Notes:

1.

When ordering, specify the desired case style by adding the case designation as a suffix to the model number. Case styles for the MA44600 series

are -30,-91 and –93. To order chip form, add the suffix “-134” to the model number. The nominal chip size for the MA44600 series is 15 mils.

2.

3.

Junction capacitance is measured at a reverse voltage of 6V and a frequency of 1MHz.

4.

Transition time is measured between 20% and 80% points on the voltage recovery trace. Test conditions are +10mA and –10 volts.
