120 A for 200 µs
Max Total Module Current: 6 channels each carrying
30 A ‡
Initial On Path Resistance:
Leakage Current (at ±40 V):
6 mΩ at 25 ˚C typical
<1 µA at 25 ˚C and switch
cold, <5 mA at max
temperature immediately
after switch has carried
maximum current for
>10 minutes.
Rise/Fall Time:
Operate Time:
Max Operating Speed at
nominal load:
40 µs/140 µs (typical)
250 µs
60 operations/sec
Expected Life (operations): Indefinite when used
within ratings
* For full voltage rating, signal sources to be switched
must be fully isolated from mains supply and safety earth.
† Differential voltage between channels must not exceed
rated voltage, additional caution should be used when
applying AC voltages as multiple asynchronous supplies
can create high differential voltages between channels.
‡ The capacity of the module to carry 30 A on all channels
is chassis dependent and dependent on the number of high
power modules fitted to the chassis. Specification reflects
test conditions in a Pickering PXI chassis. Refer to supplier
for chassis cooling capacity, restrict average RMS current
over 5 minute period to 25 A per channel for chassis
meeting the minimum PXI recommendations.
