Frequently Asked Questions
What is the maximum non-repetitive peak forward surge current?
The Peak Forward Surge Current ($I_{FSM}$) is listed as 50 A for an 8.3 ms single half-sine wave.
How is the thermal resistance calculated when mounting on a PCB?
The datasheet lists the Thermal Resistance, Junction to Ambient ($R_{ heta JA}$), which is 75 °C/W when mounted on FR-4 PCB.
What are these product electrical ratings considered?
They are stated as absolute maximum ratings; exceeding them may impair serviceability of the semiconductor device.
In what kinds of power conversion systems can these rectifiers be used?
They are ideal for low voltage, high frequency inverters, free wheeling circuits, and polarity SMB/DO-214AA protection applications.
