 To adjust the component’s tolerances:
1. Double-click on the placed component and click the Value tab.
2. Change the following values as desired:
•
Animation Delay Factor — increase this number to slow the speed of animation of the
symbol blowing. This is not a real-time value.
•
Reverse Breakdown Voltage — set as desired.
•
Current at Breakdown Voltage — set as desired.
•
Saturation Current — the maximum current through the capacitor allowed. If this
value is exceeded during simulation, the diode blows.
•
Transit Time (sec) — used to model charge storage effects - pertains to the electrons
lifetime, alternately the hole lifetime at the p-n junction.
3. Click OK.
2.2.5 Rated Fuses
This is a resistive component that protects against power surges and current overloads.
A fuse will blow (open) if the current in the circuit goes above
I
max
, the maximum current
rating.
Note Refer to the Component Reference Guide for a more detailed discussion of fuses.
