Half-Pulse width duration: 5Ons
Polarity: +ve or -ve
Phase Angle: Free non-synchronous
Peak Voltage: 1000V shall not cause malfunction (soft errors)
1500V shall not cause physical damage, but
visible malfunction is permitted
2.8.3 Electrostatic discharge
The equipment function is undamaged when subjected to a discharge (at both +ve and -ve
polarity) from a 5pF capacitor charged to a voltage specified below, limited by a 150
resistor. The discharge is applied to any user accessible points, interconnecting cables and
also the ground reference plane adjacent to the equipment.
Discharge Voltage: 6kV shall not cause malfunction (soft errors)
12kV shall not cause physical damage, but
visible malfunction is permitted
