Notes:
1. When ordering, specify the desired case style by adding the case des-
ignation as a suffix to the model number. Case styles for the MA44600
series are 30, 91 and 93. To order in chip form, add the suffix “134” to
the model number. The nominal chip size for the MA44600 series is
15 mils.

2. Reverse voltage (V_R) is measured at a reverse bias current of 10 µA.
3. Junction capacitance is measured at a reverse voltage of 6 volts and a
frequency of 1 MHz.
4. Transition time is measured between 20% and 80% points on the volt-
age recovery trace. Test conditions are +10 mA and -10 volts.
