2 Electrical characteristics

Table 4. On/off states Table 5. Dynamic

  1. C oss eq. is defined as a constant equivalent capacitance giving the same charging time as C oss when VDS

increases from 0 to 80% VDS. Table 6. Switching times

integrity. The integrated Zener diodes thus eliminate the need for external components. Table 7. Source-drain diode

  1. Pulse width limited by safe operating area.
  2. Pulsed: pulse duration = 300 µs, duty cycle 1.5%.
