EN/LZT 146 33 R1A (Replaces EN/LZT 137 09 R7) Ericsson Microelectronics AB, June 2000
General
NOTES
:
1)
T
P
, is defined as the maximum temperature
on the connection pins at the PB (Printed
Board) solder joint, mounted on a
5–8 dm
2
(1 dm
2
=15.5 in
2
) multi-layer PB
(>4 layers), with 20 mm (0.8 in) board-pitch
and free convection cooling. Corresponding
ambient temperature range (T
A
) at full output
power is –45…+85°C.
2)
The input voltage range 38…72 Vdc meets
the European Telecom Standard prETS
300 132-2 Nominal input voltage range in
48V and 60 Vdc power systems, –40.5…
–57.0V and –50.0...–72.0V respectively. At
input voltages exceeding 72V (abnormal
voltage) the power loss will be higher than at
normal input voltage and T
P
must be limited
to max +85°C. Absolute max continuous input
voltage is 75 Vdc. Output characteristics will
be marginally affected at input voltages
exceeding 72 V.
3)
For more information see page 5.
4)
The power modules will operate down to
V
I
36V, when V
I
decreases, but will turn on
at V
I
38V, when V
I
increases (see also
Operating information).
5)
The test is applicable for through-hole versions.

Stress in excess of Absolute Maximum Rat-
ings may cause permanent damage. Absolute
Maximum Ratings, sometimes referred to as
no destruction limits, are normally tested
with one parameter at a time exceeding the
limits of Output data or Electrical Charac-
teristics. If exposed to stress above these
limits, function and performance may de-
grade in an unspecified manner.
