VLZ6V2-GS18 Equivalent & Substitute Parts

Part Overview

The VLZ6V2-GS18 is a Zener diode rated at 6.2 V nominal voltage with 500 mW maximum power dissipation, manufactured by Vishay General Semiconductor - Diodes Division. This component is designed for surface mount applications in the SOD-80 QuadroMELF package format and operates across the temperature range of -65°C to 175°C. The part carries automotive-grade qualification under AEC-Q101 and is ROHS3 compliant.

The VLZ6V2-GS18 is classified as obsolete. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design flexibility is required for procurement optimization. Substitute parts must maintain electrical equivalence across all critical parameters including zener voltage, power rating, forward voltage characteristics, and thermal operating range.

Substitute Part Grouping Explanation

Substitution of the VLZ6V2-GS18 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Zener voltage: 6.2 V nominal
• Maximum power dissipation: 500 mW
• Maximum impedance: 10 Ohms
• Forward voltage: 1.5 V maximum at 200 mA
• Operating temperature range: -65°C to 175°C minimum

Mechanical and Compliance Requirements:

• Package format: SOD-80 surface mount
• Automotive grade qualification: AEC-Q101
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The TLZ6V2-GS18 qualifies as a direct substitute because it maintains all electrical parameters within the specified limits and meets all compliance and qualification standards. The primary distinction between the main part and the substitute is the package variant designation (QuadroMELF versus MiniMELF) and product status (obsolete versus active), with both variants conforming to the SOD-80 physical specification.

Parameter Comparison

Engineering Selection Recommendations

The TLZ6V2-GS18 is a qualified substitute for the VLZ6V2-GS18 based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters are identical between the main part and substitute, including zener voltage, power rating, impedance, and forward voltage characteristics. The operating temperature range is equivalent across both components.

Compliance and Certification: Both components carry automotive-grade qualification under AEC-Q101 and are ROHS3 compliant. Moisture sensitivity level is identical at MSL 1 (Unlimited). REACH status is unaffected for both parts.

Product Status Advantage: The TLZ6V2-GS18 maintains active product status with Vishay General Semiconductor - Diodes Division, whereas the VLZ6V2-GS18 is classified as obsolete. Selection of the active substitute ensures continued availability and supply chain stability.

Package Consideration: Both components conform to the SOD-80 physical specification. The distinction between QuadroMELF and MiniMELF variants represents different internal lead frame configurations within the same external package envelope, maintaining mechanical and electrical compatibility for PCB assembly and circuit operation.

Frequently Asked Questions (FAQ)

Q: Can the TLZ6V2-GS18 be used as a direct replacement for the VLZ6V2-GS18 in existing designs?

A: Yes. The TLZ6V2-GS18 is electrically and mechanically equivalent to the VLZ6V2-GS18. All critical parameters including zener voltage, power dissipation, impedance, forward voltage, and operating temperature range are identical. Both components are qualified to AEC-Q101 automotive standards and are ROHS3 compliant.

Q: What is the difference between the QuadroMELF and MiniMELF package variants?

A: Both variants conform to the SOD-80 physical specification and are compatible with the same PCB footprint. The internal difference relates to lead frame configuration, but this does not affect electrical performance or circuit operation. Both variants are suitable for surface mount assembly.

Q: Why is the VLZ6V2-GS18 classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on production lifecycle decisions. The TLZ6V2-GS18 is the active equivalent offering from Vishay General Semiconductor - Diodes Division and provides continued access to the same electrical and functional specifications.

Q: Are there any thermal or reliability differences between these two parts?

A: No. Both components operate across the identical temperature range of -65°C to 175°C and carry the same automotive-grade qualification. Moisture sensitivity level is equivalent at MSL 1 (Unlimited).

Q: What packaging format is the TLZ6V2-GS18 supplied in?

A: The TLZ6V2-GS18 is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount production. The VLZ6V2-GS18 packaging format was not specified in the available data.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the VLZ6V2-GS18 and TLZ6V2-GS18 carry automotive-grade classification and AEC-Q101 qualification, making them suitable for automotive circuit applications requiring zener diode functionality.
