VS-18TQ045STRL-M3

Single Diodes Overview

The VS-18TQ045STRL-M3 is a high-performance Schottky rectifier manufactured by Vishay Semiconductors. It features an 18 A average forward current rating and a maximum repetitive peak reverse voltage of 45 V. The device utilizes proprietary barrier technology to ensure low forward voltage drop and minimal reverse leakage current, even at elevated temperatures up to 175 °C junction temperature. Packaged in a D2PAK (TO-263AB) surface-mount housing with a tape-and-reel configuration, it is designed for robust mechanical strength and moisture resistance.

• High frequency operation capability with low forward voltage drop
• Guard ring structure provides enhanced ruggedness and long-term reliability

Single Diodes Applications

• Switching power supplies
• Converters
• Freewheeling diodes
• Reverse battery protection

Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging orientation and quantity. The 'TRL' suffix indicates a left-oriented tape and reel format. Confirm RoHS compliance and halogen-free status as indicated by the '-M3' designation. Ensure thermal management requirements align with the specified maximum junction temperature and thermal resistance values provided in the datasheet.

Single Diodes Selection Notes

Select this component when applications require high current density and efficient power conversion at elevated temperatures. The D2PAK package offers a balance between thermal performance and surface-mount convenience. Consider the 45 V reverse voltage rating relative to circuit peak voltages. Evaluate the low forward voltage characteristics for efficiency gains in DC-DC or AC-DC topologies where conduction losses are critical.

Single Diodes Part Context

This part belongs to the VS-18TQ... Schottky rectifier series from Vishay Semiconductors. The series includes variants with different reverse voltage ratings, such as 35 V and 40 V options. All members share the same 18 A current rating and D2PAK package style, differing primarily in their maximum working peak reverse voltage capabilities.

Single Diodes Replacement Considerations

Direct substitutes within the same series include VS-18TQ035S-M3 and VS-18TQ040S-M3 if lower voltage ratings are acceptable. For alternative manufacturers, verify equivalent current, voltage, and package dimensions. Ensure any replacement maintains similar forward voltage and reverse leakage characteristics for thermal compatibility.
