12.3 Creepage Distance

Per IEC 60664 Creepage is the shortest distance between two conductive parts or as shown in Figure 12-3 the

distance between high voltage conductive parts and grounded parts, the floating conductive part is ignored and

subtracted from the total distance.

Figure 12-3. Creepage Distance

Figure 12-3 details:

• A = Left pins (high voltage)

• B = Central pad (not internally connected, can be left floating or connected to GND)

• C = Right pins (low voltage)

• Creepage distance = a + b
