VS-20TQ035STRRPBF

Single Diodes Overview

The VS-20TQ035STRRPBF is a Schottky rectifier from Vishay High Power Products, rated for a maximum average forward current of 20 A and a maximum DC reverse voltage of 35 V. It utilizes a D2PAK surface-mount package with a base cathode configuration. The device operates within a junction temperature range of -55 °C to 150 °C and features a typical forward voltage drop of 0.57 V at 20 A and 25 °C. It supports non-repetitive surge currents up to 1800 A and includes a guard ring structure for enhanced ruggedness.

Single Diodes Feature Summary

• Optimized proprietary barrier technology enables reliable operation at elevated junction temperatures up to 150 °C.
• Guard ring structure provides enhanced ruggedness and long-term reliability under demanding conditions.
• High purity epoxy encapsulation ensures mechanical strength and moisture resistance.
• Compliant with RoHS directive 2002/95/EC and IEC 61249-2-21 halogen-free definitions.

Single Diodes Applications

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

Single Diodes Procurement Notes

Verify the specific ordering suffix STRR against official documentation to confirm right-oriented tape and reel packaging. Ensure the PbF designation aligns with lead-free requirements. Confirm that the 35 V rating matches the circuit's peak reverse voltage needs. Validate thermal management strategies for the D2PAK package to maintain junction temperatures within the specified 150 °C limit during continuous operation.

Single Diodes Selection Notes

Select this component when low forward voltage drop is critical for efficiency in high-frequency applications. The D2PAK package offers a balance between current handling capability and surface-mount convenience. Consider the 150 °C operating temperature for environments requiring higher thermal tolerance than standard silicon devices. Verify compatibility with automated pick-and-place equipment due to the tape and reel format.

Single Diodes Part Context

This part belongs to the VS-20TQ...SPbF series of Schottky rectifiers, which are optimized for very low forward voltage drop with moderate leakage current. The series includes variants with different reverse voltage ratings (35 V, 40 V, 45 V) but shares the same 20 A current rating and D2PAK package outline. The 'Q' in the model number denotes the Schottky 'Q' series technology.
