Figure 1.

Repetitive peak pulse current

2.4

Parameters related to the diode line / GND (Tamb = 25°C)

Note: 1 See test circuit for VFP; RS is the protection resistor located on the line card.

2.5

Parameters related to the protection thyristor

(Tamb = 25°C unless otherwise specified)

2 See functional holding current (IH) test circuit

3 See test circuit for VDGL. The oscillations with a time duration lower than 50ns are not taken

into account

tr: rise time (µs)

tp: pulse duration (µs)

ex: Pulse waveform 10/1000 µs

tr = 10µs

tp = 1000 µs
