4.6 Typical Power Block Device Characteristics

The typical power block system characteristic curves (Figure 4-1 through Figure 4-6) are based on measurements made on a PCB design with dimensions of 4in (W) × 3.5in (L) × 0.062in (H) and 6 copper layers of 2oz copper thickness. See Section 5 section for detailed explanation. TJ = 125°C, unless stated otherwise.
