1. Voltage and Current Ratings: The IPAW60R180P7SXKSA1 features a Vds of 650V, providing a higher voltage margin compared to the 600V rating of the ST part, which can enhance system reliability. However, its continuous drain current (Id) rating of 18A is lower than the ST device's 20A. In applications operating near the original design's current limit, this may lead to increased junction temperature. 2. On-Resistance and Test Conditions: The nominal Rds(on) of the IPAW60R180P7SXKSA1 (180mΩ) is higher than that of the ST part (163mΩ). Crucially, note that its specified test current is 5.6A, versus 10A for the ST device. This indicates its conduction characteristics may not be optimized for higher currents. Actual conduction losses in the application must be re-evaluated based on the operating current. 3. Gate Charge and Switching Performance: The total gate charge (Qg) of the IPAW60R180P7SXKSA1 (25nC) is significantly lower—by approximately 24%—than the ST device's 33nC. This results in faster switching speed, lower switching losses, and reduced gate drive current requirements, which is beneficial for increasing frequency and efficiency. However, attention must be paid to mitigating potential voltage ringing and EMI issues caused by excessively fast switching transitions. 4. Input Capacitance: The IPAW60R180P7SXKSA1 has a lower input capacitance (Ciss). Furthermore, it is specified at a higher test voltage (400V), which further suggests its Miller capacitance (Cgd) under high-voltage conditions may be smaller. This characteristic can improve switching transient stability and reduce the risk of spurious turn-on. 5. Technology and Cost: The IPAW60R180P7SXKSA1 utilizes Infineon's CoolMOS™ P7 technology, which is focused on minimizing switching losses. In contrast, the ST part employs MDmesh™ M2-EP technology, which aims for a balance between conduction and switching losses. The former carries a price premium of approximately 34%, representing the cost for its performance advantages.
