1. Variation in Thermal Performance Definitions The PJD part clearly distinguishes between power dissipation and current ratings at ambient temperature (Ta) versus case temperature (Tc). Its Tc‑based data (83.3 W, 100 A) represents the maximum capability under ideal cooling. The Diotec part specifies only a single value (69 W, 100 A) without clarifying the test conditions. In practice, thermal design should be based on the more conservative 69 W figure, potentially leading to lower margin in high‑temperature or high‑power applications. 2. Absence of Switching Performance Parameters The Diotec part does not provide key dynamic parameters such as Rds(on), Qg, or Ciss. Without these data, it is impossible to properly evaluate efficiency, losses, or drive‑circuit requirements in switched‑mode power supplies or motor‑drive applications. This gap may create design blind spots, especially at higher frequencies where overheating or ringing issues can arise. 3. Implicit Conditions in Current Ratings The PJD part specifies a continuous current of 17 A at Ta, which better reflects real‑world PCB‑level thermal conditions. Diotec lists only 100 A, which typically corresponds to an ideal Tc = 25 °C scenario. In actual forced‑ or natural‑convection cooling environments, the latter may not sustain currents close to 100 A continuously, requiring reliance on measured data or more conservative derating curves.
