he maximum short-circuit duration must be limited to the maximum value given in the semiconductor data sheet. Figure 14 illustrates how diodes DVCE1 and DVCE2 may be used to measure switch desaturation. For insulation, two diodes in SMD packages are used (STTH212U for example). RRES connected to VISO guarantees current flow through the diodes when the semiconductor is in the on-state. When the switch desaturates, CRES starts to be charged through RRES. In this configuration the response time is controlled by RRES and CRES. In this application example CRES = 33 pF and RRES = 62 kW; if desaturation is too sensitive or the short-circuit duration too long, both CRES and RRES can be adjusted. Figure 15 shows the recommended PCB layout and corresponds to the schematic in Figure 13. The PCB is a two layer design. It is important to ensure that PCB traces do not cover the area below the desaturation resistors or diodes DVCE1 and DVCE2. This is a critical design requirement to avoid coupling capacitance w
