When using the test method indicated below,

the amount of Energy dissipated by the

varistor must not exceed the Load Dump

Energy value specified in the product table.

12V Network

Vi = 13.5V

Td = 100 to 350ms

Ri = 2 Ohms (Internal Resistance)

Vz - 70 to 200V

Number of Pulses = 10 Pulses

Other Load Dump Simulations can be achieved

24V Network

Vi = 27V

Td = 100 to 350ms

Ri = 2 Ohms (Internal Resistance)

Vz - 70 to 200V

Number of Pulses = 10 Pulses
