8TQ080

Overview

The Vishay VS-8TQ080-N3 is a single Schottky rectifier diode constructed from silicon. It features an 8 A average forward current rating and an 80 V repetitive peak reverse voltage capability. The device exhibits a typical forward voltage of 580 mV at rated current, with a maximum reverse leakage current of 7 mA. It supports a high non-repetitive surge current of 850 A and operates within a junction temperature range of -55 °C to +175 °C. The component is housed in a TO-220AC package.

Feature Summary

• Utilizes proprietary barrier technology for low forward voltage drop and high frequency operation
• Features high purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance
• Incorporates guard ring structure for improved ruggedness and long-term reliability

Applications

• Switching power supplies
• DC-DC converters
• Freewheeling diodes
• Reverse battery protection circuits

Procurement Notes

Verify the specific suffix against official documentation, as variations may indicate different packaging or environmental compliance levels. Confirm availability status directly with the manufacturer, as distribution channels may list obsolete or discontinued stock. Ensure the procurement source provides valid RoHS compliance certificates matching the specific part revision. Cross-reference the ordering number with the latest Vishay datasheet to confirm pinout and thermal characteristics before finalizing orders.

Selection Notes

Select this component for designs requiring efficient rectification with minimal forward voltage loss at moderate currents. The wide operating temperature range makes it suitable for industrial environments where thermal management is critical. Consider the TO-220AC package for through-hole mounting applications requiring robust mechanical stability. Evaluate the 850 A surge rating against potential inrush currents in the target circuit to ensure adequate safety margins during startup conditions.

Part Context

This component belongs to Vishay's high-power Schottky rectifier series, designed specifically for applications demanding high efficiency and reliability. The product line emphasizes low reverse leakage at elevated temperatures, distinguishing it from standard silicon rectifiers. It serves as a discrete solution for power conversion stages where fast switching speeds and reduced heat generation are primary design constraints.

Replacement Considerations

Officially documented substitutes include the VS-8TQ080-M3 variant. Verify electrical equivalence and physical dimensions before substitution.
