Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLZ2V7-GS18 is determined by strict equivalence across the following critical parameters:

• Zener Voltage (Vz): 2.7 V nominal
• Power Dissipation: 500 mW maximum
• Impedance (Zzt): 100 Ohms maximum
• Forward Voltage (Vf): 1.5 V maximum at 200 mA
• Operating Temperature Range: -65°C to 175°C
• Package Type: SOD-80 Surface Mount
• Compliance Standards: ROHS3, REACH Unaffected, AEC-Q101 Automotive Grade

The substitute part TLZ2V7-GS18 meets all electrical specifications and compliance requirements. The primary distinction is the package variant designation (QuadroMELF versus MiniMELF) and product status (Obsolete versus Active), with both utilizing the SOD-80 form factor suitable for surface mount assembly.
