Infineon Technologies D2520N22TVFXPSA1

Overview

D2520N22TVFXPSA1 from Infineon Technologies is a high-power, press-pack, dual-plate silicon rectifier diode designed for industrial AC/DC conversion in medium-voltage traction and grid applications. It delivers 2520 A average on-state current at TC = 100 °C, 2200 V repetitive peak reverse voltage, and withstands 41 kA surge current (10 ms, Tvj = 25 °C), operating up to 175 °C junction temperature.

For engineers reviewing the D2520N22TVFXPSA1 datasheet, D2520N22TVFXPSA1 pinout, D2520N22TVFXPSA1 application, or D2520N22TVFXPSA1 equivalent, key selection criteria include thermal resistance (RthJC ≤ 0.022 °C/W two-sided), low forward voltage (1.75 V @ 10.2 kA), clamping force range (15–24 kN), and I²t rating (8405 × 10³ A²s).

Technical Context

This device is a symmetric, double-sided cooled, pressure-contact rectifier with no integrated gate or control circuitry - it operates as a passive, uncontrolled power switching element in line-commutated converters. Its conduction behavior follows a defined on-state characteristic (vF = A + B·iF + C·ln(iF) + D·iF²) with validated parameters at Tvj max.

Thermal performance is defined across three cooling configurations: anode-, cathode-, and two-sided. Transient thermal impedance ZthJC is analytically modeled using seven RC network elements, enabling accurate loss and temperature prediction under non-sinusoidal, pulsed, or overload conditions.

FAQ

What is the required clamping force for D2520N22TVFXPSA1?

The device requires a mechanical clamping force between 15 kN and 24 kN across its anode and cathode plates to ensure low contact resistance and reliable thermal transfer. Force below 15 kN risks hot-spot formation and premature failure; above 24 kN may deform ceramic housing or damage internal Si pellet bonding. Use calibrated torque-controlled fixtures and verify with strain gauges during assembly.

Can D2520N22TVFXPSA1 be used in single-sided cooling configurations?

Yes - it supports anode-only or cathode-only cooling, but thermal resistance increases significantly: RthJC rises to 0.0397 °C/W (anode-side) or 0.0453 °C/W (cathode-side). Derating of IFAVM to ≤1850 A at TC = 100 °C is mandatory. Dual-sided cooling is strongly recommended to achieve full rated current and lifetime reliability.

What is the typical reverse recovery charge Qr at 2000 A and di/dt = 1000 A/µs?

At Tvj = 175 °C, VR = 0.5 × VRRM, and di/dt = 1000 A/µs, Qr is 1250 µAs (1.25 × 10⁻³ As), as confirmed by Figure 7 in the official datasheet. This value is critical for snubber design and EMI estimation in phase-controlled rectifier bridges operating at 50/60 Hz.

Does D2520N22TVFXPSA1 comply with AEC-Q101 or automotive standards?

No - this device is not qualified to AEC-Q101. It is designed and tested for industrial and traction applications per IEC 60747-2 and EN 50124-1. Its qualification scope covers vibration resistance (50 Hz, 50 m/s²), storage temperature (−40 to +175 °C), and surge endurance - but excludes automotive-specific stress tests like temperature cycling or board-level reliability.
