Frequently Asked Questions
What is the safe operating junction temperature range?
The Operating Junction Temperature range is specified as -65 to +150 °C.
Are these Schottky Rectifiers suitable for life support systems?
No, they are not authorized for use as critical components in life support devices without explicit written approval from Fairchild Semiconductor Corporation.
What is the maximum non-repetitive peak forward surge current rating?
The datasheet lists the Non-repetitive Peak Forward Surge Current (FSM), which reaches 200 A at 8.3 ms for certain models.
How is power dissipation related to ambient temperature?
Power Dissipation (P) is listed as 3.0 W, and the data features a Forward Current Derating Curve to guide usage across varying temperatures.
