switches on within 250ns and withstands the 500A given by the BELLCORE 2/10µs generator.

Figures 14 and 15 give the voltage and current behavior during positive and negative 2.5kV, 2/10µs, 500A

surge tests using a LCP1511D as second stage protection device. The firing threshold values are now

adjusted to GND and to -Vbat (-48V) by the action of the second stage protection which acts as an external

voltage reference.
