heatsink surfaces. Applying 60 kN ensures optimal thermal resistance (0.0125 °C/W) while avoiding die fracture. Torque must be applied evenly using calibrated tools and follow the two-stage tightening sequence defined in Infineon Application Note AN2007-03.

Can D8320N06TVFXPSA1 be paralleled with other rectifiers for higher current capacity?

Yes, but only with strict matching: units must be from the same wafer lot, have identical vF at 10 kA (±0.01 V), and share a common, symmetrically machined heatsink. Parallel operation requires individual current-sharing inductors (≥1 µH) and active thermal monitoring, as slope resistance mismatch (rT = 0.024 mΩ) can cause >15% current imbalance above 5 kA.

What is the maximum allowable case temperature under 100% DC load?

At full-rated IFAVM = 8320 A, the maximum allowable case temperature is 56 °C for continuous operation, as defined by the derating curve on page 6 of the datasheet. Exceeding this value reduces lifetime exponentially; for operation up to 150 °C case temperature, current must be reduced to ≤2200 A per the TC = f(IFAV) graph under two-sided cooling.

Does D8320N06TVFXPSA1 meet AEC-Q101 qualification standards?

No - this device is qualified per Infineon's industrial standard IFBIP, not AEC-Q101. It lacks automotive-specific stress testing (e.g., temperature cycling, humidity bias). While used in some rail traction systems, it is not approved for passenger vehicle powertrain applications. For automotive-grade equivalents, consider Infineon's AEC-Q101-certified SKx series with derated ratings.
