Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLZ24-GS08 is determined by equivalence across the following critical parameters:

• Zener Voltage: 24 V nominal
• Power Dissipation: 500 mW maximum
• Impedance: 35 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
• Automotive Grade: AEC-Q101 qualification
• Regulatory Compliance: ROHS3 and REACH requirements

Substitute parts must satisfy all electrical parameters within the specified tolerances and maintain surface mount compatibility. Package variants within the SOD-80 family (QuadroMELF and MiniMELF) are considered equivalent when all electrical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

The TLZ24-GS08 is a direct electrical equivalent to the VLZ24-GS08 with identical electrical specifications across all critical parameters. Both components are manufactured by Vishay General Semiconductor - Diodes Division and maintain AEC-Q101 automotive qualification and ROHS3 compliance.

The primary distinction between these components is product status and package variant. The VLZ24-GS08 is classified as obsolete, while the TLZ24-GS08 is active and currently in production. The TLZ24-GS08 utilizes SOD-80 MiniMELF packaging compared to the QuadroMELF variant of the main part; both are SOD-80 family configurations with identical electrical performance.

For applications requiring the VLZ24-GS08, the TLZ24-GS08 provides full electrical and functional compatibility with the advantage of active product status and ongoing availability.

Frequently Asked Questions (FAQ)

Q: Are the VLZ24-GS08 and TLZ24-GS08 electrically identical?

A: Yes. Both components share identical electrical specifications: 24 V nominal zener voltage, 500 mW maximum power dissipation, 35 Ohms maximum impedance, and 1.5 V maximum forward voltage at 200 mA. Operating temperature range, automotive grade, and AEC-Q101 qualification are equivalent.

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

A: Both QuadroMELF and MiniMELF are SOD-80 package variants. The primary difference is physical size, with MiniMELF representing a more compact form factor. Electrical performance and pin configuration remain identical.

Q: Can the TLZ24-GS08 be used as a direct replacement for the VLZ24-GS08 in existing designs?

A: The TLZ24-GS08 is electrically compatible with the VLZ24-GS08. PCB layout compatibility depends on the specific footprint used for the original QuadroMELF package. Verification of physical dimensions and pad spacing is required before implementation.

Q: Why is the VLZ24-GS08 classified as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The TLZ24-GS08 represents the active equivalent in the Vishay product line.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the VLZ24-GS08 and TLZ24-GS08 are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these components?

A: Both components have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
