Verify that the circuit driving the gate will meet the VGS(th) from the Electrical Characteristics table. 5. Using the max output current calculated in step 1, check Figure 7 to insure that the range of Zener clamp voltage over temperature will satisfy all system & EMI requirements. 6. Use IGSS and IDSS from the Electrical Characteristics table to insure that “OFF” state leakage over temperature and voltage extremes does not violate any system requirements. 7. Review circuit operation and insure none of the device max ratings are being exceeded. 1. Determine the maximum inductive load current (at max VCC, min coil resistance & usually minimum temperature) that the NUD3105 will have to drive and make sure it is less than the max rated current. 2. For pulsed operation, use the Transient Thermal Response of Figure 11 and the instructions with it to determine the maximum limit on transistor power dissipation for the desired duty cycle and temperature range. 3. Use Figures 10 and 11 with the SOA notes to insure that instantaneous operation does not push the device beyond the limits of the SOA plot.
