Engineering Selection Recommendations

The TLZ2V4-GS08 is a direct electrical equivalent to the VLZ2V4-GS08 with identical performance specifications across all critical parameters. Both components are manufactured by Vishay General Semiconductor - Diodes Division and maintain full compliance with AEC-Q101 automotive qualification and RoHS3 environmental standards.

The primary distinction between these parts is the package variant designation (QuadroMELF versus MiniMELF) within the SOD-80 form factor. Both variants are surface mount configurations with compatible footprints and electrical characteristics.

The TLZ2V4-GS08 offers the advantage of active product status with confirmed inventory availability (856 pieces in stock), whereas the VLZ2V4-GS08 is classified as obsolete. For new designs and ongoing production requirements, the TLZ2V4-GS08 is the appropriate selection to ensure long-term component supply continuity.

Frequently Asked Questions (FAQ)

Q: Are the VLZ2V4-GS08 and TLZ2V4-GS08 electrically interchangeable?

A: Yes. Both components have identical Zener voltage (2.4 V), maximum power rating (500 mW), impedance (100 Ohms maximum), forward voltage characteristics (1.5 V @ 200 mA), and operating temperature range (-65°C to 175°C). All electrical parameters are equivalent.

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

A: Both are SOD-80 surface mount package variants. The QuadroMELF (VLZ2V4-GS08) and MiniMELF (TLZ2V4-GS08) designations refer to different physical configurations within the SOD-80 standard. The MiniMELF variant is the current active production format.

Q: Can I use TLZ2V4-GS08 as a direct replacement in existing designs?

A: The TLZ2V4-GS08 is electrically and mechanically compatible with the VLZ2V4-GS08. PCB footprint compatibility depends on the specific layout design. Verification of physical dimensions and pad spacing against your current design is necessary prior to implementation.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the VLZ2V4-GS08 and TLZ2V4-GS08 are automotive-grade components qualified under AEC-Q101 and are ROHS3 compliant. Both maintain moisture sensitivity level 1 (unlimited).

Q: Why is the VLZ2V4-GS08 listed as obsolete?

A: The VLZ2V4-GS08 has been superseded by the TLZ2V4-GS08 in the manufacturer's product line. The TLZ2V4-GS08 provides identical electrical performance with active production status and improved supply availability.

Q: What is the current inventory status?

A: The VLZ2V4-GS08 has 1070 pieces available as new original stock. The TLZ2V4-GS08 has 856 pieces available as new original stock with active product status.
