Product details

Overview

D8320N04TVFXPSA1 from Infineon Technologies is a high-power, press-pack silicon rectifier diode designed for industrial AC/DC conversion in medium- to high-voltage thyristor-controlled rectifiers and phase-controlled DC drives. It delivers 8320 A average on-state current at TC = 56 °C, supports 400 V repetitive peak reverse voltage, and withstands 103 kA surge current (10 ms, Tvj = 25 °C), enabling use in traction converters and large motor drive systems.

For engineers reviewing the D8320N04TVFXPSA1 datasheet, D8320N04TVFXPSA1 pinout, D8320N04TVFXPSA1 application, or D8320N04TVFXPSA1 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 = 180 °C), and transient thermal impedance behavior under sinusoidal vs. rectangular conduction angles.

Technical Context

This device is a single-die, pressure-contact, stud-mounted rectifier diode with symmetrical double-sided cooling capability. Its on-state characteristic follows a four-parameter logarithmic model (A=0.8869, B=2.664e−6, C=−0.04856, D=0.004741) valid over 2.5–35 kA, and its reverse recovery charge Qr ranges from 100 µAs to 1000 µAs depending on di/dt (100–10⁴ A/µs) and IFM.

Thermal performance is defined by six analytical RC network elements for ZthJC (e.g., R₁ = 0.000034 °C/W, τ₁ = 0.000287 s), with distinct transient curves for anode-, cathode-, and two-sided cooling configurations. The maximum junction temperature is rated at 180 °C, and case temperature operation spans −25 °C to +150 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	400 V - Maximum repetitive reverse blocking voltage; defines usable DC bus voltage headroom in phase-controlled rectifiers.
IFAVM	8320 A @ TC = 56 °C - Continuous DC forward current rating; sets baseline conduction capacity for industrial drive sizing.
IFRMSM	13300 A - RMS on-state current limit; determines thermal stress under non-sinusoidal load currents (e.g., 6-pulse rectification).
IFSMM	103000 A @ 10 ms, Tvj = 25 °C - Short-circuit surge withstand; validates robustness during line faults or inverter shoot-through events.
RthJC	0.0125 °C/W (two-sided) - Junction-to-case thermal resistance; enables precise heatsink sizing for forced-air or liquid-cooled systems.
vF	0.94 V @ iF = 10 kA, Tvj = 180 °C - Forward voltage drop at full-rated current; directly impacts conduction loss and system efficiency.
Qr	100–1000 µAs - Recovered charge under 0.5–0.8×VRRM reverse bias; influences snubber design and commutation losses in line-commutated inverters.

Pinout & Package

Package: Press-pack, stud-mounted, double-sided cooled, Si pellet with pressure contact. Clamping force: 40–80 kN. Weight: ~900 g. Creepage distance: 30 mm.

Pin/Terminal	Circuit Role	Design Meaning

Key Features

Feature	Design Value
Double-sided cooling interface	Enables 0.0125 °C/W RthJC and supports >13 kW continuous conduction loss dissipation in optimized liquid-cooled assemblies.
High I²t rating	53,000 × 10³ A²s @ Tvj = 25 °C - Provides margin for short-duration overloads without junction failure in grid-tied converters.
Low slope resistance	rT = 0.024 mΩ - Ensures predictable linear voltage drop across operating current range, simplifying thermal modeling.
Controlled reverse recovery	Qr < 1000 µAs up to 10⁴ A/µs - Reduces switching-induced voltage spikes and EMI in high-di/dt applications like rolling mill drives.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current rectifier diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DD832N04K	Same VRRM (400 V) and IFAVM (8320 A), but uses ceramic housing and single-sided cooling; RthJC = 0.0232 °C/W (anode-side only).	Requires asymmetric heatsinking; unsuitable for dual-heat-path designs or compact stacked modules.	Select when mechanical integration favors ceramic encapsulation and thermal budget permits higher RthJC.
SKKT 832/04E	Lower IFAVM (6300 A), same VRRM; includes integrated temperature sensor and faster Qr (≤750 µAs); RthJC = 0.014 °C/W (two-sided).	Targeted at digitally monitored, closed-loop thermal management systems; not rated for >8.3 kA DC.	Select when real-time junction temperature feedback and tighter Qr control outweigh raw current capacity.

Compared with DD832N04K and SKKT 832/04E, D8320N04TVFXPSA1 offers superior thermal resistance and higher surge current capability, making it optimal for legacy high-power analog-controlled rectifiers where cost-per-amp and field serviceability are prioritized over smart monitoring.

FAQ

What is the recommended clamping force for D8320N04TVFXPSA1 installation?

The datasheet specifies a clamping force range of 40–80 kN. Proper application requires calibrated hydraulic tools and surface flatness ≤0.02 mm to ensure uniform pressure across the Si pellet. Under-torque risks hot-spot formation and premature failure; over-torque may fracture the ceramic insulator or deform the stud.

Can D8320N04TVFXPSA1 be used in parallel configurations?

Yes-its low slope resistance (rT = 0.024 mΩ) and matched on-state characteristics enable stable current sharing in parallel stacks. However, strict mechanical symmetry (identical heatsink contact, equal busbar inductance, and matched thermal paths) is required to avoid imbalance exceeding ±5% at full load.

Does this diode have a specified reverse recovery time (trr)?

No-trr is not specified. Instead, the datasheet provides recovered charge (Qr) and di/dt-dependent Qr curves. This reflects its design for line-commutated applications where natural zero-crossing turn-off dominates; trr is not a relevant metric for such use cases.

Is D8320N04TVFXPSA1 compliant with AEC-Q101 or automotive standards?

No-it is not AEC-Q101 qualified. The device is intended for industrial and energy infrastructure applications. Its qualification per Infineon's internal IFBIP-D standard covers extended temperature operation (−25 °C to +150 °C case), vibration resistance (50 Hz, 50 m/s²), and long-term power cycling stability-but excludes automotive-specific stress tests.
