Overview
The Vishay 19TQ015 is a single Schottky rectifier in a TO-220AC package. It features a maximum average forward current of 19 A and a maximum repetitive peak reverse voltage of 15 V. The device operates with a junction temperature range from -55 °C to 125 °C. Key electrical characteristics include a typical forward voltage drop of 0.36 V at 19 A and 25 °C, and a maximum non-repetitive surge current of 700 A for a 5 µs sine pulse.
Feature Summary
- Optimized for OR-ing applications with ultralow forward voltage drop
- Guard ring structure provides enhanced ruggedness and long-term reliability
- High purity epoxy encapsulation ensures mechanical strength and moisture resistance
Applications
- Parallel switching power supplies
- Reverse battery protection circuits
- Redundant power subsystems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's documentation to confirm lead-free status and packaging quantity. The standard production version utilizes a tube pack containing 50 pieces. Confirm that the component meets industrial level qualification requirements before finalizing procurement specifications.
Selection Notes
Select this component when low forward voltage drop is critical for parallel power supply configurations. Ensure the thermal design accommodates the 1.50 °C/W junction-to-case thermal resistance. Verify that the operating environment remains within the specified -55 °C to 125 °C junction temperature range for reliable performance.
Part Context
This part belongs to the Vishay High Power Products Schottky rectifier series. It utilizes proprietary barrier technology designed for high-frequency operation. The device is specifically engineered to handle the thermal and electrical demands of redundant power architectures and parallel converter systems.
Replacement Considerations
Check datasheets for alternative parts offering identical 19 A current ratings and 15 V reverse voltage capabilities. Ensure replacement components support the TO-220AC package and maintain comparable forward voltage characteristics for OR-ing compatibility.
FAQ
What is the maximum non-repetitive surge current rating?
The maximum non-repetitive surge current is 700 A for a 5 µs sine pulse or 330 A for a 10 ms sine pulse.
Is this device suitable for medical life-saving applications?
No, the product specifications explicitly state it is not designed for use in medical, life-saving, or life-sustaining applications unless expressly indicated.
