1. Breakdown Voltage (Vdss): 650V (FCP) vs. 600V (IPP). The IPP device offers 50V less voltage margin. In applications prone to voltage spikes or transient overvoltages (e.g., switching power supplies), this increases the risk of breakdown. It is critical to ensure the peak operating voltage remains below 600V with an adequate safety margin. 2. Gate Charge (Qg) & Input Capacitance (Ciss): FCP's Qg is 61 nC, while IPP's is 80 nC (both @10V), and the IPP has a higher Ciss. This results in slower switching speed and higher gate drive losses for the IPP. In high-speed switching applications (e.g., high-frequency PWM), efficiency may degrade, necessitating a stronger gate drive current or adjusted dead-time settings. 3. Maximum Gate-Source Voltage (Vgs(max)): ±30V (FCP) vs. ±20V (IPP). The IPP is more sensitive to gate overvoltage and is susceptible to damage in noisy environments or with fluctuating drive voltages. The gate drive circuit output must be strictly limited to within ±20V, or additional clamping protection should be added. 4. Certification & Reliability: The IPP is AEC-Q101 automotive-grade compliant, while the FCP does not specify such certification. The IPP is suitable for high-reliability scenarios (e.g., automotive electronics), featuring more stringent quality control and temperature cycling tests, albeit at potentially higher cost. For industrial or consumer applications, the FCP may offer a more economical solution. 5. On-Resistance (Rds(on)) Test Condition Discrepancy: FCP is tested at 15A, IPP at 18A. Although their nominal values are similar (99mΩ vs. 105mΩ), this indicates different non-linear responses of their conduction characteristics under varying load currents. Conduction losses must be verified at the actual operating current point to avoid thermal design errors.
