Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLZ5V6-GS08 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Zener voltage: 5.6 V nominal
• Maximum power dissipation: 500 mW
• Maximum impedance: 13 Ohms
• Forward voltage: 1.5 V maximum at 200 mA
• Operating temperature range: -65°C to 175°C
• Surface mount configuration
• SOD-80 package family compatibility

The TLZ5V6-GS08 qualifies as a direct substitute based on identical electrical specifications across all parameters listed above. The primary distinction between the main part and its substitute is packaging format (QuadroMELF versus MiniMELF) and product status (obsolete versus active).

Parameter Comparison

Engineering Selection Recommendations

The TLZ5V6-GS08 is the direct electrical equivalent for the obsolete VLZ5V6-GS08. Both components maintain identical electrical performance across all specified parameters, including zener voltage, power rating, impedance, and forward voltage characteristics. Both parts carry ROHS3 compliance, AEC-Q101 automotive qualification (where applicable), and MSL Level 1 moisture sensitivity rating.

The primary consideration for selection is packaging format compatibility. The VLZ5V6-GS08 uses the QuadroMELF variant of SOD-80, while the TLZ5V6-GS08 uses the MiniMELF variant. Both are SOD-80 family packages and share identical electrical footprints for surface mount PCB assembly. The TLZ5V6-GS08 is currently in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the TLZ5V6-GS08 directly replace the VLZ5V6-GS08 in existing designs?

A: Yes. The TLZ5V6-GS08 provides identical electrical performance across all specified parameters. Both components are SOD-80 surface mount packages with matching zener voltage (5.6 V), power rating (500 mW), impedance (13 Ohms maximum), and operating temperature range (-65°C to 175°C). PCB footprints are compatible.

Q: What is the difference between QuadroMELF and MiniMELF packaging?

A: Both QuadroMELF and MiniMELF are variants within the SOD-80 package family. The distinction relates to physical form factor and lead configuration, but electrical performance and PCB mounting compatibility remain identical for the specified parameters.

Q: Are there compliance or certification differences between these parts?

A: No. Both the VLZ5V6-GS08 and TLZ5V6-GS08 carry ROHS3 compliance, MSL Level 1 rating, and identical REACH and ECCN classifications. The TLZ5V6-GS08 maintains active product status, ensuring continued compliance support.

Q: Why is the VLZ5V6-GS08 marked as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The TLZ5V6-GS08 represents the active equivalent within Vishay's current product portfolio, offering identical electrical specifications with ongoing production and supply availability.

Q: What inventory status should be considered for procurement?

A: The TLZ5V6-GS08 is available in active production with 812 pieces in new original stock. The VLZ5V6-GS08 remains available with 684 pieces in stock but is classified as obsolete. For new designs and long-term supply assurance, the TLZ5V6-GS08 is the recommended selection.
