Overview
The Vishay 8TQ080S is an 8 A Schottky rectifier in a D2PAK package. It features a maximum DC reverse voltage of 80 V and operates up to 175 °C junction temperature. Key electrical parameters include a forward voltage drop of 0.58 V at 8 A and 125 °C, and a peak surge current rating of 850 A. The device utilizes proprietary barrier technology for low reverse leakage and high frequency operation.
Feature Summary
- Optimized for low reverse leakage at elevated temperatures
- Designed and qualified for automotive Q101 level reliability
- Features guard ring structure for enhanced ruggedness
- Utilizes high purity epoxy encapsulation for mechanical strength
Applications
- Switching power supplies

Procurement Notes
Verify the specific ordering suffix to confirm packaging orientation and lead-free status. Standard production units are available in tubes, while tape and reel options exist in left or right orientations. Confirm that the component meets RoHS directives and halogen-free requirements before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring high-frequency operation and low forward voltage drop. Ensure thermal management allows for case temperatures within limits defined by the duty cycle. Verify that the 80 V reverse voltage rating accommodates system transients and that the D2PAK footprint matches the PCB layout constraints.
Part Context
This part belongs to the 8TQ...S series of Schottky rectifiers from Vishay High Power Products. The series includes variants with different voltage ratings, such as the 8TQ100S. These devices are designed for general-purpose high-power applications requiring robust performance under varying thermal conditions.
Replacement Considerations
The 8TQ100S serves as a direct substitute offering identical current and package specifications with a higher 100 V reverse voltage rating. Ensure the application voltage does not exceed the original 80 V limit if substituting with lower-rated alternatives.
FAQ
What is the maximum non-repetitive surge current rating?
The maximum peak one-cycle non-repetitive surge current (IFSM) is 850 A for a 5 µs sine pulse.
Is the device suitable for automotive applications?
Yes, the 8TQ...S series is designed and qualified for Q101 level automotive reliability standards.
