Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation before procurement. Confirm that the component meets RoHS compliance requirements if applicable to your design specifications. Ensure thermal management solutions align with the specified junction-to-case thermal resistance values provided in the datasheet.
Selection Notes
Select this component when high-frequency operation and low forward voltage drop are required. The 100 V rating suits applications needing moderate reverse voltage blocking. Verify that the operating temperature range accommodates the intended thermal environment and that the D2PAK package fits the available PCB space constraints.
Part Context
This part belongs to the Vishay 8TQ...S series of Schottky rectifiers. The series includes variants with different voltage ratings, such as the 8TQ080S for 80 V applications. All members share the same 8 A current rating and D2PAK surface-mount packaging configuration.
Replacement Considerations
Check for direct substitutes within the 8TQ series, specifically the 8TQ080S for lower voltage requirements. Verify pinout compatibility and thermal characteristics when considering alternative manufacturers' components.
FAQ
What is the maximum junction temperature for the 8TQ100S?
The maximum junction temperature (TJ) for the 8TQ100S is 175 °C.
How does the forward voltage drop change with temperature?
The forward voltage drop decreases as temperature increases; it is 0.72 V at 25 °C and 0.58 V at 125 °C for an 8 A current.
