6CWQ06FNTR

Overview

The Vishay 6CWQ06FNTR is a surface-mount Schottky rectifier featuring a center tap configuration in a D-PAK (TO-252AA) package. It provides a maximum average forward current of 7 A and a repetitive peak reverse voltage of 60 V. The device exhibits a low forward voltage drop, specified at 0.61 V per leg at 3 A and 0.76 V at 6 A. Key electrical characteristics include a maximum reverse leakage current of 2 mA at 25 °C and a non-repetitive surge current capability of 490 A. The junction temperature range spans from -40 °C to +150 °C.

Procurement Notes

Verify the specific suffix against the ordering information table to confirm packaging orientation. The 'TR' suffix indicates standard tape and reel, while 'TRL' denotes left-oriented and 'TRR' right-oriented reels. Confirm lead-free status if required by assembly specifications. Ensure the component meets the RoHS Directive 2002/95/EC requirements for your manufacturing process.

Selection Notes

Select this component when a compact surface-mount solution with high current density is required. The center tap design allows for split current paths, reducing thermal stress on individual legs. Evaluate the thermal resistance of 4.70 °C/W per leg to ensure adequate heat dissipation within the target operating environment. Consider the low junction capacitance for high-frequency switching applications where rapid recovery is necessary.
