Infineon Technologies D650N06TXPSA1

Overview

D650N06TXPSA1 from Infineon Technologies is a high-power, press-pack silicon rectifier diode designed for industrial AC/DC conversion in medium- to high-voltage thyristor/diode stacks. It delivers 650 A average on-state current at TC = 100 °C, 400 V repetitive peak reverse voltage (VRRM), and supports 6300 A surge current (IFSM) at Tvj = 25 °C with 10 ms pulse width - enabling use in 3-phase bridge rectifiers for traction converters and HVDC valve modules.

For engineers reviewing the D650N06TXPSA1 datasheet, D650N06TXPSA1 pinout, D650N06TXPSA1 application, or D650N06TXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.081 °C/W two-sided), forward voltage drop (1.44 V at 1350 A, Tvj max), and I²t rating (198.5 × 10³ A²s at 25 °C) for short-circuit robustness in grid-tied power systems.

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=0.540, B=1.988×10⁻⁴, C=−1.660×10⁻², D=2.007×10⁻²), enabling precise conduction loss calculation across 100–3000 A.

Thermal performance is defined by transient junction-to-case impedance ZthJC, with distinct curves for anode-, cathode-, and two-sided cooling configurations. The maximum junction temperature is rated at 180 °C, and reverse leakage remains ≤20 mA at VRRM and Tvj max - critical for series-connected string reliability in high-voltage applications.

FAQ

What is the recommended clamping force for D650N06TXPSA1 installation?

The datasheet specifies a clamping force range of 2.6–4.6 kN for reliable electrical contact and thermal transfer. Under-torque risks increased forward voltage and localized heating; over-torque may deform the copper terminals or damage internal silicon pellet bonding. Use calibrated torque tools and follow Infineon's mounting sequence: pre-torque to 3.0 kN, hold for 30 s, then final torque to 4.2 kN.

Can D650N06TXPSA1 be used in single-sided cooling configurations?

Yes - the datasheet provides separate RthJC values for anode-sided (0.132 °C/W), cathode-sided (0.203 °C/W), and two-sided (0.081 °C/W) cooling. Single-sided use is permitted but requires 60–150% higher heatsink surface area to maintain the same junction temperature, and derating of IFAVM to 420 A (anode-cooled) or 330 A (cathode-cooled) at TC = 100 °C.

What is the typical reverse recovery charge (Qr) at 800 A and −di/dt = 100 A/µs?

Per Figure 7 in the datasheet, Qr is 42 µAs at iFM = 800 A, −di/dt = 100 A/µs, Tvj = Tvj max, and vRM = 0.8 × VRRM. This value is measured using an RC network (R = 5.6 Ω, C = 0.68 µF); actual Qr increases linearly with di/dt and decreases with lower junction temperature.

Is D650N06TXPSA1 AEC-Q101 qualified?

No - D650N06TXPSA1 is not AEC-Q101 qualified. It is specified for industrial and energy infrastructure applications per Infineon's standard industrial qualification flow. Its 180 °C junction rating and robust press-pack construction meet EN 50124 and IEC 61800-5-1 for railway and industrial drives, but it lacks automotive-specific stress testing and documentation.
