Overview
The Vishay VS-10TQ040 is a Schottky rectifier in the TO-220AC package with a maximum average forward current of 10 A and a reverse voltage rating of 40 V. It features a low forward voltage drop of 0.49 V at 10 A and 125 °C, and a maximum reverse leakage current of 15 mA at 125 °C. The device supports junction temperatures up to 175 °C, has a thermal resistance of 2.0 °C/W from junction to case, and offers a non-repetitive surge current capability of 1050 A.
Feature Summary
- Optimized for low reverse leakage current at elevated temperatures
- Proprietary barrier technology enables reliable operation up to 175 °C junction temperature
- Guard ring structure provides enhanced ruggedness and long-term reliability
Applications
- Switching power supplies
- Converters
- Freewheeling diodes
- Reverse battery protection
Procurement Notes
Verify the specific ordering suffix (PbF or -N3) to confirm lead-free and halogen-free compliance status. Ensure the selected variant matches the required environmental specifications for the target application. Cross-reference the document number 94120 for the most current electrical characteristics and mechanical dimensions before finalizing procurement.
Selection Notes
Select this component when high-frequency operation and low forward voltage drop are critical for efficiency. The TO-220AC package facilitates direct heatsinking with a thermal resistance of 2.0 °C/W. Consider the 175 °C maximum junction temperature rating for applications requiring robust thermal performance under high load conditions.
Part Context
The VS-10TQ040 belongs to the VS-10TQ... series of 10 A Schottky rectifiers manufactured by Vishay Semiconductors. This series includes variants with different reverse voltage ratings, specifically 35 V, 40 V, and 45 V. All variants share the same TO-220AC package and core electrical characteristics regarding forward voltage and thermal limits.
Replacement Considerations
Direct substitutes within the same series include VS-10TQ035PbF and VS-10TQ045PbF. These parts share identical packaging and thermal characteristics but differ in their maximum DC reverse voltage ratings of 35 V and 45 V respectively.
