Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLZ6V8-GS18 is determined by equivalence across the following critical parameters:

• Zener Voltage: 6.8 V nominal specification
• Power Dissipation: 500 mW maximum rating
• Impedance: 8 Ohms maximum
• Forward Voltage: 1.5 V maximum at 200 mA
• Operating Temperature Range: -65°C to 175°C
• Surface Mount Configuration: SOD-80 package family
• Regulatory Compliance: ROHS3 and AEC-Q101 qualification

The TLZ6V8-GS18 meets all electrical and thermal specifications required for direct substitution. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical core electrical characteristics. The primary distinction is packaging format: VLZ6V8-GS18 uses QuadroMELF configuration while TLZ6V8-GS18 uses MiniMELF configuration, both within the SOD-80 package family. The substitute part carries active product status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The TLZ6V8-GS18 is the direct electrical equivalent for the obsolete VLZ6V8-GS18. Both components satisfy identical electrical performance requirements and maintain AEC-Q101 automotive qualification. The substitute part offers the advantage of active product status, ensuring availability for new designs and ongoing production requirements.

Selection between QuadroMELF and MiniMELF package variants depends on PCB layout constraints and thermal management requirements. Both variants are SOD-80 package family members and maintain identical electrical specifications. The MiniMELF configuration (TLZ6V8-GS18) provides a smaller footprint suitable for space-constrained applications, while QuadroMELF (VLZ6V8-GS18) offers enhanced thermal dissipation characteristics.

ROHS3 compliance and MSL 1 rating confirm suitability for standard manufacturing processes without special handling requirements. Both parts are REACH unaffected and carry EAR99 export classification.
