1/ For Ordering Information, Price, and Availability Contact
Factory.
2/ Screening per MIL-STD-883.
3/ For Lead Bend Options Request Document # DSB-001 (Available for Download @ ssdi-power.com).
4/ Unless otherwise specified, these specifications apply: ªV = 5V and IOUT = 5mA. Power dissipations is internally limited. How-
ever, these specifications apply for power dissipation up to 30W, IMAX = 3A.
5/ Testing is done using a pulsed low duty cycle technique.
