TRIPOLAR OVERVOLTAGE
PROTECTION FOR TELECOM LINE
FEATURES
BIDIRECTIONAL CROWBAR PROTECTION
BETWEEN TIP AND GND, RING AND GND
AND BETWEEN TIP AND RING.

IPP = 30A for 10/1000µs surge.
HOLDING CURRENT :
IH = 150mA.
AVAILABLEIN SO8 PACKAGES.
LOW DYNAMIC BREAKOVER VOLTAGE.
DESCRIPTION
Dedicated to telecommunication equipment
protection, these devices provide a triple
bidirectional protection function.
They ensure the same protection capability with
the same breakdown voltage both in longitudinal
mode and transversal mode.
A particular attention has been given to the internal
wire bonding. The ”4-point” configuration ensures
a reliable protection, eliminating overvoltages
introduced by the parasitic inductances of the
wiring (Ldi/dt), especially for very fast transient
overvoltages.
Dynamic characteristics have been defined for
several types of surges, in order to meet the SLIC
maximum ratings.
