Substitute Part Grouping Explanation

Substitution of the VLZ6V2-GS08 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters (Critical for Functional Equivalence):

Zener voltage nominal rating: 6.2 V
Maximum power dissipation: 500 mW
Maximum impedance: 10 Ohms
Forward voltage maximum: 1.5 V @ 200 mA
Operating temperature range: -65°C ~ 175°C

Mechanical Parameters (Critical for Physical Compatibility):

Mounting type: Surface Mount
Package family: SOD-80 (includes QuadroMELF and MiniMELF variants)

Compliance Parameters:

RoHS3 compliance
Automotive grade qualification (AEC-Q101)

The substitute part TLZ6V2-GS08 meets all critical electrical specifications and operates within the same temperature range. Both parts are manufactured by the same supplier, carry identical zener voltage and power ratings, and maintain AEC-Q101 automotive qualification. The primary distinction is packaging variant (QuadroMELF versus MiniMELF) and product status (obsolete versus active).

Engineering Selection Recommendations

The TLZ6V2-GS08 is a direct functional equivalent to the VLZ6V2-GS08 based on electrical parameter equivalence and compliance certifications. Both components are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical zener voltage, power rating, impedance, and forward voltage specifications across the full operating temperature range.

The TLZ6V2-GS08 carries active product status, whereas the VLZ6V2-GS08 is obsolete. This distinction is significant for supply chain planning and long-term availability assurance. Both parts are AEC-Q101 qualified and ROHS3 compliant, meeting automotive-grade requirements.

The packaging variant difference (QuadroMELF versus MiniMELF) represents a physical form factor distinction within the SOD-80 family. Both variants are surface mount configurations with compatible footprint characteristics for SOD-80 applications. PCB layout and thermal management considerations should account for the specific package geometry of the selected substitute.

Frequently Asked Questions (FAQ)

Q: Can TLZ6V2-GS08 directly replace VLZ6V2-GS08 in existing designs?

A: Yes. The TLZ6V2-GS08 meets all electrical specifications of the VLZ6V2-GS08, including zener voltage (6.2 V), power rating (500 mW), impedance (10 Ohms maximum), and forward voltage characteristics. Both are AEC-Q101 qualified and ROHS3 compliant. Substitution is electrically valid.

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

A: Both are SOD-80 surface mount packages. QuadroMELF and MiniMELF represent different physical form factors within the SOD-80 family. The primary difference is package size and thermal characteristics. Verify PCB footprint compatibility with your specific design before substitution.

Q: Why is the VLZ6V2-GS08 listed as obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued active production and support for this part number. The TLZ6V2-GS08 represents the active equivalent, ensuring continued availability and supply chain support.

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

A: No. Both the VLZ6V2-GS08 and TLZ6V2-GS08 carry identical compliance certifications: AEC-Q101 automotive qualification and ROHS3 compliance. Substitution does not introduce compliance risk.

Q: What parameters must remain constant for substitution validity?

A: Zener voltage (6.2 V), maximum power dissipation (500 mW), maximum impedance (10 Ohms), forward voltage (1.5 V @ 200 mA), and operating temperature range (-65°C ~ 175°C) must remain unchanged. Surface mount mounting type and SOD-80 package family must be maintained.
