Frequently Asked Questions
What is the maximum peak pulse power rating?
The device has a Peak Pulse Power dissipation of 1500 W on a 10/1000 μs waveform.
How do I identify if the part is bidirectional?
Bidirectional types use the 'CA' suffix in their model number, and there should be no color band present on the device.
What are the absolute maximum operating temperatures?
The storage temperature range is -55 to +150°C, with an operating junction temperature max of +150°C.
Is this product safe for use in critical life support systems?
No; products are not authorized for use as critical components in life support devices without express written approval from Fairchild.
What flammability classification does the device hold?
The device features a UL94V-0 Flammability Classification, and is also certified by UL #E326243 and E210467.
