Guaranteed by design but not tested. Typical parameters are representative of actual device performance but are for reference only.

Industrial grade and "E" suffix devices shall be tested to subgroups 1 and 4 unless otherwise specified.

Military grade devices ("H" suffix) shall be 100% tested to subgroups 1, 2, 3 and 4.

Subgroups 5 and 6 testing available upon request.

Device has internal shutdown feature that pulses the output with a low duty cycle during faults.

At case temperatures above 90°C, the BBF2803 requires VIN>16V to support a 5.5A load. At 125°C, 18V input is required

to support 5.5A output; 16V will support 4A output at 125°C.
