Twin SLIC Protector Modified TO-220
Subscriber Line Interface Circuits (SLIC) are highly susceptible to transient voltages, such
as lightning and power cross conditions. To minimize this threat, Littelfuse provides this
dual-chip, fixed-voltage SLIC protector device.
For specific design criteria, see details in Figure 3.29.
* For surge ratings, see table below.
General Notes:
· All measurements are made at an ambient temperature of 25 °C. I
PP
applies to -40 °C through +85 °C temperature range.
· I
PP
is a repetitive surge rating and is guaranteed for the life of the product.
· V
DRM
is measured at I
DRM.
· V
S
and V
F
are measured at 100 V/µs.
· Special voltage (V
S
and V
DRM
) and holding current (I
H
) requirements are available upon request.
· Off-state capacitance (C
O
) is measured across pins 1-2 or 3-2 at 1 MHz with a 2 V bias. Capacitance across pins 1-3 is
approximately half.
· Parallel capacitive loads may affect electrical parameters.
· Compliance with GR 1089 or UL 60950 power cross tests may require special design considerations. Contact the factory for further
information.
